imageprocessing6
1.选择一幅图像,对该图像进行DCT块操作(将图像分成8×8小块,对每个小块进行DCT变换)。
2.利用屏蔽矩阵对DCT系数进行区域选择,然后进行逆变换(IDCT),合成原图像,计算合成图像的PSNR。
3.选择一小波函数,对一幅图像进行分解,显示各变换系数,观察其规律,并进行小波逆变换,合成原图像。
(1. Select an image, the image DCT block operations (the image is divided into 8 × 8 small pieces of each small piece for DCT transform). 2. The use of shielding on the DCT coefficient matrix of regional choices, and then inverse transform (IDCT), synthesis of the original image, calculating the synthetic image PSNR. 3. To select a wavelet function, decomposition of an image to show the transform coefficients, to observe its laws, and inverse wavelet transform, the original synthetic image.)
