hello, So i am having trouble making images the same dimensions. I have a library of images and i need help accomplishing this.
i would like to search for the image with the biggest dimensions then have the other images form to that.
i tried useing
imresize(img(i),[376 292], 'bilinear')
just using a base row col but not all of them became the same

Should have worked, as long as you're not really using img(i) (a scalar) to index your images. I assume you mean img{i}, if holding them in a cell array, or something along those lines.

Inside the loop you just check the size of each image
[rows, columns, numberOfColorChannels] = size(theImage);
if rows > mostRows
mostRows = rows;
if columns > mostColumns
mostColumns = columns
Then do the loop again but call imresize() inside the loop
theImage = imresize(theImage, [mostRows, mostColumns]);
You can save it with the new size if you want, or just process it in the loop with whatever operations you want to do on it.

Undefined function or variable 'mostRows'.

You should know the max number of rows that your images have. So just assign that variable to that number. You can find out in many ways, such as with a MATLAB script, or simply by looking at your images in File Explorer and see what it says the sizes are.
