空域上的无参图像质量评价，非盲图像质量降噪算法等-No reference image quality assessment on airspace, non-blind image quality noise reduction algorithm

图像的基本运算主要包括图像间点对点的加、减、乘运算和图像内基于邻域操作的算法。本次实验以图像滤波为例，让学生体会图像的邻域运算。掌握平滑降噪滤波器的设计方法；能够编写中值滤波器和均值滤波器算法程序对医学图像进行滤波处理。-Image basic operations include inter-picture point of addition, subtraction, and multiplication algorithm based on neighborhood operations
