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.
