嵌入式圖像系統(tǒng)的Bresenham反走樣算法的應(yīng)用

　　為了提高在嵌入式圖像處理系統(tǒng)中低分辨率環(huán)境下的圖像顯示效果和算法的效率，對(duì)區(qū)域Bresenham反走樣算法進(jìn)行改進(jìn)，將變換的直線掃描轉(zhuǎn)換算法與區(qū)域反走樣算法相結(jié)合，提高了反走樣直線的繪制速度和程序執(zhí)行的效率。將改進(jìn)的算法應(yīng)用到實(shí)際的嵌入式圖像系統(tǒng)中驗(yàn)證，結(jié)果表明，引入的改進(jìn)算法的效率提高了1倍左右并且明顯改善了圖像的顯示效果。

　　Abstract:

　　In order to enhance display effect and the algorithm efficiency in the embedded image processing system under the low resolution environment， the improvement of the region Bresenham algorithm was made， which combined and transformed linear scanning transformation algorithm with area Bresenham anti-aliasing algorithm， enhanced the speed of drawing straight line plan and the program execution efficiency. The improvement algorithm was applied in the actual embedded system to confirmation. The result indicated that the efficiency of the introduced improved improvement algorithm is enhanced about 1 time and the image demonstration effect was improved obviously.
