WebGray color is actually the mid point of black and white. That said, In case of 8bpp, the pixel value that denotes gray color is 127 or 128bpp (if you count from 1, not from 0). Image storage requirements After the discussion of bits per pixel, now we have every thing that we need to calculate a size of an image. Image size WebOct 16, 2024 · In the first step, we calculate both histogram and the equalized histogram of both A, and B. Then we need to map each pixel of A, based on the value of its equalized histogram to the value of B. So, for example for pixels with the intensity level of 0 in A, the corresponding value of A equalized histogram is 4.
