How can we find areas of same colour in a picture

[OZI]

Hi,

we are using Vision Assistant 2012 and we want to analyse a coloured picture to find areas of same (plain) colour. That means we have a coloured picture with artworks and text and we want to find the areas which have the same colour without any text or anything else in it.

Does anyone have an idea how to do this on an easy way?

Thanks in advance

best regards

Oliver

You could use a color threshold and set the RGB ranges to encapsulate only the color ranges you want to find.  This will give you a binary image with all of the detected colors being 1 and all other pixels being 0.  You may also want to use a partical filter to get rid of any small blobs.  What do you want to do with these detected sections of color once you find them?
