Display 2-D Images
The toolbox provides several functions for viewing image data. To understand all the toolbox image display capabilities, see Choose Approach to Display 2-D and 3-D Images.
Use the Image Viewer app to view and explore images. Image Viewer includes tools that you can use to examine image pixels in detail, crop an image, adjust image contrast, apply colormaps, and measure distances between pixels or areas of polygon regions. For more information, see Get Started with Image Viewer App.

Topics
Display Images in a Figure Window
- Display an Image in Figure Window
Display grayscale, RGB, indexed, and binary images in a figure window. - Display Multiple Images
Display multiple images in separate figure windows or individually in the same figure window. You can also create a composite of two images for easier comparison. - Display Different Image Types
Display truecolor, grayscale, binary, and indexed images in a figure window or in the interactive Image Viewer app. - Display and Explore Blocked Images
This example shows how to visualize and explore large and multiresolution images stored asblockedImageobjects. (Since R2024b) - Print Images
Print images to use them in a word processing program or graphics editor. - Manage Display Settings
View and edit settings to control how images are displayed on your screen by default.
Explore and Interact with Images
- Get Started with Image Viewer App
Display, explore, and process images interactively with Image Viewer app. - Get Pixel Information in Image Viewer App
Display information about the location and value of individual pixels or view neighborhoods of pixel values. - Crop Image Using Image Viewer App
Extract, or crop, a rectangular region of the image. You can fine tune the size and position of the crop region. - Measure Distances and Areas Using Image Viewer App
Measure the length of a line segment drawn between two pixels or the area within a drawn polygon. - Adjust Image Contrast in Image Viewer App
Adjust image contrast and brightness by using the Adjust Contrast tool or the Window/Level tool.
Display Image Sequences
- View Image Sequences in Video Viewer
Animate image sequences using the Video Viewer app. Explore the image sequence with playback, panning, and zooming controls. - Convert Multiframe Image to Movie
Create a movie from an image sequence of truecolor or indexed images. Movies can be played in the MATLAB® environment or written to a video file.
Featured Examples
Add Color Bar to Displayed Grayscale Image
Display a grayscale image with a color bar that indicates the mapping of data values to colors. Seeing the correspondence between data values and the colors displayed by using a color bar is especially useful if you are displaying unconventional range data as an image.
View and Edit Collection of Images in Folder or Datastore
Use the Image Browser app to view a collection of images, inspect and select images to send to another app, and export a subset of the collection to an image datastore.
