灰度图像的量化和直方图均衡化直接调用函数。量化是指将像素灰度转换成离散的整数值的过程。量化等级越多，所得图像层次越丰富，灰度分辨率高，图像质量好，但数据量大。-Write MATLAB functions to quantize grayscale image with given quantization step Q.
Process the given test images “Lena” with quantization steps Q=2, 4, 8 16, 32, 64, 128.
Calculate the MSE for the original and quantized images using MATLAB methods written for
the Task 1. Plot the MSE for the test image as a function of quantization step Q.
Show quantized images and the corresponding histograms for each quantization step Q. Show
the test image and its histogram.
