1-1、图象的灰度变换
对图象p1-03实施灰度平方根变换
1，　　要求：显示变换前后2幅图象和2幅直方图，变换参数自行设定。
1-2、空域平滑
对图象p1-03施加高斯噪声和椒盐噪声并实施梯度倒数加权平滑法
要求：显示变换前后2幅图象，利用方差评价空域平滑的效果。
1-3、空间锐化
根据Sobel算子，按照公式4.3.8和公式4.3.9对图象p1-03实施空间锐化
要求：显示变换前后2幅图象。(1-1. Gray transformation of image
The square root transformation of image p1-03 was implemented
1. Requirements: show the two images and two histogram before and after the transformation, and the transformation parameters are set by themselves.
1-2. The airspace is smooth
The gaussian noise and pretzel-salt noise were applied to the image p1-03 and the gradient reciprocal weighted smoothing method was implemented
Requirements: show the two images before and after the transformation and use the variance to evaluate the smooth effect of the airspace.
1-3 space sharpen
According to Sobel operator, the space sharpening of image p1-03 was implemented according to formula 4.3.8 and formula 4.3.9
Requirements: show the two images before and after the transformation.)
