An EPLD based low cost transient recorder of video signal bandwidth (sampling rate 25MHz) is presented. It will be used to record and replay video signals. These video signals are handled by a video processing unit, under construction in a VHDL environment. The main advantage of this self made transient recorder is that the video signal processing device, which is under construction in a VHDL e...

The Informedia Digital Video Library contains over 1200 hours of video. Through automatic processing, descriptors are derived for the video to improve library access. A new extension to the video processing is the extraction of geographic references from these descriptors. The operational library interface shows the geographic entities addressed in a given story, highlighting the regions discus...

image processing, digital video processing, image based rendering, computer graphics Here we introduce the concept of a 3D video sprite. We outline an approach for their automatic creation and manipulation. 3D sprites consists of a number of synchronous video streams and mark up information that allows virtual viewpoints with respect to a live action video to be rendered and combined with tradi...

The importance of underwater video surveys as an exploration tool has been steadily increasing over recent years [1]. Better photographic equipment, more effective sources of illumination, and improved processing techniques all make video surveying a reliable tool for seafloor habitat mapping, sediment boundary delineation and groundtruthing, mapping and documentation of forensic and archaeolog...

The advent of affordable wearable devices with a video camera has established the new form of social data, lifelogs, where lives of people are captured to video. Enormous amount of lifelog data and need for on-site processing demand new fast video processing methods. In this work, we experimentally investigate seven hours of lifelogs and point out novel findings: 1) audio cues are exceptionally...

We present the 3D Video Recorder, a system capable of recording, processing, and playing three–dimensional video from multiple points of view. We first record 2D video streams from several synchronized digital video cameras and store pre-processed images to disk. An off-line processing stage converts these images into a time–varying three– dimensional hierarchical point–based data structure and...

W ITH the rapid growth of IPTV and mobile video applications and driven by urgent demands from industry and users, video processing and content sharing technologies have received significant research attention in recent years. Cloud-based video processing and content sharing networks are promising technologies to orchestrate large-scale and efficient video distribution between mobile clients an...

In the world of social media video processing is very popular. A video signal is the term used to describe any sequence of time varying images. This paper presents the architectures for Video Processing algorithm using softcore processor. This hardware/software co-design platform has been implemented on a Xilinx Virtex-5 FPGA (XUPV5-LX110T). Field Programmable Gate Array (FPGA) offers various r...

Power-aware video coding requires a combination of highperformance and flexibility to satisfy perceptual quality requirements and meet low-power constraints. This work explores the use of dynamically configurable algorithms and architectures which leverage two fundamental properties of video processing: 1. Video content and its associated processing are highly nonuniform in both space and time....

We describe the design and implementation of a digital video content management system, iVIEW, for intelligent searching and access of video contents over Internet and wireless devices. The iVIEW system allows full content indexing, searching and retrieval of multilingual text, audio and video material. iVIEW integrates image processing techniques for scenes and scene changes analyses, speech p...
