Image Display in a Figure Window

Image Display and Exploration Overview

The toolbox automatically sets the properties of graphics objects to optimize image display.

Display an Image in a Figure Window

You can display grayscale, RGB, indexed, and binary images in a figure window. Each element of image data is displayed on a single screen pixel.

Display Multiple Images

You can display multiple images in separate figure windows or individually in the same figure window. You can create a composite of two images for easier comparison.

Display Different Image Types

You can display truecolor, grayscale, binary, and indexed images in a figure window or in the interactive Image Viewer app.

Add Colorbar to Displayed Image

A color bar shows the correspondence between data values and the colors displayed in a figure.

Print Images

Print images to use them in a word processing program or graphics editor.

Manage Display Preferences

You can view and edit preferences to control how images are displayed on your screen by default.

Interactive Image Display

Interact with Images Using Image Viewer App

You can display, explore, and process images interactively with Image Viewer app.

View Thumbnails of Images in Folder or Datastore

You can view reduced-size versions, called thumbnails, of all images in a folder using the Image Browser app. Preview images and open them directly in other apps.

View Image Sequences in Video Viewer App

You can animate image sequences using the Video Viewer app. Explore the image sequence with playback, panning, and zooming controls.

Convert Multiframe Image to Movie

You can 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.

Explore 3-D Volumetric Data with Volume Viewer App

You can view perpendicular cross-sections of 3-D volumetric data using the Volume Viewer app. Adjust the rendering to reveal structures within the volume.

Explore 3-D Labeled Volumetric Data with Volume Viewer App

You can view 3-D labeled volumetric data using the Volume Viewer app. You can view the volume and the labeled volume simultaneously and change the opacity and colormap.
