My question about images in Matlab: Why is the color value of pixels sometimes represented by integer numbers such as:
Pixel information(X,Y) [R G B]= (10,20) [139, 104, 172]
and other times by fractional values such as:
Pixel information(X,Y) [R G B]= (10,20) [0.5373, 0.529, 0.5059] , ??
you can select color picker from mathworks web site to add your color in your matlab code its helpful
Why ?? Because they are normalized , it is generally done for object recognition and also to resemble the color (according to McAdam's ellipse )
To understand in better way, I would like to refer you the article:
https://www.mdpi.com/2079-9292/8/3/315/htm
You can see Figure 10, how the pixel values are normalized from 0-255 to 0-1. Moreover, it was useful to extract the desired information.
you can also search in mathworks.com and find matlabcentral its totally researcher group and they can share their all about project there you can find out easily.
