Image Processing Toolbox 6.4

Displaying and Exploring Images and Video

Image Processing Toolbox provides a suite of tools for interactive image display and exploration. You can load an image from a file or from the MATLAB workspace, view image information, adjust the contrast, closely examine a region of pixels, and zoom and pan around the image. You can interactively place and manipulate ROIs, including points, lines, rectangles, polygons, ellipses, and freehand shapes. You can also interactively crop, create histograms and contours, and measure distances.

The Pixel Region window superimposes pixel values on a highly magnified view. LANDSAT image of Paris courtesy of Space Imaging, LLC. Click on image to see enlarged view.

The toolbox includes tools for displaying video and sequences in either a time-lapsed video viewer or image montage. Volume visualization tools in MATLAB let you create isosurface displays of multidimensional image data sets.
