解釋
仿射比-
On the basis of the new affine transformation and self - adapted quadtree im - age compression method, we bring forward a new image compression method. experiments show that the psnr can reach 28. 7db at the compression ratio of 22. 4 for 256 x 256 x 8 " lena " image, better than jacquin [ 1 ], fisher [ 13 ] and yao zhao [ 12 ] ' s method. at last, we point out the defects of the method and program, bring forward some ways to be improved
並介紹了用此演算法編寫的程序,給出了實驗結果,實驗結果顯示「 lena 」 256 256 8圖象在psnr等於28 . 7時,壓縮比可以達到22 . 4 ,比fisher , jacquin ,和趙耀等人的結果都有一定程度的改進,文章最後指出了演算法和程序的不足,提出了一些改進的方向。
