denoise image by DCT denoising
1 | DenoiseDCT(im, sdn, flag_dct16x16 = FALSE)
|
im |
a grayscale image of class cimg |
sdn |
standard deviation of Gaussian white noise |
flag_dct16x16 |
flag_dct16x16 determines the size of patches. if TRUE, the size of patches is 16x16. if FALSE, the size if patches is 8x8. |
