A novel algorithm for extracting the regions of interest (ROI) from face images is presented in this paper. The novelty of the algorithm comes from its <i>multi-resolution cellular analysis</i> coupled with an adaptive thresholding technique incorporating a unique idea of <i>exponential averaging</i>. The complexity of the cellular ROIs reported by the(More)
This paper presents efficient methods of vertical handoffs from UMTS to WLAN and vice versa in a loose coupling architecture. When a mobile terminal (MT) moves from UMTS to WLAN, it performs mobile IP (MIP) registration with home agent (HA). Subsequently, HA needs to perform location update signaling with UMTS network to make the MT reachable from UMTS. If(More)
