沃尔什（Walsh）变换是一种可分离变换，广泛应用于图像处理。本代码实现了图像Walsh变换，非常经典，带图片可测试.-Walsh (Walsh) is a separable transform transform, which are widely used in image processing. Implementation of the code of the image Walsh transform, very classic, with pictures can be tested.

相机中都需要进行伽马校正，本实验中通过程序caculate_curve.m读入图片0中的灰度值，通过计算得到伽马变换的伽马系数，然后利用伽马系数进行反变换。-Both the need for gamma camera calibration, the experimental procedure caculate_curve.m read into the picture through the gray value of 0, obtained by calculating the gamma-gamma transform coefficients, then use the gamma coefficient inverse transform.
