good after noon everyone....
I wrote this script that must combines 3 RGB images into one image note that 1.png, 2.png and 3.png are images of same dimentions (500 x 666) I need the final image to show the three images as one image but with reasonable dimensions
Rows = 1;
Cols = 3;
Cell = cell(Rows,Cols);
for i = 1:Rows*Cols
imageName = sprintf('%i.png',i);
imgCell{i} = imread(imageName);
end
bigImage = mat2cell(imgCell);
imshow(bigImage)
However I received this error:
Error using imageDisplayValidateParams
Expected input number 1, I, to be one of these types:
double, single, uint8, uint16, uint32, uint64, int8, int16, int32, int64, logical
Instead its type was cell.
Error in imageDisplayValidateParams (line 11)
validateattributes(common_args.CData, {'numeric','logical'},...
Error in imageDisplayParseInputs (line 78)
common_args = imageDisplayValidateParams(common_args);

Error in Untitled3 (line 26)
imshow(bigImage)

What do you want to do? Do you want to average them together? Stitch them side-by-side? Have you seen montage(), imshowpair(), and imfuse()? Explain more what you want to do and I can give a more specific solution.

Because you're passing imshow() a cell array , and in each cell of the array is a chunk of an image - a sub image. imshow() wants the images themselves, directly, it doesn't want a cell array of a bunch of cells that each contain an image. A cell array is like a collection of buckets, and you can thrown whatever you want (images, strings, etc.) into any of the buckets. Please read the FAQ to get a good intuitive feel for what cell arrays are: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

You can display a cell array of images using imdisp.
imdisp(imgCell)

I think you may have not visited the link he gave to his File Exchange and downloaded the file. http://www.mathworks.com/matlabcentral/fileexchange/22387-imdisp
Or if you did, you put it somewhere not on the search path.
