Question

我正在尝试计算图像分类功能的结果，但我一直收到无法找到某个文件的错误

f=dir('C:\Users\bla\Documents\MATLAB\Test');
countco = 0;
countfo = 0;
counthi = 0;
countic = 0;
files={f.name};
for k=3:86
  fullFileName = fullfile(files{k});
im = imread(fullFileName);
sub = image_classificationhsv(im);
if (result==Coast)
    countcoa = countcoa + 1; 
end
if (result==Forest)
    countcoa = countfo + 1; 
end
if (result==Highway)
    countcoa = countcoa + 1; 
end
if (result==City)
    countcoa = countcoa + 1; 
end
end

函数image_classification hsv code

function [class] = image_classificationhsv(image1)
f=dir('C:\Users\bla\Documents\MATLAB\Train');
files={f.name};
for k=1:numel(files)
fullFileName = fullfile(files{k});
cellArrayOfImages{k}=imread(fullFileName);
end

我一直收到错误：

 Error using ==> imread at 372
 File "coast_arnat59.jpg" does not exist.

 Error in ==> image_classificationhsv at 7
    cellArrayOfImages{k}=imread(fullFileName);

Answer 1

读取文件时需要添加路径。最简单的方法是将字符串与[]连接起来。

p = 'C:\Users\bla\Documents\MATLAB\Test\'
f = dir([p,'*.jpg']); % jpg files in directory

然后：

fname = [p, files{k}]; % path + file name
yourcellarray{k} = imread(fname);

在Matlab中比较来自2个不同文件的图像
