Compatibility Considerations The Image Processing Toolbox software now requires the following new directory on the MATLAB path: toolbox\shared\imageslib 51 Image Processing ToolboxTM Release Notes Version 5. 0. 1 (R14SP1) Image Processing Toolbox This table summarizes what's new in Version 5. 0. 1 (R14SP1). New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Bug fixes Details Related Documentation at Web Site No Major Bug Fixes The following are major bug fixes in this release. DCT Image Compression Demo Now Calculates Mean Squared Error Correctly The 2-D DCT Image Compression demo (dctdemo) previously calculated the mean squared error incorrectly. Choose Colormap Tool Now Works with Compiled Applications The Choose Colormap tool now saves the colormap selection when running in a compiled version of the Image Tool. Image in Pixel Region Tool Now Updates When Using the Adjust Contrast Tool Previously, if you used imtool to display a grayscale image, launched the Pixel Region tool, and then used the Adjust Contrast tool to adjust the contrast of the image, the pixel colors in the Pixel Region tool did not update properly. This has been fixed. 52 Version 5. 0 (R14) Image Processing ToolboxTM Version 5. 0 (R14) Image Processing Toolbox This table summarizes what's new in Version 5. 0 (R14SP2): New Features and Changes Yes Details below Version Compatibility Considerations Yes--Details labeled as Compatibility Considerations, below.

The Image Tool replaces the Image Viewer, providing all the display and exploration capabilities of its predecessor. For example, you can use the Image Tool to display an image, view general information about the image, get information about individual pixels or regions of pixels in the image, and navigate large images using the Overview navigation window, scroll bars, and magnification tools. In addition, the Image Tool introduces several new tools, such as the Adjust Contrast tool and the Choose Colormap tool. You can use the Adjust Contrast tool to adjust the brightness and contrast of an image interactively. You can use the Choose Colormap tool to change the colormap for indexed and intensity images to any of MATLAB colormaps or to a user-defined colormap. Unlike the Image Viewer, the Image Tool is built using standard features of MATLAB Handle Graphics®. This enables the Image Tool to provide access to the image being displayed using standard Handle Graphics techniques. For example, you can use annotations and overlay vector graphics on images displayed in the Image Tool. You can use imtool as an example to follow or as a base to use to create your own application. To start the Image Tool, use the imtool function: imtool('moon. tif') New Modular Interactive Tools The toolbox includes several new modular interactive tools that you can activate from the command line and use with images displayed in a MATLAB figure window, called the target image in this documentation. The tools are modular because they can be used independently or in combination to create 54 Version 5. 0 (R14) Image Processing ToolboxTM custom graphical interfaces for image processing applications. The Image Tool uses these modular tools. The following table lists these modular tools along with the functions you use to create them. Modular Tool Adjust Contrast tool Description Display histogram of image pixel values in the target image and enable interactive adjustment of contrast and brightness by manipulating the range. Display a text string identifying the display range values of the target image. Display basic information about an image, along with any metadata the image might contain. Function Use imcontrast to create the tool in a separate figure window and associate it with an image. Display Range tool Use imdisplayrange to create the tool, associate it with an image, and embed it in a figure or uipanel. To collect image information, use imattributes, imfinfo, and dicominfo. Image Information tool 55 Image Processing ToolboxTM Release Notes Modular Tool Magnification box Description Create a text edit box containing the current magnification of the target image.
