Hi Saad,

I understand that you want to perform image processing to analyze an oil saturation map. You can use various functions from “Image Processing Toolbox” to perform any type of image related analysis.

To obtain the intensity of each pixels, you can apply the “rgb2gray” function on the image. You can also find the saturation of each pixel by converting the image into the “hsv” format. Following is a sample code to obtain the saturation of each pixel:

hsvImage = rgb2hsv(image);
saturation = hsvImage(:,:,2);

Using these variables, you can directly create masks, filters, histograms, etc. and use the values for further analysis.

You can refer the following link to get started with image processing in MATLAB:

Hope this helps!
