A New Edge Detection Method Based on Threshold Binarization

The most fundamental features of a digital image are the edges of objects. The edge detection method’s reliability and accuracy will affect directly on the comprehension machine vision system. Several edge detectors have been developed in the past decades as Sobel and Canny. Although no single edge detector has been developed satisfactorily enough for all applications. In this paper, a new edge...

Fingerprint Binarization using Convex Threshold

A fingerprint identification system is popular and important in biometric identification applications. Its process is composed of two stages: feature extraction and matching. Most fingerprint features include ending points and bifurcation called minutiaes. In this paper, we propose a new fingerprint binarization method based on convex threshold for effective minutiaes extraction. The proposed m...

Dynamic threshold method for scene change detection

In general, the scene change for video indexing could be detected by using an appropriate threshold. However, the single fixed threshold value used in previous researches cannot perform well for all videos equally. In this paper, we propose a dynamic threshold method(DTM) in order to improve the performance of the scene change detection. The proposed method utilizes variable parameters obtained...
