When you classify it based on image segmentation (Apply various variable thresholding techniques) and count the number of objects within an image.
[label_Image, numberofObject]=bwlabel(segmented_binaryImage);

this is a sample image it's not exactly what i'm going to do cause the exact number of beans for some types is uncountable in this image, the image i'm going to work with will have less beans

Create a feature vector for each pixel that includes the mean hue, saturation, and value in a window around the pixel plus the standard deviation of the values in the window. Use rgb2hsv() and conv2() and stdfilt().
hsvImage = rgb2hsv(rgbImage);
hImage = hsvImage(:, :, 1);
sImage = hsvImage(:, :, 2);
vImage = hsvImage(:, :, 3);
windowsSize = 21; % Some odd number.
kernel = ones(windowSize, windowSize)/windowSize^2;
localMeanH = conv2(hImage, kernel, 'same');
localMeanS = conv2(sImage, kernel, 'same');
localMeanV = conv2(vImage, kernel, 'same');
% Now use stdfilt
localSDH = stdfilt(hImage, ..... etc.
I'm sure you can figure out what to do next.
