Adaptive Pixel Difference Classification, an Efficient and Cost Effective Algorithm for Motion Estimation
نویسندگان
چکیده
In this paper we present a simple adaptive block-matching algorithm for video compression. Our method is an adaptive approach to pixel difference classification (PDC) matching criterion. A constant threshold is used in original PDC algorithm in which optimum threshold varies from sequence to sequence. In contrast to the original PDC algorithm, adaptive PDC (APDC) employs a time variant threshold, where the threshold is obtained from parametric classification of each frame. The proper threshold obtained for each frame is used for subsequent frame. Experimental results indicate that this method can yield further 99% of optimum performance. Key-Words: Block Matching, Motion Estimation, Video Compression.

New adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...
متن کاملAdaptive search area for fast motion estimation
In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...

Robust adaptive estimation of unknown parameter has been an important issue in recent years for reliable operation in the distributed networks. The conventional adaptive estimation algorithms that rely on mean square error (MSE) criterion exhibit good performance in the presence of Gaussian noise, but their performance drastically decreases under impulsive noise. In this paper, we propose a rob...

متن کاملAn Adaptive Hierarchical Method Based on Wavelet and Adaptive Filtering for MRI Denoising
MRI is one of the most powerful techniques to study the internal structure of the body. MRI image quality is affected by various noises. Noises in MRI are usually thermal and mainly due to the motion of charged particles in the coil. Noise in MRI images also cause a limitation in the study of visual images as well as computer analysis of the images. In this paper, first, it is proved that proba...
