Active applications can add value to communication. Yet it involves sophisticated domain knowledge and complex development process. In this paper we discuss a framework for the construction of complex active network applications. Its design motivation is to enable an expert to develop complex active applications as a value added communication service and make it available for repeated use by th...

This paper presents the Customisable Modular Platform (CMP) approach. The aim is to accelerate FPGA application development by raising the level of abstraction and facilitating design reuse. The solution is based on network of Nodes, communicating using packetbased protocol. The approach is illustrated using SoftSONIC, a CMP for video applications. Our approach promotes modularity and design re...

Efficient video content analysis is an unsolved problem, especially for real-life surveillance videos due to their low resolution and illustration variations. A novel framework to efficiently and robustly convert a surveillance video clip into one abstraction image containing the integrated contour of interested objects is proposed. It has the following novelties: 1) an improved w-SIFT algorith...

We present results on an extension to our approach for automatic sports video annotation. Sports video is augmented with accelerometer data from wrist bands worn by umpires in the game. We solve the problem of automatic segmentation and robust gesture classification using a hierarchical hidden Markov model in conjunction with a filler model. The hierarchical model allows us to consider gestures...

Video summarization refers to an important set of abstraction techniques aimed to provide a compact representation of the video essential to effectively browse and retrieve video content from multimedia repositories. Most of these video summarization techniques, such as image storyboards, video skims and fast previews, are based on selecting some frames or segments. H.264/AVC has become a widel...

introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...

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...

ion layers. A motivation for a generalized addressing scheme is not at least due to increasing the compatibility between various cores, producing differently arranged output data. Video processing applications typically aim to address data in units of frames, lines, and pixels, defining the desired level of abstraction. Furthermore, multiple clients aim to store results concurrently in a shared...

This research addresses the problem of automatically extracting semantic video scenes from feature films based on multimodal information. A three-stage scene detection scheme is proposed. First, we use pure visual information to extract a coarse-level scene structure based on generated shot sinks. Second, audio cue is integrated to refine the scene detection results by considering various kinds...
