フィルターのクリア

why am I getting an error for this tutorial when adapted to my image? how can I fix this error:

clear; % Delete all variables.
close all; % Close all figure windows except those created by imtool.
% imtool close all; % Close all figure windows created by imtool.

lab_fabric = rgb2lab('image.tif');
a = lab_fabric(:,:,2);
b = lab_fabric(:,:,3);
color_markers = zeros([nColors, 2]);
for count = 1:nColors
color_markers(count,1) = mean2(a(sample_regions(:,:,count)));
color_markers(count,2) = mean2(b(sample_regions(:,:,count)));
end
color_labels = 0:nColors-1;
a = double(a);
b = double(b);
distance = zeros([size(a), nColors]);
for count = 1:nColors
distance(:,:,count) = ( (a - color_markers(count,1)).^2 + ...
(b - color_markers(count,2)).^2 ).^0.5;
end
[~,label] = min(distance,[],3);
label = color_labels(label);
clear distance;
rgb_label = repmat(label,[1 1 3]);
segmented_images = zeros([size(fabric), nColors],'uint8');
for count = 1:nColors
color = fabric;
color(rgb_label ~= color_labels(count)) = 0;
segmented_images(:,:,:,count) = color;
end
montage({segmented_images(:,:,:,2),segmented_images(:,:,:,3) ...
segmented_images(:,:,:,4),segmented_images(:,:,:,5) ...

Then you forgot to import the image, start with the imread function to read the image and then call rgb2lab
fabric = imread('fabric.png');
lab_fabric = rgb2lab(fabric);

Very few image related functions accept file names. imread() does if course, and imshow() does as well. I seem to recall that one of the image montage functions accepts file names. Some of the image information functions as well. But for anything other than imread you should always check the documentation to be sure that it accepts file names. It is safer to assume that most functions require that you pass in image data rather than file names.
