Gray-level co-occurrence Matrix from an image Gray-scale symbiosis matrix of imagesGray-scale co-occurrence matrix is a matrix function of pixel distance and angle, which can reflect the comprehensive information of the image in direction, interval, amplitude and speed by calculating the correlation between the two-point gray scale of certain distance and certain direction in the image.How to use:GLCM = Graycomatrix (I)GLCMs = Graycomatrix (I,param1,val1,param2,val2,...)[Glcms,si] = Graycomatrix

With histogram assistance, four gray-scale transformations can be implemented, including linear gray-scale transformation (grayscale stretching), gray-scale logarithm transformation, gray-scale gamma transformation, and gray-scale piecewise linear transformat

Three methods to gray Web Images: Gray I always like grayscale images because I think they look more artistic. A lot of image editing, such as Photoshop, can easily turn your color image into grayscale. You may even choose to adjust the color depth and tone. Unfortunately, it is not easy to achieve this effect on the network, because there are differences in browsers. 1. CSS Filter Using the CSS Filter at

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 the pixel are irrelevant. It is wrong to say that green is brighter than red. We can do it. Using the third drawing m

first, the concept of image histogram Image histogram is a statistical table that reflects an image pixel distribution, in fact, the horizontal axis represents the type of image pixels, can be grayscale, can also be color. The ordinate represents the total number of pixels in the image for each color value or the percentage of the number of pixels. Images are made of pixels, because histograms that reflect the distribution of pixels can often be used

Image enhancement is a pixel-to-pixel operation that changes the grayscale histogram of an image in a predetermined manner. Sometimes referred to as contrast enhancement, gray-level transformations. The point operation is unlikely to change the spatial relationship within the image, and the grayscale value of the output pixel is determined by the value of the input pixel. Its role:Contrast enhancement: Expa

chart with full color in RGB mode. Saturation: indicates the purity of the color. if it is 0, the color is used. White, black, and other gray colors have no saturation. At the maximum saturation, each color has the most pure color. Brightness: bright reading of colors. If it is 0, it is black. The maximum brightness is the most colorful state. 5. Indexed mode The Indexed mode is the index color mode, also called the ing color. In this mode, only one 8-bit color depth file can be stored, tha

vector and bitmap graphics can be masked objects or masked objects, and masked objects and masked objects can consist of multiple objects. 1. 2 Categories of Masks: There are many ways to create a mask, but the final mask has only two categories: image masks and path masks 1, Image mask: Image mask is generally in the image editing mode. You can use the bitmap drawing tool to create a matte on the canvas, or you can select a bitmap image as a mask object and a masked object, using a mask comman

A point operation is an image processing operation that determines the output grayscale value of a pixel based on the input gray value of the object's pixels.
