I am performing Plant disease I want to identify the mostly green colored pixels. After that, based on specified threshold value that is computed for these pixels, the mostly green pixels i want to masked as follows: if the green component of the pixel intensity is less than the pre-computed threshold value, the red, green and blue components of the this pixel is assigned to a value of zero. pleae give me solution for Masking the green pixels

See my "color detection by hue" tutorial in my File Exchange It can do this. Simply adapt the thresholds, by looking at the histograms, to select green instead of yellow.

At the risk of being accused of shameless self-promotion... I blogged about a similar problem on Steve Eddins's Image Processing blog. Perhaps some of my experiences might be of use?
