  • 摘要: 為了提高圖像的壓縮比和壓縮質(zhì)量,結(jié)合人眼對(duì)比度敏感視覺特性和圖像變換域頻譜特征,該文提出一種自適應(yīng)量化表的構(gòu)建方法。并將該表代替JPEG中的量化表,且按照J(rèn)PEG的編碼算法對(duì)3幅不同的彩色圖像進(jìn)行了壓縮仿真實(shí)驗(yàn)驗(yàn)證,同時(shí)與JPEG壓縮作對(duì)比分析。實(shí)驗(yàn)結(jié)果表明:與JPEG壓縮方法相比,在相同的壓縮比下,采用自適應(yīng)量化壓縮后,3幅解壓彩色圖像的SSIM和PSNR值分別平均提高了1.67%和4.96%。表明該文提出的結(jié)合人眼視覺特性的自適應(yīng)量化是一種較好的、有實(shí)用價(jià)值的量化方法。
