Hi,

You forget to enclose the "IVA GrayFilter.vi" so I removed it and when running our VI I was receiving an error that says the image is too small to perform the convolute operation, so I also removed the "convolute" and here is the result I got :



just to show you, here is a screen-shot of the code :




Hope this helps

thanks TiTou

the IVA GrayFilter.vi was generated by vision assistant,  after i removed convolute, it works ,but not stable.

i add a "IMAQ creat" vi to the extractsinglecolorplan's image Dst ,then the hole programs works fine.
