我已将图像从RGB转换为灰度,并在uint8中具有图像矩阵.我试着用卷积来做一些图像处理,这意味着当我总结所有的东西时,我想用这些值作为int。那么,如何在Matlab中从uint8转换成int呢? 浏览4提问于2018-05-09得票数3 1回答 在javascript中将浮点值转换为uint8数组 ...
使用类型转换操作符:UInt16 number = 12345; int result = (int)number; 使用Convert类中的方法:UInt16 number = 12345; int result = Convert.ToInt32(number); 无论使用哪种方法,都可以将UInt16类型的变量转换为int类型的整数。这样做的目的是将UInt16的取值范围(0到65535)转换为int的取值范围(-2147483648...
zeros函数族中有个函数为: zeros(m, n ,... classname) ,其中classname可以取“double”, "uint8", "int8"等等(默认取double). 正因为zeros默认类型是double才导致我一开始的错误。(其实,matlab中的图像经过运算后类型都会转化为double,这样可以防止溢出,并保证精度) 在一开始,矩阵J的数据类型为double, 在进...
