Improving the performance of the loop

• Improve the performance of processing image javaFx

  Hello

  I'm working on Image processing with javaFx. I think my code isn't effective favorite (with pictures HD, refresh is very slow). Because I am doing a 'for' on each pixel of my image every time I have to refresh it. But I don't know how else to do.

  So I need help to improve the performance of my treatment.

  This is my code:

  import javafx.application.Application;
  import jvafx.beans.InvalidationListener;
  import javafx.beans.Observable;
  import javafx.beans.property.DoubleProperty;
  import javafx.scene.Scene;
  import javafx.scene.control.ScrollPane;
  import javafx.scene.control.Slider;
  import javafx.scene.image.Image;
  import javafx.scene.image.ImageView;
  import javafx.scene.image.PixelReader;
  import javafx.scene.image.PixelWriter;
  import javafx.scene.image.WritableImage;
  import javafx.scene.layout.AnchorPane;
  import javafx.scene.paint.Color;
  import javafx.stage.Stage;
      
  public class Example extends Application {
  
      private Image src;
      private WritableImage dest;
      private int width;
      private int height;
       int value = 0;
  
      @Override
      public void start(Stage stage) {
          AnchorPane root = new AnchorPane();
          initImage(root);
          Scene scene = new Scene(root);
          stage.setTitle("Demo processing");
          stage.setResizable(false);
          stage.setScene(scene);
          stage.show();
      }
  
      private void initImage(AnchorPane root) {
          src = new Image(
                  "http://mikecann.co.uk/wp-content/uploads/2009/12/ScreenHunter_02-Dec.-10-19.41-1024x484.jpg");
          width = (int) src.getWidth();
          height = (int) src.getHeight();
          root.setPrefSize(800, 800 + 50);
          ScrollPane scrollPane = new ScrollPane();
          scrollPane.setPrefHeight(600);
          scrollPane.setPrefWidth(1000);
          dest = new WritableImage(width, height);
          ImageView destView = new ImageView(dest);
  
          scrollPane.setContent(destView);
  
          root.getChildren().add(scrollPane);
          AnchorPane.setTopAnchor(scrollPane, 0.0);
  
          Slider slider = new Slider(0, 255, 1);
          slider.setPrefSize(800, 50);
          slider.setShowTickLabels(true);
          slider.setShowTickMarks(true);
          slider.setSnapToTicks(true);
          slider.setMajorTickUnit(1.0);
          slider.setMinorTickCount(0);
          slider.setLayoutY(700);
          slider.valueProperty().addListener(new InvalidationListener() {
              @Override
              public void invalidated(Observable o) {
                  value = (int) ((DoubleProperty) o).get();
                  color();
              }
          });
          root.getChildren().add(slider);
          color();
      }
  
      private void color() {
          PixelReader reader = src.getPixelReader();
          PixelWriter writer = dest.getPixelWriter();
          for (int x = 0; x < width; x++) {
              for (int y = 0; y < height; y++) {
                  Color color = reader.getColor(x, y);
                  double red = (double) value * x * y / (width * height) / 255;
                  double green = color.getGreen();
                  double blue = (double) value * ((width * height) - x * y)
                          / (width * height) / 255;
                      writer.setColor(x, y, Color.color(red, green, blue));
                  }
              }
          }
  
          public static void main(String[] args) {
              launch(args);
          }
      }
  

  And that's with full HD picture:

              src = new Image(
                  "http://www.freedomwallpaper.com//nature-wallpaper-hd/hd_sunshine_hd.jpg");
  

  As you change each pixel independently, there really is no other way than to use a loop through the pixels. Working directly with the pixel data, rather than use setColor and getColor (...) (...) seems to give some performance enhancements. And there are some general performance enhancements, you can use (reorder the loops, calculate the value used repeatedly, etc.). The performance of this version seems acceptable on my system:

• Help improve the performance of a procedure.

  Hello everyone,
  
  First of all to introduce myself. My name is Ivan and I recently started to learn the SQL and PL/SQL. Then don't go hard on me. :)
  
  Now let's move on to the problem. What we have here is a table (a large, but we will need only a few fields) with some information about the calls. 'S called it table1. There is also another, absolutely the same structure, which is empty and we must transfer the recordings of the first.
  The calls short (less than 30 minutes) have segmentID = "C1".
  Longer calls (over 30 minutes) are saved as multiple records (1 for every 30 minutes). The first record (the first 30 minutes of the call) a segmentID = "C21". It's the first time we have only one of them for each different call. Then we have the next parts (the middle one) of the appeal, having segmentID = "C22". We have more than 1 middle part and once again the maximum minutes in every 30 minutes. Then we have the last part (new max 30 minutes) with segmentID = "C23. As with the first, we can have that last part.
  So far so good. Now we need to insert these call records in the second table. The C1 are easy - a record = one call. But those partial we must combine so that they become a single whole call. This means that we must be one of the first pieces (C21), find if there is a middle part (C22) with the same caller/called numbers and with the difference in 30 minutes time, then additional research if there is an another C22 and so on. And finally, we search for the last part of the call (C23). As part of this research we sum the length of each part, so we can have the duration of the call at the end. Then, we are ready to be inserted into the new table as a single record, just with the new duration.
  But here's the problem with my code... The table a LOT of files and this solution, despite the fact that it works (at least in tests I've done so far), it is REALLY slow.
  As I said I am new to PL/SQL and I know that this solution is really newbish, but I can't find another way to do this.
  
