This toolbox provides functions for designing and parameterizing image processing algorithms. The following functionality is provided:

1. Histogram calculation

   • gray level histogram
   • cumulated histogram

2. Thresholding

   • segmentation by threshold
   • threshold calculation by Otsu method

3. Morphological filters

   • dilation
   • erosion
   • closing
   • opening
   • top hat
   • bottom hat

4. Median filter

5. Filtering for edge detection

   • Sobel filter
   • Laplace filter
   • Prewitt filter
   • Scharr filter

6. Region based segmentation

   • distance transform
   • watershed transform

7. Blob analysis

   • searching connected regions in binary images
   • removing blobs that have less pixels than a lower bound or more pixels than an upper bound
   • calculating specific properties of blobs such as bounding box, centroid
   • drawing bounding boxes around objects found in an image
   • calculating histogram of blob sizes
   • calculating cumulated histogram of blob sizes

8. Displaying images in figure windows

   • display
   • conversion of RGB to indexed images
   • conversion of indexed images to RGB

9. Conversion between color images and gray level images

   • RGB to gray level
   • RGB to Lab*
   • Lab* to RGB

10. Opening image and video files

    • reading image files
    • writing image files
    • reading video files

11. Linear filteration

12. Variance filter

13. Texture feature calculation

    • Laws texture energy
    • discrete Wavelet frames

14. Template Matching

15. Interactive Image Analysis GUI

Differences between versions 8.3 and 8.2:

• The toolbox can now be built on Linux and MacOS.
• OpenCV 2.1 is replaced by OpenCV 2.31.
• Blink effect that occurred when displaying video is removed.
• The toolbox will be compatible to Scilab 5.4.

This version uses OpenCV 2.31 which is available for download at
