請(qǐng)教各位高手, 在看文獻(xiàn)的時(shí)候注意到圖像壓縮的時(shí)候有一個(gè)單位是bpp,bit per pixel。但在圖像JPEG,和JPEG2000中應(yīng)該怎么實(shí)現(xiàn)bpp的計(jì)算?? 希望高手指點(diǎn)~~ |

| In computer graphics, color depth or bit depth is the number of bits used to indicate the color of a single pixel in a bitmapped image or video frame buffer. This concept is also known as bits per pixel (bpp), particularly when specified along with the number of bits used. Higher color depth gives a broader range of distinct colors. |
