Video up-conversion takes significant place in various application areas. One of important application areas is standard-definition television (SDTV) video processing to get high-definition television content (HDTV) for broadcast. However, high-quality upconversion is a challenging task. Most practical implementations use spatial domain processing such as video frame interpolation for video up-...

In this busy world, gestures play an vital role in humans daily life in order to convey data and motions of human being. So gesture Recognition is a part of the Human computer Interaction (HCI). In recent years Human Computer Interaction has become an attractive field. Hardware devices like mouse, keyboard, joystick can be replaced by compatible touch less technologies. Different proposed model...

The project focuses on the system-level modeling of image and video processing systems. Based on the models given, image and video compression and decompression standards ex. H.263, MPEG-4 will be implemented in a formal, consistent and extensible framework such a s i n Ptolemy with well-deened and optimized processing primitives. The models of computation and an implementation of image and vid...

Smart cameras combine video sensing, video processing and communication onto a single embedded device. Due to their high onboard processing and communication power they are able to perform sophisticated video tasks in real time and can, therefore, react to changes in the camera’s environment. Such embedded smart cameras are excellent candidates for reactive sensor systems. In this paper we desc...

A'transputer-based multiprocessor system for visual communication applications is presented. H.261, the encoding/decoding standard for video telephones recommended by CCITT, is implemented in this system for demonstration. Fundamental video processing operators, such as 3 x 3 discrete Laplacian, are also implemented. Up to 20.4 frames per second (fps) video replaying rate and about 7.2 fps proc...

Mobile computers typically have limited energy for computing and communications due to short battery lifetimes. Encoding, decoding, and transmission of video information require significant computing and communication resources. Low power encoding and decoding schemes have received much attention. In this paper, we focus on processing encoded video for transmission under low battery power condi...

We present 3D video fragments, a dynamic point sample framework for real-time 3D video. By generalizing 2D video pixels towards 3D irregular point samples we combine the simplicity of conventional 2D video processing with the power of more complex polygonal representations for 3D video. We propose a differential update scheme exploiting the spatio-temporal coherence of the video streams of mult...

The ability to manipulate the temporal dependencies in coded video data is important for a number of compressed-domain video processing tasks. This paper formulates the general problem and examines it in the context of MPEG. This is used to develop a method for performing frame conversions in MPEG coded video data. These frame conversions are used to develop compressed-domain video processing a...
