Designed Program for Color Image Processing Based on Pseudo-color Space
Abstract: Pseudo-color processing is a kind of method which turns different kinds of gray level of black-and-white image into pseudo-color image with different color according to the linear or nonlinear mapping function. It makes the original images more easier to identify, and more easier to highlight the target. What’s more, the thesis also discusses the theory of color processing and the gray processing. In the design, by using “weighted average method” and “averaging method” and “maximum method”, it realizes that the color image changes into the gray image. Besides the thesis also analyzes the method which turns a gray image into a pseudo-color image, that by using density slice and Grayscale-color transformation method it realizes the changing from the gray image which only has 256 levels image brightness; To design the program, it uses the C# language to finish the pseudo-color processing, and it also realizes the basic bitmap image classes, the graying and the pseudo-color changing. In order to strengthen the goal, inversing color, sharpen and soften program is added. By using the language of C# makes the program shot but encapsulates. In the experiment, the efficiency of the program is enhanced, and the image detail is displayed.
