MATLAB: I have an image with red,yellow and green pixels. How to find the percentage of yellow pixels

image processing

I have used red=img(:,:,1) and green=img(:,:,2) for the red and green pixels respectively.Is there any similar way to extract yellow pixels?

Best Answer

yellow = red == 255 & green == 255;

if you are using a uint8 image or replace 255 with whatever the data maximum is otherwise.

First of all, you shouldn't use highly compressed jepg images for image analysis or else you get bad artifacts like you're seeing.

The "square" is the outermost object and will have label 1. So label everything and remove it. Something like this (untested off the top of my head);

[labeledImage, numberOfRegions] = bwlabel(binaryImage);
% Binarize the labeled image to get back to a binary image again.
binaryImage = labeledImage > 1; % Keep all except region #1.

MATLAB: Increase RGB image saturation.

This is easier in HSV colorspace:

RGB = rand(100, 100, 3);
HSV = rgb2hsv(RGB);
% "20% more" saturation:
HSV(:, :, 2) = HSV(:, :, 2) * 1.2;
% or add:
% HSV(:, :, 2) = HSV(:, :, 2) + 0.2;
HSV(HSV > 1) = 1;  % Limit values
RGB = hsv2rgb(HSV);
