我们经常用的main函数都是不带参数的.因此main 后的括号都是空括号.实际上,main函数可以带参数,这个参数可以认为是 main函数的形式参数.C语言规定main函数的参数只能有两个, 习惯上这两个参数写为argc和argv.因此,main函数的函数头可写为: main (argc,argv)C语言还规定argc(第一个形参)必须是整型变量,argv( 第二个形参)必须是指向字符串的指针数组.加上形参说明后,main函数的函数头应写为: main (argc,argv) int argv;…

人的视觉系统具有颜色恒常性,能从变化的光照环境和成像条件下获取物体表面颜色的不变特性,但成像设备不具有这样的调节功能, 不同的光照环境会导致采集的图像颜色与真实颜色存在一定程度的偏差,需要选择合适的颜色平衡(校正)算法,消除光照环境对颜 色显现的影响.灰度世界算法是最常用平衡算法. 一.灰度世界算法 灰度世界算法以灰度世界假设为基础,该假设认为:对于一幅有着大量色彩变化的图像,,三个分量的平均值趋于同一灰 度值.从物理意义上讲,灰色世界法假设自然界景物对于光线的平均反射的均值在总体上是个定值,这…
