matlab读取未知格式图像

fid=fopen('*.prj,'r');
fseek(fid,8369,'bof');              %跳过header,一共8369个byte
temp = fread(fid,[80,80],'float32');    %reshape 80*80 矩阵
temp=temp';
% image= mat2gray(temp);
image=temp;

批量读取

files = dir([directory_name,'\*.prj']);   %<<========找到目录中的所有.prj文件

for n=1:numel(files)
    fid=fopen([directory_name,'\',...
          files(n).name],'r');
fseek(fid,8369,'bof'); %skip the header
temp = fread(fid,[80,80],'float32');
temp=temp';
% image{n}= mat2gray(temp);
image{n}=temp;
fclose(fid)
end
