Here is the calculation from wiki - Indexed Color: "Indexed color saves a lot of memory, storage space, and transmission time: using truecolor, each pixel needs 24 bits, or 3 bytes. When I import my image using the imread function, I get a map with only zeros (map = []). I want the RGB components of the image, but cannot get them since this requires the picture's colormap (which is … In OpenCV, you can apply different color maps to an image using the method applyColorMap() of the class Imgproc.Following is the syntax of this method − applyColorMap(Mat src, Mat dst, int colormap) OpenCV now comes with various colormaps to enhance the visualization in your computer vision application. #java.

The following are 30 code examples for showing how to use cv2.applyColorMap().These examples are extracted from open source projects. img_COLORMAP_HSV = cv2.applyColorMap(gray_img, cv2.COLORMAP_HSV) Finally, we are going to apply all the color maps to the same grayscale image and plot them in the same figure. In this tutorial we will first show a simple way to pseudocolor / false color a grayscale image using OpenCV’s predefined colormaps. We will also show a way to define a custom colormap if you would rather use your own. This rgb2ind() converts RGB image to indexed image. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. opencv.
