代码说明:

  对某一标准图像进行二维Mallat小波的3级分解,获得小波高/低频系数,分别 用低频分量LL1、LL2、LL3的小波系数进行图像重建,分别计算这三种情况 和原始图像比较的PSNR。(A standard image 3 2D Mallat wavelet decomposition, wavelet high/low frequency coefficients , respectively Low frequency component LL1 , LL2, LL3 wavelet coefficients for image reconstruction, respectively, to calculate the three And compared to the original image PSNR. )

  • mandelbrot
    This guide can draw a mandelbrot figure. In default values it calculates Z=Z^2+C for 20 iterations, where Z initally equal to zero and C has the values of every pixel created by meshgrid function(built-in). although mandelbrot equation is Z=Z^2+C you can change the degree of the equation between 1 - 50. higher number in iteration, points in axes gives better results in image besides more resulting time. to zoom an area of the figure you must aproximately choose the point and then change the center values to this point values then push Show Graph button. because of this is the first version there can be any lack of usage.
