In image processing, we often need to convert real-color images into black and white images. Strictly speaking, it should be a grayscale image, because the real black and white images are only pure black and pure white. Before getting started, let's briefly add the image representation principles in the computer. Images in computers can be roughly divided into bitmap and Metafile ). Bitmap can be regarded a

){Delete [] data;Delete [] pdataconv;Return 0;}Pai_stdio_dest ( JCs, F ); 3. Set the compression parameters. The main parameters include the image width, height, and number of color channels (1: index image, 3: others). The color space (jcs_grayscale indicates the grayscale image, jcs_rgb indicates color image), compression quality, etc., as follows: JCs. image_width = nwidth; // the width and height of the graph, in pixels.JCs. image_height = nheight

CMYK to multiple channels Multi-channel patterns are usually present as intermediate transition modes for channel splitting and merging. In the opening section of this chapter, the reader has rehearsed the different effects of the channels under different combinations of rules (RGB, Lab, or CMYK). A much larger use of multichannel mode is in printing. If you convert a CMYK-mode image to multichannel mode, CMYK cyan, magenta, yellow, and black channe

, in the printing should be more pure black.The electronic files used for printing must be four-color files (C, M, Y, k). Files in RGB color mode cannot be used for printing and output. Remember !!4. What is color separation? Is color separation so important? How to separate colors in Photoshop?A: color separation is a term used for printing. It refers to the four primary colors of the original article, namely, yellow, magenta, blue, and black; in computer printing design or graphic design image

I want to change the csdn account's profile picture to my real profile picture, but I don't want to change it so directly. I just want to convert the profile picture into a two-value diagram, because the original image cannot be pushed out from the binary image. This process requires two functions of opencv. The first function is to convert a color image to a grayscale
