Give a single intensity transformation function for spreading the intensities of an image so the lowest intensity is 0 and the highest is L-1. 为了扩展一幅图像的灰度，使其最低灰度为0、最高灰度为L-1，请给出一个单调的变换函数。Answer: Let f denote the original image. First subtract the minimum value of f denoted fmin from f to yield a function whose minimum value is 0:Next divide g1 by its maximum value to yield a function in the range 0,1 and multiply the result by L一1 to yield a function with values i
