How to get images of specified width and height/ resize them to specified width and height?

How to get images of specified width and height/ resize them to specified width and height?

I am processing a large data set and want to prepare an animation out of it. But the images have different frame sizes, like: 2850 x 780; 2803 x780; 2849 x 780?

Is there any function avaiable to specify the frame size?

Thanks in advance.

Use function imresize

It does not have option for specifying the size.

Try imresize()

desiredRows = 512;
desiredColumns = 1000;
resizedImage = imresize(originalImage, [desiredRows, desiredColumns]);
% double check
[rows, columns, numberOfColorChannels] = size(resizedImage)

[Prashant Pathak]

row= 1 and column=1 for each image

but width and height come different for each image.

What does that mean? I didn't compute row and column. And even if your images are only one pixel (1 row and 1 column), imresize() should work. Or if you want desiredRows to be 1, and desiredColumns to be 1, it should still work. Explain using a lot more words this time, because I already know your images are of different sized -- you said that already.

@Prashant Pathak, did this work?
