给定m行n列的图像各像素点的灰度值,要求用如下方法对其进行模糊化处理: 1.四周最外侧的像素点灰度值不变; 2.中间各像素点新灰度值为该像素点及其上下左右相邻四个像素点原灰度值的平均(舍入到最接近的整数)。

Static electricity is the most ancient form of electricity known to humans. More than 2000 years ago, the Greeks recognized the attraction between certain mate- rials when they were rubbed together; indeed, the word electricity comes from the Greek elektron, which means amber. During the seventeenth and eighteenth centuries, several key experiments were conducted to understand and measure static electricity. But the discovery of electromagnetism and its formidable break- through has rapidly outgrown interest in static electricity. Even today, where the industrial applications of static electricity are not insignificant, they cannot compare with those of electromagnetism and electrodynamics.
