如何将图像传输到位并返回MATLAB

Question

我正在尝试传输小 .jpg 图。我正在使用以下行将图片转换为位：

pic = imread('****.jpg');
x = reshape((dec2bin(typecast(pic(:),'uint8'),8)-'0').',1,[]);

然后，我正在尝试以下来重建图像：

n = 250;
m = 250;
s = num2cell(reshape(x,8,[])',2);
b = cellfun(@(x) bin2dec(strrep(num2str(x),' ','')), s);
out = reshape(b,n,m);  

我收到此错误消息：

Error using reshape
To RESHAPE the number of elements must not change.
Error in transmit_pic (line 13)
out = reshape(b,n,m);

我在做什么错？

Answer 1

修补一点后，我找到了解决方法。问题是位深度。

这是正确的代码：

pic = imread('***.png');
x = reshape((dec2bin(pic,8)-'0').',1,[]);
[m, n] = size(pic);
s = num2cell(reshape(x,8,[])',2);
b = cellfun(@(x) bin2dec(strrep(num2str(x),' ','')), s);
out=reshape(b,m,n);  
image(out)
