Neighbor finding is an important and a basic part of image processing in quadtrees. A constant time algorithm is proposed for neighbor finding in quadtrees in [1]. In this paper, empirical tests are given for the constant time algorithm in comparison with usual neighbor finding algorithm using quadtrees [2] and another constant time algorithm using linear(More)
In wearable computing environments, digitization of personal experiences will be made possible by continuous recordings using a wearable video camera. This could lead tothèàutomatic life-log application''. However, it is evident that the resulting amount of video content will be enormous. Accordingly, to retrieve and browse desired scenes, a vast quantity(More)
Image processing can be broadly defined as the manipulation of signals which are inherently multidimensional. The most common such signals are photographs and video sequences. The goals of processing or manipulation can be (i) compression for storage or transmission; (ii) enhancement or restoration; (iii) analysis, recognition, and understanding; or (iv)(More)
