嵌入式图像系统的Bresenham反走样算法的应用

　　为了提高在嵌入式图像处理系统中低分辨率环境下的图像显示效果和算法的效率，对区域Bresenham反走样算法进行改进，将变换的直线扫描转换算法与区域反走样算法相结合，提高了反走样直线的绘制速度和程序执行的效率。将改进的算法应用到实际的嵌入式图像系统中验证，结果表明，引入的改进算法的效率提高了1倍左右并且明显改善了图像的显示效果。

　　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.
