1 Matlab中图像数据类型转换：MATLAB中读入图像的数据类型是uint8，但在矩阵运算中的数据类型是double；因此I2 = im2double(I1) :把图像数组uint8 类型(I1)转换成double精度类型；如果不转换，在对uint8进行加减时会产生溢出，可能提示的错误为：Function '*' is not defined for values of class &#...

% Now convert it to uint8. It will clip values outside the range 0-255, and will round values in the range. G = uint8(G); Quan Zhengon 21 Feb 2024 Hi, I have ran into a issue a bit tougher than this. Now I have a 'double' file contains water saturations with 4 decimal po...
char:Convert to character array,转换为字符数组;matlab 下没有 str 字符串类型转换; char(0-255) ⇒ ASCII 码的转换; im2double(): 将intensity image (0-255,uint8 的整型类型)转换为 0-1 的 double 类型(double precision,双精度); 0. ismatrix() ismatrix 对于三维的矩阵返回值为 logical false。...

1 输入映像可以是uint8、uint16、single、int16或double类，并且必须是不透明的。输出图像BW是类逻辑的。I和X必须是二维的。RGB图像是M乘N乘3的。Examples（示例）1 load treesBW = im2bw(X,map,0.4);imshow(X,map), figure, imshow(BW)命令行键入：load treesBW = im2bw(X,map,0.4);imshow(X,map)...
