Error: subscripted assignment dimension mismatch for loop

Hello,

The error I get is :

for i = 1:numTraining mhi_fig = sprintf('data%d.png', i); img(i,:)=imread(mhi_fig); end Why does this happen? and what is the solution?

The error occurs because you try to assign an image (2D) to a row (1D) img(i,:).

You can use

img{i} = imread(mhi_fig);

or, if the images have all the same size

img(:,:,i) = imread(mhi_fig);  % for gray scale images
img(:,:,:,i) = imread(mhi_fig); % for color images
