3 图像基本处理操作（图像显示、读写、像素统计处理、图像文件I/O等）

4 图像质量的客观评价（峰值信噪比PSNR及其应用）

5 图像的代数运算（绝对值差函数imabsdiff，叠加函数imadd，图像的旋转imrotate）

6 视频处理（创建AVI视频）

7 图像增强（直方图、直方图均化、均值滤波、中值滤波）

8 图像形态学分析（膨胀、腐蚀、开、闭运算、轮廓提取）

-3 basic image processing operations (image display, read and write, pixel statistics processing, image file I/O, etc.) 4 objective evaluation of image quality (PSNR peak signal to noise ratio and its application) 5 images of algebraic operations (sum of absolute differences function imabsdiff , superimposed function imadd, image rotation imrotate) 6 video processing (creating AVI video) 7 image enhancement (histogram, histogram equalization, mean filtering, median filtering) 8 image morphology analysis (expansion, erosion, opening and closing operations, contour extraction)