  So I decided to come here and ask for some advice on how to improve the performance of this.
  
  I think you're getting confused already, so I'll just put some comments in the code.
  
  I know this isn't a procedure as at present, but it will be once I have create better code. I don't think it's important for now.

      select * from table1
      where segmentID = 'C22'
      order by start_date_of_call;

  This is my first post here so I hope it's the right subforum.
  I tried to explain it as deep as possible (sorry if it's too long) and I kinda think that code got a bit hard to read with all these comments. If you want I can delete them.
  I know that I'm missing a lot of knowledge for all the help is really appreciated.
  
  I thank very you much in advance!

  Hi and welcome to the forums.

  Thanks for posting your code (and using code tags... it's a miracle of a novice!).

  What would be nice would be if you could provide some example data and expected results; as described in the FAQ: {message identifier: = 9360002}

  Your code is very likely to be slow because of the number of nested loops cursor that you use. Which is known in the trade as treatment of rank by rank (more affectionately known as slow-by-slow transformation, as he was known to be slow). It is slow because the PL engine must keep going back and forth between himself and the SQL engine and the INSERT you in a loop called SQL much time to insert data.

  Usually this kind of thing can be achieved by using something like a single INSERT... ... SELECT statement where the SELECT all the treatment that you put in the language PL, or sometimes a SQL MERGE statement if a conditional is sort of insert/update.

  If you post your data so people can get an idea of what is the logic (and have something to test with and know what results should be) then we can help.

• How to improve the performance of the Intel X 3100 on Satellite L300

  Hello everyone.

  First of all, I don't know if this is an appropriate place to post this thread here or no, but I would like to share with you the experience relating to the improvement of Intel X 3100 (GMA965).

  As we know, there is no driver is good for this chipset from Intel for the moment, especially on VIsta.
  This improvement is made by editing the registry of Intel driver.

  * Steps: *.
  * 1 * open run (Windows + R)
  * 2 * enter Regedit
  * 3 * open the subfolder: * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ *.
  * 4 * from there you'll see lots of subfolders in video, open each one until you see the folder * 0000 * with + _3DMark03.exe +.
  (For example, my is {HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ {B5990899-FBCB-45E1-B0B0 *} and reg DWord _3Dmark03.exe lies in two subfolders * 0000 * and * 0001 *})
  * 5 * in * 0000 * and * 0001 *, create two new * DWORD format: * _software.exe* and * ~ software.exe*, value = 1 (hexadecimal). Here, * software * represents the name of the program you want to accelerate as * _photoshop.exe* and * ~photoshop.exe*
  * 6 * in these files, search for * GFX_Options * and change its value to * 1 *.
  * 7 * restart your computer to activate GFX
  * 8 * repeat step 4 to add more programs you want

  Other updates for the drivers are under developed. However, this method will help you to speed up your computer performance with + heavy + graphical software required. I got double FPS on some software on my Toshiba L300 using this method such as Corel, WarcraftIII and Titan Quest (24-32 fps measurement by Fraps)

  Hope it's useful for everyone.
  Best wishes

  I own a Macbook pro mid 2012. Now I want to increase the RAM of 4 GB to 8 GB, please suggest if this update will help me to improve my performance to macbook.

  It will help in cases where the applications require more than 4 GB of RAM.  Otherwise, there will be no noticeable difference.  If you really want to increase the speed, an SSD is the best option.  They cost about 3 x's + more than a traditional HDD of same capacity...

• How to improve the performance of XControl?

  Hi all

  LabVIEW 2009 + DSC

  Following project example, there are 1 XControl and tester.vi. My goal was to display object flexible to build (1 XControl) because my user interface varies a lot depending on the current configuration of the client. The amount of these XControls are in general 100-200 pieces per display. The problem is that this structure of code generates much CPU load (even it's very simple). This can be seen easily when tester.vi is set to run. In general is it a way to improve the perfomance XControl?

  Some ways to improve performance:

  1. Never use a value property when you can use a local variable.  The difference in speed is two or three orders of magnitude.  You have several instances of this.
  2. Consider changing your data structure so that the number of the object and the position of the object are parallel arrays.  This allows to easily search item number using the primitive Research 1 table D , then check out the item appropriate to the position of the object by using the Table of Index.
  3. You should really not have anything in the XControl enabling to stop or delay the execution, because this will block your user interface thread.  Your VI popup for this.  If you need to pop up a dialog, run it with the method run a VI wait until is set to FALSE and Auto have Ref set to TRUE. To communicate the result to the XControl, drop a control hidden on the Panel before the XControl, pass a reference to this control in your dialog box, then use the value (signalling) method to contact the XControl to the dialog box.  Use a change in the value of the hidden control event to manage the receipt of data on the XControl.

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.

  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.
