Regarding the security of ATM systems situated at various locations throughout world, constant monitoring via surveillance machine is required. Even though ATMs are equipped with manual protection, several theft events have made headlines over past few decades. Since continuous provides an alternative to security, it not feasible for banks do so every one these ATMs. With much data generated by...

Video compression has become increasingly crucial as video resolution and bitrate have surged in recent years. However, most widely applied methods do not fully exploit the characteristics of Human Visual System (HVS) to reduce perceptual redundancy videos. In this paper, we propose a novel method that integrates visual saliency information with foveation redundancy. We present new approach sub...

Compression methods based on inpainting are an evolving alternative to classical transform-based codecs for still images. Attempts apply these ideas video compression rare, since reaching real-time performance is very challenging. Therefore, current approaches focus simplified frame-by-frame reconstructions that ignore temporal redundancies. As a remedy, we propose highly efficient, capable pre...

In this paper a novel connectionist approach for video compression is presented. The basic idea is to extend to the temporal dimension the architecture used for the compression of still images. A multilayer perceptron (MLP) with in nite impulse response (IIR) synapses, embedded in a new quad-tree framework for video segmentation, is employed to take into account the video temporal dynamics. In ...

Diierent coding/decoding schemes for video frames require diierent amount of CPU processing overheads, and result in diierent amount of frame data compression. In this paper, we study the performance of alternative codec schemes as supported in a video conferencing software called NV. We present the concept of momentum which is the number of blocks in video frame whose contents have been change...

In this presentation, a broad overview of video communication networks is provided. Numerous video communication applications are currently being developed including digital television, video streaming, video-on-demand, and video conferencing. Efficient storage and communication requires video data to be represented in compressed form. Various video compression standards have been developed by ...

The recent explosion in digital video storage and delivery has presented strong motivation for high performance video compression solutions. An efficient video compression technique must preserve the trade-off between compression ratio and the quality of the video. The performance of existing image and video coding standards generally degrade at low bit-rates because of the underlying block bas...

The characteristics of “non natural” images, such as predictive error frames used in video compression, present a challenge for traditional compression techniques. Particularly difficult are small images, such as QCIF, where compression artifacts at low data rates are more noticeable. In this paper, we investigate techniques to improve the performance of a wavelet-based, rate scalable video cod...
