i am getting the error while reading the images

ipDir = '../Dataset/photos'; isDir = '../Dataset/sketches';
files_p = dir([ipDir '*.jpg']); files_s = dir([isDir '*.jpg']);
tmp1=imread([ipDir files_p(1).name]); Index exceeds matrix dimensions.
Error in createTrainingData_color (line 13) tmp1=imread([ipDir files_p(1).name]);

I am getting the above error. Please help me.

I am getting the error while reading the images.

Evidently the length is zero and so when you try to access index 1, it says "Index exceeds matrix dimensions." Try this more robust way:

if length(files_p) > 0
    fullFileName = fullfile(ipDir, files_p(1).name);
    tmp1=imread(fullFileName);
end

files_p = dir([ipDir '*.jpg']); files_s = dir([isDir '*.jpg']);

%Find the nubmer files and the size of images

tmp1=imread([ipDir , files_p(1).name]); nFile = numel(files_p); [nRow, nCol, nCh] = size(tmp1);

%initialize matrix for data pImg_luv = zeros(nRow,nCol,nCh, nFile); pImg_rgb = zeros(nRow,nCol,nCh, nFile);

pImg = zeros(nRow,nCol,nFile); sImg = zeros(nRow,nCol,nFile); intImg = zeros(nRow,nCol,nFile); nRowPatch = nRow-pSize(1); nColPatch = nCol- pSize(2); squareSum = zeros(nRowPatch, nColPatch, nFile);

for i=1:nFile tmp1=imread([ipDir files_p(i).name]); pImg(:,:,i)=single(rgb2gray(tmp1));

    pImg_rgb(:,:,:,i)= tmp1;
    pImg_luv(:,:,:,i)= rgb2luv(tmp1);
    intImg(:,:,i) = integralimage(pImg(:,:,i).^2);

    %IRs
    for m=1:nRowPatch
        for n=1:nColPatch

            squareSum(m,n,i)=intImg(m,n,i)+intImg(m+pSize(1)-1,n+pSize(2)-1,i)-intImg(m,n+pSize(2)-1,i)-intImg(m+pSize(1)-1,n,i);
        end
    end

    tmp2=imread([isDir files_s(i).name]);
    sImg(:,:,i)=single(tmp2);
end

this is the code if i mention yours code i got another error pl check he code if possible

Now you've totally confused us. You've accepted the answer but then you've posted chunks of code in three different locations and say it's not solved. Please clarify. Edit or delete your other posts so you just have one response to me in one place.

function [pImg, pImg_rgb, sImg] = ... createTrainingData_color(ipDir, isDir, opFile, pSize)

addpath('utils/');

%ipDir='../Dataset/photos/'; %isDir='../Dataset/photos/';

files_p = dir([ipDir '*.jpg']); files_s = dir([isDir '*.jpg']);

%Find the nubmer files and the size of images

tmp1=imread([ipDir , files_p(1).name]); nFile = numel(files_p); [nRow, nCol, nCh] = size(tmp1);

%initialize matrix for data pImg_luv = zeros(nRow,nCol,nCh, nFile); pImg_rgb = zeros(nRow,nCol,nCh, nFile);

pImg = zeros(nRow,nCol,nFile); sImg = zeros(nRow,nCol,nFile); intImg = zeros(nRow,nCol,nFile); nRowPatch = nRow-pSize(1); nColPatch = nCol- pSize(2); squareSum = zeros(nRowPatch, nColPatch, nFile);

for i=1:nFile tmp1=imread([ipDir files_p(i).name]); pImg(:,:,i)=single(rgb2gray(tmp1));

    pImg_rgb(:,:,:,i)= tmp1;
    pImg_luv(:,:,:,i)= rgb2luv(tmp1);
    intImg(:,:,i) = integralimage(pImg(:,:,i).^2);

    %IRs
    for m=1:nRowPatch
        for n=1:nColPatch

            squareSum(m,n,i)=intImg(m,n,i)+intImg(m+pSize(1)-1,n+pSize(2)-1,i)-intImg(m,n+pSize(2)-1,i)-intImg(m+pSize(1)-1,n,i);
        end
    end

    tmp2=imread([isDir files_s(i).name]);
    sImg(:,:,i)=single(tmp2);
end

save(opFile, 'pImg', 'pImg_rgb', 'pImg_luv', 'squareSum', 'sImg', 'files_p', 'files_s');

this is the actual code i got the problem while reading the imaage by using imread(); pl help me
