MATLAB: Somebody help me out the following code is throwing some error

this is the code
    clc;
    clear all;
    imdataPositive={};
    imgPath = 'D:\EDU\Project\Images\';
    dCell = dir([imgPath '*.jpg']);
    for a=1:length(dCell)
        baseFileName = dCell(a).name;
        fullFileName = fullfile(imgPath, baseFileName);
        imdataPositive{a} =imread(fullFileName);
    end
    %for a=1:length(dCell)
    %imageNames = {imdataPositive{a}};
    %end
    numImages = numel(imdataPositive);
    emptyEntry = struct('image',[],'thumbnail',[]);
    imageCollection = repmat(emptyEntry,[1 numImages]);
    thumbnailSize = 400;
    for i = 1:numel(imageCollection)
        imageCollection(i).image = imread(imdataPositive{i});
        imageCollection(i).thumbnail = imresize(imageCollection(i).image,...
            [thumbnailSize,thumbnailSize]);
    end
    figure;
    montage(cat(4,imageCollection.thumbnail));
    title('Image Collection');
this is the error
    ??? Error using ==> strfind
    Input strings must have one row.
    Error in ==> imread at 329
    if (strfind(filename, '://'))
    Error in ==> test2 at 19
        imageCollection(i).image = imread(imdataPositive{i});

Best Answer

Sai - I think that you are trying to do too many imreads. Note that you initialize imdataPositive as
 for a=1:length(dCell)
        baseFileName = dCell(a).name;
        fullFileName = fullfile(imgPath, baseFileName);
        imdataPositive{a} =imread(fullFileName);   
 end
where each element of imdataPositive is an image. Later in the code (at line 19), you try to do
 imageCollection(i).image = imread(imdataPositive{i});
But imdataPositive{i} is already an image! All that you have to do is replace the above
 imageCollection(i).image = imdataPositive{i};
Try the above and see what happens!
