Is there a way to compute the percentage of pixels in this image of a certain colour, whilst ignoring the (dark blue) background in the calculation?

Hi,
I'm trying to get the percentages of different coloured pixels in this image, but haven't found a way to either ignore the background or to ignore it in the percentage calculations. Any help would be appreciated!

If I is your image.....And your pixel value is n. Use:
idx = I==n ;
YOur idx will be a matrix with 1's and 0's...
