We present a novel multi-view video acquisition system using object tracking-based multi-PTZ camera control. Proposed system captures multi-view videos for an object-of-interest by controlling multi-PTZ cameras to focus on it. Control information of each PTZ camera is calculated by homography and a tracked position of the object-of-interest in a top-view image. Moreover, object tracking is performed...
Streaming Feed has become one of the most used utility now-a-days. Starting from Home-Security to Business Surveillance, streaming feed is utilized everywhere. However, due to unstable network bandwidth, frequent buffering and delay occurrence usually creates degraded user experience. One of the ways to avoid this is to use Adaptive Bit rate Streaming. Among various protocols supporting this Adaptive...
This paper investigates the wireless mesh IP video surveillance models and evaluates their performance in terms of throughput, End-to-End delay and jitter. Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN...
This paper considers the joint effect of simultaneous transmission methods and user interfaces on QoE of Multi-View Video and audio (MVV-A) over IP networks. When the user wants to change his/her viewpoint, if the user's terminal already receives the video stream requested, the viewpoint change can be done quickly. Otherwise, it needs to request the video to the server. As the MVV transmission schemes...
In this paper, we propose a fuzzy feature-based method for online body tracking using an IP PTZ camera. Because the camera uses a built-in Web server, camera control entails response time and network delays, and thus, the frame rate is irregular and generally low (3-7 fps). Our method has been designed specifically to perform in such conditions. It detects in every frame, candidate targets by extracting...
This paper investigates QoE (quality of experience) of MVV (multi-view video) and audio transmission over IP networks. Unlike previous works that mainly discuss MVV transmission from aspects of video codecs, we study MVV and audio transmission under various IP traffic and delay conditions by experiment. We compare two schemes: a scheme that the user watches a single viewpoint, and the one that he/she...
