You mean like subsampling the image with points on a grid
stepX = 2; % Every other column pixel.
stepY = 3; % Every third row pixel.
subsampledImage = grayImage(1:stepY:end, 1:stepX:end);
??? Otherwise specify what you do mean.

I don't know what that is. You'd best follow the instructions in the paper. I do have some color segmentation demos in my File Exchange if you want to try standard thresholding approaches. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
