光学领域，基于Matlab编写的图像生成演示程序，可生成菲涅尔衍射中的圆孔衍射图样，并进行了多个参数的模拟对比，彩色图样更加清晰。-Optics, image generation based on Matlab prepared demo program can generate Fresnel diffraction diffraction pattern of the hole and make a simulated comparison of multiple parameters,

This code is able to find the gait energy image of a person. I used casia for this. In the walking process, the human body shows regular periodic motion, especially upper and lower limbs, which reflect the individual’s unique movement pattern. Human

数字图像处理：（1）输入图像，采用半色调技术并将图像打印和显示。（2）按要求降低图像的灰度级。（3）采用像素复制的方法对图像进行缩放。（4）采用双线性插值法的方法对图像进行缩放。-Image Printing Program Based on Halftoning The following figure shows ten shades of gray approximated by dot patterns. Each gray level is represented by a 3
