how to get pixel value of each pixel of a gray-scale or black-white image?
posted 5 years ago
can any one suggest me the method to get actual pixel value of each pixel of a gray scale image?
i used this code to get pixel. But it just gives me red value of an pixel? I don't know that black-white or Gray Scale image contains RGB pixels or not, So please tell me that, the method i used is right or wrong? And also when i plotted histogram for my image it was exactly opposite to the imajeJ histogram for same image. So i guess my method to grab pixel of Gray Scale image is somewhere wrong
So If it is wrong what is the right way to get pixel.
here is my code
