in labview how can vision 2013 I extract image from plane red color color image in fromRGB?

...

Okay, now I have what I consider to be an "acceptable" solution showing the R, G and B had an Image color.  He doesn't require a "pixel-by-pixel" approach that I posted yesterday, but works directly with color plans you get the RGB image splitting in his 3 grey U8 images.

I enclose a demo project that I saved in LabVIEW 2012.  It is quite rudimentary - you provide a picture (I used the Microsoft sample pictures folder Desert.jpg) and it shows you the Image and the red, green and blue color had.  A switch allows you to view the plans of color and the scales of gray U8 (very easy), but also allows you to consider the R, G and B channels of color (a little harder to do).  In the latter case, the Image is, indeed, not the original Image, but the Image resulting from recombination R + G + B.

For this image to 1024 x 768 pixels, decomposition and display three color plans updated to (I estimate here) 100 times per second.  When using the gray scales, it was about 20 times faster (note that color requires make first of all the gray scale, as well as each resulting image R, G and B requires 4 bytes instead of 1 byte per pixel).

Here is the front - note that the blue channel has almost nothing except 'sky', while the reddish rocks are particularly acute in the red channel.

    Problem: The program "HP updates Agent" run frequently and on no particular schedule, certainly not the one I chose.  He takes over my computer for hours and using most of the CPU, fluctuating between 13% and 87% to 1 etc.3% at 6%, etc.. The computer crashes and I can not use it for something else. On the HP updates screen, I put updates on 'NEVER', but that did not work.  The programs always run. In the Windows Task Manager window, the program is called "Agent updates from HP".

    I find nothing on this problem in the base of support.

    How can I disable the Agent updates from HP running?

    Select your Start button, in the search box type 'msconfig' then msconfig.exe under programs.
