In this paper we propose a novel edge based, fast and effective stereo matching method, which utilises various geometrical and local area constraints and structural information among edge segments to
以粮虫检测系统中图像的预处理环节为研究对象 ,讨论分析了对比度扩展增强算法、邻域平滑算法以及中值滤波算法 ,得出对比度扩展增强可以扩大目标灰度的动态范围 ,邻域平滑对消除随机噪声效果较好 ,而中值滤波则对去除脉冲噪声很有效 ,并给出了具体的应用实例 .由实验结果可以看出 ,所选算法能够完成系统图像预处理的任务 .
图形图像文件大致上可以分为两大类:一类为矢量图形,是根据几何特性来绘制的图形图像。这类图像的表达细致、真实,缩放后图形图像的分辨率不变,在专业级的图形图像处理中应用较多。一类为位图文件,以点阵形式描述图形图像,是我们平常接触较多的图像文件。 JPEG(Joint PhotoGraphic Experts Group,联合图像专家组):主要用于静止图像压缩的位图文件格式,支持24位颜色,最大图像像素
