My project is want to enhance the hand vein image. The problem is I need to display some values on the vein. For example, pixel values, SNR and MSE. Below I attached the code to get the pixel values but I don't understand why the value have 3.
imshow 'hazirah.jpg';
pixel_values = impixel;

You have 3 values because it's a color image. Those are the red, green, and blue intensity values.
rgbImage = imread('hazirah.jpg');
imshow(rgbImage);
impixelinfo; % Mouse around and see values.
row = 1; % whatever you want.
collumn = 4; % whatever you want.
pixel_values = impixel(rgbImage, row, column);
