i am trying to import the matlab codes for the image to be converted to rgb,binary,hsl and grey..bt when ever i innput an image the output is a pure blak image.kindly help me out.i am posting ma vi too.

Could be a problem in passing the datatypes and how this "other software" is handling that.

Don't you have the NI Vision Development System to do this?

In the VI you attached, the array is not wired from the script node to the "IMAQ ArrayToColorImage" VI.  What happens when the 'H' array is wired?

I can't help you do this in a text based language but we do have vision software that can do what you need.  We also have the Machine Vision forum.

Text based programming isn't a strength of mine, sorry.
