چکیده

Due to the strong correlation between symmetric frames, video signals have a high degree of temporal redundancy. Motion estimation techniques are computationally expensive and time-consuming processes used in compression reduce The block-matching technique is, on other hand, most popular efficient different motion compensation techniques. based generally uses minimization either mean square error (MSE) or absolute difference (MAD) order find appropriate vector. This paper proposes remove highly temporally redundant information contained each block signal using removing redundancy (RTR) improve data rate efficiency signal. A comparison PSNR values this those JPEG standard is made. As result its moderate memory computation requirements, algorithm was found be suitable for mobile networks embedded devices. Based detailed set testing scenarios obtained results, it evident that RTR allowed ratio 22.71 95% loss bit reduction while maintaining sufficient intact quality with minimized loss.

Using Redundancy to Repair Video Damaged by Network Data Loss

With rapid progress in both computers and networks, real-time multimedia applications are now possible on the Internet. Since the Internet was designed to support traditional applications, multimedia applications on the Internet often suffer from unacceptable delay, jitter and data loss. Among these, data loss often has the largest impact on quality. In this paper, we propose a new forward erro...

Nonlinear Network Time-Series Forecasting Using Redundancy Reduction

In this paper we propose an efficient method for forecasting highly redundant time-series based on historical information. First, redundant inputs and desired outputs are compressed and used to train a single network. Second, network output vectors are uncompressed. Our approach is successfully tested on the hourly temperature forecasting problem.

Groundwater Monitoring Network Optimization with Redundancy Reduction

Three optimization models are proposed to select the best subset of stations from a large groundwater monitoring network: ~1! one that maximizes spatial accuracy; ~2! one that minimizes temporal redundancy; and ~3! a model that both maximizes spatial accuracy and minimizes temporal redundancy. The proposed optimization models are solved with simulated annealing, along with an algorithm parametr...

Lossless Medical Image Compression using Redundancy Analysis

We studied two image characteristics, the smoothness and the similarity, which give rise to local and global redundancy in image representation. The smoothness means that the gray level values within a given block vary gradually rather than abruptly. The similarity means that any patterns in an image repeat itself anywhere in the rest of the image. In this sense, we proposed a lossless medical ...

Video Compression Using Matching

|The use of matching pursuit (MP) to code video using over-complete Gabor basis functions has recently been introduced 8]. In this paper, we propose new functionalities such as SNR scalability and arbitrary shape coding for video coding based on matching pursuit. We improve the performance of the baseline algorithm in 8] by proposing a new search and a new position coding technique. The resulti...
