An image sequence is a collection of images related by time, such as frames in a movie, or by spatial location, such as magnetic resonance imaging (MRI) slices. Image sequences are also known as image stacks or videos.

You can store an image sequence as a multidimensional array, then display and process the sequence using toolbox functions that can operate on multidimensional arrays. You can also store an image sequence as a collection of individual image files, then process the files using the Image Batch Processor app.
