![]() In contrast, if we use only 2 (equally spaced) bins, then we are counting the number of times a pixel is in the range. If we construct a histogram with 256 bins, then we are effectively counting the number of times each pixel value occurs. When plotting the histogram, the X-axis serves as our “bins”. ![]() If you are working in a different color space, the pixel range may be different. We are going to assume a RGB color space in this example, so these pixel values will be in the range of 0 to 255. It can be visualized as a graph (or plot) that gives a high-level intuition of the intensity (pixel value) distribution. So, what exactly is a histogram? A histogram represents the distribution of colors in an image. Grant would have been equally thrilled had he known the power of color histograms.Īnd more importantly, when the power goes out, the histograms don’t eat the tourists. ![]() Click here to download the source code to this post
