How can I read a set of images in a 1x6 cell array?

How can I use the imread function ro read a set of images that is in a 1x6 cell array format?

[Walter Roberson]

nfiles = length(YourCellArray);
image_content = cell(nfiles,1);
for K = 1 : nfiles
    image_content{K} = imread(YourCellArray{K});
end

Or more simply,

image_content = cellfun(@imread, YourCellArray, 'uniform', 0);

Not sure what you're doing. nfiles is the number of crossing points in that particular image, not the number of files. So let's say you had 5 files and the number of crossing points was 10, 20, 30, 40, and 50. Then what are you hoping to do by creating this cell array image_content? Let's take a look at image #3 with its 30 crossing points. So you're creating a cell array of 30 subimages that are each just a 5-by-5 box around each crossing point. Essentially each of the 30 is just a black box with a white dot in the center. What's the point of that?

for example, for One image, i have vector 1*17 from each neghbor( 5*5 window):

(x1()-2:x1()+2,y1()-2:y1()+2)

Of curse, number of special point for other image mybe 5,12, 3,...

Above output, the determined neighbor from one image. I attempt to apply for this code on many images with different numbers of special points.

nfiles is the length of the cell array x1. If you did not initialize x1 and there are no leftover x1 values from a previous run then the length of x1 will be the same as the value of i, the file number being processed. It will not be the number of crossovers detected in the current signal.

I cant correct this line... , i detemineed x1 in line 8

imagepath='MiniDB';
% Savepath='miniDBThin';
filelist=dir(fullfile(imagepath,'*.jpg'));
filelistname={filelist.name};
for i=1:length(filelistname)
    I=im2bw(imread(fullfile(imagepath,filelistname{i})));
    skelImage{i} = bwmorph(I, 'skel', inf);
   
    nfiles = length(x1);
    image_content = cell(nfiles,1);
    for K = 1 : length(x1)
     image_content{K}=skelImage(x1(K)-2:x1(K)+2,y1(K)-2:y1(K)+2);

    end
end

[Walter Roberson]

    nfiles = length(x1{i} );
    image_content = cell(nfiles,1);
    for K = 1 : length(x1)
     image_content{K} = skelImage(x1{i}(K)-2:x1{i}(K)+2, y1{i}(K)-2:y1{i}(K)+2);
    end

I recive this error:

Index exceeds matrix dimensions.

[Walter Roberson]

You deleted the code showing how x1 and y1 are created.

We can deduce from the error message that at least one of the x1{i} or y1{i} values is either 1 or 2, or else the last possible value or the last minus 1. Under those circumstances subtracting 2 or adding 2 could be out of range.
