First you have to identify the object to be isolated. Then draw a border around that object such that the difference of pixels values along that border crosses a certain threshold.
You can also use a high pass filter on the image and then comparing the output from HPF with the original (by matlab script) find out the border. In this case the d

nice. from there you can start counting the red pixels based on the RGB function, image(x,y,1:3)... where x and y is their coordinates while 1:3 will tell the RED, GREEN and BLUE values.
since you want the RED pixels, then you can select your RED threshold values and count those pixels.
count = 0;
