A long time ago, when there is no DW, we will have a grayscale connection. [Ctrl + A full selection Note: If you need to introduce external JS need to refresh to execute] 

For a 256 image with 8 pixels, some correspond to different RGB color palette, which is a pseudo-color 256 image. If the r of the corresponding RGB color palette is = G = B, this is a 256 grayscale image. For gray-scale and pseudo-color images of 256, their colors are fixed; otherwise, they will become messy. We can also see the importance of the color table, because the values in the image only provide the corresponding positions in the color table.

processing image, which can eliminate the influence of the ambient light from the image and obtain the original scene image. Algorithm execution steps:(1) There are generally two ways to determine:Either take a fixed value (such as half of the brightest grayscale value, eight-bit display is 128);Either by calculating the three-channel average value of the image, take;(2) Calculate the gain coefficient of three channels:;; ；(3) According to von Kries

Tutorials are a practical and quick way to handle grayscale photos. Train of thought: First use the color level, curve and other enhancement picture brightness and contrast, in use to the character, background and other complementary color, finally appropriate sharpening the effect came out, very natural! Original Final effect 1, open the picture, click on the red circle to create a color adjustment layer. 2, re

This article describes a method based on DirectX MMX to implement image grayscale processing, to compile this program need DirectX SDK5.0, code required ddutil.h and ddutil.cpp files, please download the project. Compiled in a WINDOWNT4.0+SP3 environment, the code has been collated and contains comments. as follows: #include Interested friends can debug run the example of this article, I believe that you will be in C + + project development

The transformation function of color graph to gray scale I always remember, and the common header file is always easy to remember confusion, OpenCV write too little. And on the Internet to find related things, many are based on opencv2.0, and the

Convert color images to gray images, directly using the. NET interface to traverse each pixel point conversion is very inefficient, 800K picture 650,000 pixels My computer takes 5 minutes, and with unsafe, the speed increases thousands of times

First, the basic concept of copying objectsCopy an object as a copy and open up a new piece of memory to store the replica object.Second, if an object wants to have the function of copying, must implement Agreement and AgreementNSObject's Common

When the exercise is done, the effect is not good. The CPU does not provide a command such as pmulluw. The processing effect is obviously different from that of Matlab, especially the background. I can't find the problem, but it is most likely on

In opencl programming, especially GPU-based opencl programming, the most important way to improve program performance is to improve memory utilization. One is to improve the overall memory read/write efficiency, the other is to reduce the bank
