• application 2D median filter for images

  I want to use the function of median filter 1 d LabVIEW for application table 2d (image).  Vision doesn't have this feature (or I can't find not [using Vision 8.5]).  I guess I can apply the median filter 1 d through the lines, then transpose the table and apply again to the lines (really columns but now the lines because of the conversion).   Just like the use of the 1-d FFT for 2d FFT.  Is this strategy the correct?

  Thank you

  That's where - IMAQ NthOrder under treatment: Image filters.

  

  By default, it takes the middle number of a 3 x 3 around each pixel region, but can be set to be the biggest, smallest, or any place in between.  Also the ability to set the size of the filter, although it is a non-linear filter (so why it is not separable as you suggest) the time increases significantly.

• How to use the median filter?

  I need a median filter that ignores the pixels with color difference above a certain threshold. So, if the pixels are relatively narrow in the value of the color, apply median as usual. If not, ignore.

• Median filter isn't removing the spikes at the bottom

  Hi all

  I use a median filter to spikes of deletes for the acquisition of data in real time of thickness of an ultrasonic sensor. This filter works great to remove the upper tips, unfortunately the bottom spikes remains unchanged. I tried changing different grade in the median filter with no improvement.

  Attached images are code LabView and graphs showing data before and after filtering. How can I remove these spikes at bottom also?

  Thanks in advance

  I think that your problem is your acquisition code, not the filter. The data set, you have posted has 969 items with values of 2.681 or 2.68. The other 54 elements have values as 2.6, 681, 1, 2, 8 and 68. An element has the value 5, and there the value 9.

  What this suggests to me, it's that your VISA reading is not correctly synchronized with the data transmission device. Either you get partial messages or an occasional character that does not match your regular expression.  Look at the default value stored in the reading string in your VI. Unplug the display of ' \' character mode. It contains '\D5U=\F32.681\r\n2.681\r\n2.681\r\n' it looks like there two characters special \D5 and \F3 and then three values separated by carriage return, line feed. With this kind of protocol you should probably use the jump as a default line end character. Then search for the string \D2...\F2 which can be a header or channel ID. The rest is digital data.

  Check with the creator of the device that sends data to determine the complete communication protocol.

• median filter

  Hi, I am a student on filtering

  My basic test comes from the txt file with table 1 d, with the help of tool median filter, where the signal is filtered median

  But it does not work which means it does not indicate the field. I don't know why even there no error that occurred.

  Please let me know the reason.

  

  Try something like that. Filter seems to work pretty well:

  

  (Note that read the spreadsheet file has changed in LabVIEW 2015, so the red X on the icon. Just ignore that. Be sure to select "convert" so that you get the first column instead of the first row)

• Cannot use median filter inside the While loop

  Hello

  I try to use the filter median insade loop some time. This seems to be a problem. I have attached the VI. Help, please.

  This entry is a number of sample as 1,1.1,1.05. This output is zero.

  Thank you

  Since you get only one value per iteration, you can use the point-by-point version of the median filter.

• Apply a smart filter layer mask information destroyed?

  IV has applied a dynamic filter on a layer that I did a lot of work of masking on. By applying this smart filter that I lose all my information masking? Is it possible to apply the two effects on the same layer?

  Thanks for any help

  If you have converted the layer with the layer mask to a CG so the filter will be applied on this as a whole, but the layer mask will still be in the SO.

  If you want to keep the mask as a channel in the container document, for example, you can combine the layer, move the layer mask to the Group and convert the layer to a SO.

• Files of Type filter: no video filetypes?

  I upgraded from LR2 for LR3 as soon as they sent to beta testers telling us that he was available.

  When in beta, I've never really played with the video feature - I wish I did I could give your comments earlier - I'm pretty disappointed in video support.

  None of my videos will play in lightroom itself (as their demo videos show)-it always opens them to QuickTime. Video files are a 5 d MKII and I am on a Mac under 10.6.

  I could live with that - but honestly the file type filter does not display the types of video files? This means that I can not create a smart collection based on the type of file to see all my videos. What gives? I thought he would do at least that.

  I've resorted to add a keyword 'video' to all of my video files - but everyone has noticed this omission?

  The videos have never played in LR, only in the video player to use for this file type.

  You will find a video selection in the file type filter.  Don't know why you have not seen.

• Apply Color LUT Speedgrade eye video causes disappear

  I am attempting to apply a LUT created in Speedgrade to sequences within After Effects. When I use "Apply color LUT" layer is no longer visible and RAM Preview stops working (head game is not progress).

  
  

  After Effects and Speedgrade are updated the most recent versions. Does anyone have any ideas of what could be done to solve this problem? Thanks in advance!

  An update on this bug:

  One of our developers has spent some time watching this recently. He traced the problematic code and requested a fix. (The problem is a component of Adobe for the color that is shared among several applications, ACE Management).

  Until a fix is provided, you can work around the problem by using the Lumetri color effect in after effects CC 2015 (13.6), instead of applying the color LUT. Effects > utility > Lumetri color. In the effect of color Lumetri, open creative settings and changing of Look ahead, then choose the file. Take a look at.

• File Photoshop 15 can I apply paint oil filter old version

  I created a file in Photoshop 15 only to find out that there is no filter of oil painting. I saved the file and it has more than one computer with an older version, but it blocks the program when I try to run it. Can I save the file in an older version? Is there something I can do?

  It's a big complicated file and I had sold the customer on the filter of painting in oil. Help please

  The file may be too complicated for the old program. I think that your best best to make a copy of the file with just the layers you need to merge to use with the filter of the oil paint. Then you can bring the image back to your master as a layer or placed file.

• How to apply the new ratio of video (resolution, 1500 x 844) without having the black screen on the top/bottom of the video?

  Same as if I created the project for the resolution of desires, when I export the video, it has black areas, probably because is not as high that should be as a ratio FHD. If I try to pull back the file exported to the Prime Minister, it came with these black lines... No idea how to get rid of them? / I use first Cs5.

  

  Thank you very much.

  Problem solved, had to use the crop on the Panel of the export tool, to get rid of the black bars. In the upper left corner, switch to the output panel, and you will see the result.

  

• Is it possible to apply a blur filter box?

  It seems to be methods to perform almost all the filters, such as applyGaussianBlur, applyTwirl.

  But he does not have one for fuzzy box. Is there another way to achieve this filter?

  applyReduceNoise() would be nice too. All the pixelation filters are missing as well.

  Use ScriptListener to capture the area of blur.

  var idboxblur = stringIDToTypeID( "boxblur" );
      var desc2 = new ActionDescriptor();
      var idRds = charIDToTypeID( "Rds " );
      var idPxl = charIDToTypeID( "#Pxl" );
      desc2.putUnitDouble( idRds, idPxl, 10.000000 );
  executeAction( idboxblur, desc2, DialogModes.NO );
