I'm developing a code to detect objects in an image through the algorithm of Viola and Jones, but it did not work out perfectly because the image has many details. So I decided to start by first detecting the color and then defining the objects through recognition. How can I detect green colors in an image? Since I'm grateful!

在 MATLAB Online 中打开

See color detection is very vast topic, any color generation based on three components R, G,B.

Green color also varies from lower to maximum.

Are you looking for those pixels which having R=0,G=Maximum Level, and B=0? In 8 bit image it would be (0,255,0)

green_component=imageRGB(:,:,2)

I can detect it with your code KALYAN ACHARJYA . However the lighting of the image influences a lot. Is there any function or code that leaves the illumination in the uniform image?
