Description: A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind of texture features, are extracted from three different sizes of Region of Interest (ROI) areas based on the reference point from the enhanced fingerprint image. Each set of invariant moments contain seven invariant moments. Fingerprint verification is realized by Euclidean distance between the two corresponding features of the test fingerprint image and template fingerprint image in the database. -A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed.

Description: Tutorial GUI to demonstrate basic functionality of various controls on the GUI-This GUI will help the novice user get up to speed very quickly on using GUI-based applications. Everything is laid out in a very simple Step 1, Step 2, Step 3, etc. layout. It is a very good starting point for a typical image analysis application. This application uses GUIDE to do the user interface design, and has most of the basic controls such as buttons, listboxes, checkboxes, radio buttons, scrollbars, etc. It allows the user to select a folder of images, select one or more images and display them, to select a series of options, and to individually or batch process one or more images. The user can optionally apply a mask (region of interest) to the image so that only the area within the mask will be analyzed. The results are optionally sent to Excel. In this demo, I do some very basic particle sizing but in use, the user would replace that simple demo code in the function AnalyzeSingleImage() with their own code. Works with Windows or Unix since paths are all forward slashes. Req Platform: |

Description: Lip image analysis has attracted much interest in
recent years because some important speech information is
contained in the shape and movement of the lip. To extract
such information from the lip images, accurate and robust
lip region segmentation is of vital importance. However,
most of the current lip segmentation methods fail to provide
accurate results if the person has beards. Platform: |

Description: SPLITMERGE Segment an image using a split-and-merge algorithm.
G = SPLITMERGE(F, MINDIM, @PREDICATE) segments image F by using a
split-and-merge approach based on quadtree decomposition. MINDIM
(a positive integer power of 2) specifies the minimum dimension
of the quadtree regions (subimages) allowed. If necessary, the
program pads the input image with zeros to the nearest square
size that is an integer power of 2. This guarantees that the
algorithm used in the quadtree decomposition will be able to
split the image down to blocks of size 1-by-1. The result is
cropped back to the original size of the input image. In the
output, G, each connected region is labeled with a different
integer. - SPLITMERGE Segment an image using a split-and-merge algorithm.
