In this article, we propose a new extension to a Dynamic Programming Algorithm (DPA) approach for Track-beforeDetect challenges. This extension enables the DPA to process time-delayed sensor data directly. Such delay might appear because of delays in communication networks. The extended DPA is identical to the recursive standard DPA in case of all sensor data appear in the timely correct order....

This paper presents a method forfinding and tracking road lanes. The method extracts and tracks lane boundaries for vision-guided vehicle navigation by combining the hough transform and the “active line model ( A M ) ” . The hough transform can extract vanishing points of the road, which can be used as a good estimation of the vehicle heading. For the curved road, however, the estimation may be...

(This material was originally intended as part of the article “The Loudness War: Background, Speculation and Recommendations” [1] but was removed for reasons of scope and to keep that article to a manageable length.) In this paper, I briefly review a variety of metrics for quantifying the loudness and dynamic spread of audio recordings. This review was motivated by the need for objective ways o...

This paper addresses the problem of tracking a dim moving point target in a sequence of IR images. The proposed tracking system, based on the track-before-detect (TBD) approach, is designed to track and detect dim maneuvering targets from an image sequence under low SNR conditions; a dynamic programming algorithm (DPA) is used to process the frames in the sequence. This paper deals with the pra...
