1. Several image file formats supported by MATLAB:⑴jpeg (Joint photogyaphic Expeyts Group): An image compression format called the joint Image Expert group.⑵bmp (Windows Bitmap): There are 1-bit, 4-bit, 8-bit, 24-bit uncompressed images, and 8-bit RLE (RUN length encoded) images. The contents of the file include the header (a bitmap fileheader data structure), the bitmap information block (bitmap information header bitmap Infoheader and a color table), and the image data.⑶PCX (Windows Paintbrush

Histogram is an important basic tool in digital image processing, before we discuss various spatial image processing, we must first understand the concept of histogram and its meaning. The histogram provides the statistical information of the image and provides a foreshadowing for understanding the connotation of various spatial enhancement techniques. In addition, histogram manipulation can also be used directly for image enhancement. At present, most digital cameras have the functio

. 2, grayscale belongs to the RGB color gamut (color gamut refers to the color range). Because the grayscale is formed, the RGB values are equal. The number of RGB values is equal to 256, then the amount of grayscale is level 256. In addition to pure white and pure black, there are 254 kinds of intermediate transition colors. Pure black and

. The ideal font has a smooth edge transition, and when displayed on the screen, the font grid (rasterization) needs to be a pixel. Using Black-and-White rendering does not reflect the details of the font, causing the edge to appear jagged (jagged) is not smooth. To address this problem, the font rendering engine uses the following methods for smoothing (antialiasing): Grayscale (grayscale) rendering, Subp

Two phenomena clearly indicate that perceived brightness is not a simple function of intensity. The first phenomenon is based on the fact that visual systems tend to have "undershoot" and "overshoot" phenomena at the boundary of different intensity regions. The second phenomenon, called simultaneous contrast, relates to the fact that the brightness of the sensing area is not simply determined by its intensity. The color of a person's perceived object is determined by the nature of the light refl

This work can be achieved through digital cameras,DV machines, industrial cameras, computer digital cameras, mobile phone cameras and other equipment to collect, and to obtain the image information we want to analyze. (b) layout Analysisafter obtaining the image information, the whole layout of the image should be analyzed. This step is inefficient if you use a generic algorithm for analysis. In general, it is necessary to m

　　Before you learn the contents of this chapter, be sure to hold the color basics of the lesson in front of you. 　　by learning the basics of color, we know that each pixel has a corresponding brightness, this brightness and hue is not related, the same brightness can be either red or green, as in black and white (grayscale) television, like the image of a single gray can not determine whether it is red or green. therefore, the brightness and hue of t
