方法/步骤 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...
% Now convert it to uint8. It will clip values outside the range 0-255, and will round values in the range. G = uint8(G); 4 Comments Show 2 older comments Quan Zhengon 21 Feb 2024 Hi, I have ran into a issue a bit tougher than this. Now I have a 'double' file contains ...
