Sampling the satellite image into pixels on the Gray scale

Good day, I am taking a satellite image (already black and white as shown in the picture) and I want to sample it into picture elements (pixels) such as the brightness of each pixel is represented by a numeric value described on the gray level scale (8 bits) so that I could get and access the data data in the form of a histogram. Since my know about image processing in matlab is quite poor can you please specify how to get the image in matlab and perform the required computations. Thank you

The imhist function may be what you’re looking for.
