Image Processing Design Toolbox

By Dr. Harald Galda (Octum GmbH)

Image processing algorithms usually consist of many steps and even more parameters. It is desirable to be able to visualize the effects of image processing operations and their parameters and to document them in a reproducible way. Furthermore, it should be possible to analyze characteristics of regions in an image so an object of interest can be distinguished from the background.

For this purpose, a toolbox for image processing was developed. This toolbox provides functionality for reading images from and writing images to hard disk, basic image processing operations such as filtering, threshold segmentation, blob analysis, histogram calculation and color conversion. Moreover, there is a graphic tool that can display an image and makes it possible to select a pixel, a line or a rectangular region and to display characteristics like gray value profile and histogram.
