This paper describes a new approach for tracking circular traffic signs from image sequences. As a part of traffic sign recognition system, the traffic sign tracking will improve the performance of the recognition. By tracking the signs, search space is reduced and misdetection caused by temporal occlusion could be avoided. We propose a new blob tracking called two-layer blob tracking to track ...

This paper presents an active vision system for realtime traffic sign recognition. The system is composed of two cameras, one is equipped with a wide-angle lens and the other with a telephoto lens, and a PC with an image processing board. The system first detects candidates for traffic signs in the wide-angle image using color, intensity, and shape information. For each candidate, the telephoto...

BIOMETRIC FEATURES HAVE GREAT IMPORTANCE IN AUTHENTICATION SYSTEMS NOWADAYS. ONE OF THE MOST IMPORTANT AND CONVENTIONAL BIOMETRICS IS SIGNATURE. IN THIS PAPER, WE PROPOSED A SYSTEM WHICH HAS TWO INDEPENDENT PHASES FOR OFFLINE SIGNATURE IDENTIFICATION AND VERIFICATION. THE IDENTIFICATION PHASE IS BASED ON TSR (TRIANGLE SPATIAL RELATIONSHIP) THAT IS A ROTATION INVARIANT FEATURE EXTRACTION METHOD....

A robust two-stage shape retrieval (TSR) method is proposed to address the 2D shape retrieval problem. Most state-of-the-art shape retrieval methods are based on local features matching and ranking. Their retrieval performance is not robust since they may retrieve globally dissimilar shapes in high ranks. To overcome this challenge, we decompose the decision process into two stages. In the firs...

For decades the German economy was bank centered and stakeholder oriented. Inherent to the system the capital market did not play a central role. Since the 1990s the German economy has undergone some fundamental changes. The old ‘Germany Inc.’ is in the progress of disintegration. With an increasing capital market orientation, the venture capital and IPO market almost gained ground automaticall...
