• Check the development of an Image with Standard of LABVIEW functions

  Hello

  I want to determine the best quality of the development of a series of color images using features standard LABVIEW, an example my images would be KING of coins in copper or similar sample 2 mm x 1 mm. I do not have the Toolbox IMAQ vision, so this will not be an option. Could someone give me an example of this or point me in the direction I must go. Is it better to check the quality of the focus on the image of color or black and white image or perhaps a representation of the intensity of the image? I heard that the gap checking type of a line of pixels in the image would give a good indication of the quality of the development by seeking the higher SD all images?

  Any help is greatly appreciated!

  Convert the image into an array to IMAQ ImageToArray.

  Extract a single line or row of the table by using the table to Index.  Assuming that your image be U8, these will be U8 values.

  Digital conversion to Double can convert the array of double values.

  Use Rotate 1-d array with an offset of 1 to turn the table.

  Subtract the table of rotation of the rotation matrix.

  Deletion of the table to delete the first element of the array.  It's the difference between the first and last items, which is not desired.

  Absolute value to convert the table of all positive values.

  Use the mean or the standard deviation to measure the development.  I usually have better results with the standard deviation, but sometimes means gives good results also.

• 500 Dignostics Performance event. could not measure the performance of video playback

  Hello

  Could someone help me with the problem of (the windows experience index) when I run the assessment I get the message (could not measure the performance of video playback).

  Hello

  ·         You have made no changes to the computer until the problem occurred?

  ·         What is the full error message or code that you get?

  Event ID 500 is mainly caused by the excessive use of graphical subsystem, which is controlled by the process dwm.exe. DWM.exe is a Desktop Window Manager and is responsible for the graphics effects in Windows operating system such as 3-d effects, previews of windows and transparencies to windows live.

  I suggest to disable all of the features of "Aero", such as the use of classic Windows rather than the Windows Aero feature, stopping using 3D desktop and so on, in order to reduce excessive system resource occupancy rates. If possible, you could develop RAM to increase performance of the system to check if the event has not changed.

  You can also try to update the graphics driver and check if it helps. To do so follow the link below:

• Windows Experience Index problem: could not measure the performance of video playback

  My pc is not yet rated. When I click on rate appears on this computer, a msg error saying that Windows Experience Index for your system could not be calculated, could not measure the PERFORMANCE of VIDEO PLAYBACK. What should I do. Help, please

  Hello

  Here are a few things to check before launching performance index Windows (WEI).

  • Quit all running programs, and restart the computer before running the assessment (WEI).
  • Check with the manufacturer of the computer or the motherboard manufacturer for BIOS updates.
  • Make sure you have the latest Windows 7 compatible drivers for the graphics device installed (video card).
  • If you have any third-party media players installed, uninstall them until the end of the evaluation of the WEI.
  • If you have installed any third-party Media Codecs, try to uninstall them until the end of the evaluation of the WEI.

  Open Windows Explorer and navigate to the folder C:\WINDOWS\Performance\WinSAT .

  You should see the following 8 videos.

  2 files with .mp4 extension.

  3 files with the .mpg file extension.

  3 files with .wmv file extension.

  Double-click each of these files. They should open and play in Windows Media Player. These are the files that WEI runs video performance.

  One thing to remember is that the WEI score is only an indicator of the ability of the main components of hardware on the computer. It has no effect on the performance of the system.

  Tell us what you find.

• Problem with WEI: could not measure the performance of video playback.

  Hello, Microsoft

  First of all I'm new to the forum, Please warn me if I posted in the wrong section, or did something wrong.

  I have a laptop, (x 86) Win7 Home Premium. Before posting, I tried everything Microsoft sugguests and nothing will do, as the update of the graphics card, etc. WEI did not work as usual today, I got the problem said: could not measure the performance of video playback.

  Hello Derek,.

  Please keep us updated on the status of the issue.

  I'm sorry for the late reply.

  The IFE can be used to show what part of the system should provide the largest increase in performance when it is upgraded. For example, a computer with the lower under-score in his memory, would benefit more than an upgrade of RAM to add a faster hard drive (or any other component).

• How to measure the performance of the disks in vcenter

  Hey guys,.

  What is the best way for me to measure the performance of the disks in vcenter? I use the iscsi SAN storage for my environment vsphere and wants to make sure that things are defeated.

  Y at - it a good way for me to measure this inside of vcenter, if what should I pay attention to the?

  Thank you

  Kevin

  Performance, Advanced tab, storage card, chart options.

  Here you can select your storage cards and view certain measures. To also have historical data (and not only in real time), you will need to change the settings of his stats in vCenter server.

  Or select a disc, and here you can see, for example the latency time.

  How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  I have a virtual network adapter that is created with Broadcom.

  This virtual interface named "BASP eCard" visible on the performance monitor in the category 'Rhythm Pipe' but not in the category "Network Interface".

  This is problematic because the Tx and Rx (bytes received/send in second) is available in "Network Interface" that show physical network cards only.

  Someone has an idea?

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)
