Only few problems in computer vision have been investigated more vigorously than stereo. Nevertheless, almost all methods use only gray values and most of them are feature-based techniques, i.e., they produce only sparse depth maps. This paper presents an efficient technique for dense stereo correspondence using a new Polychromatic Block Matching. Four different color models (RGB, XYZ, IlI2I 3,...

Lossless image compression has often employed techniques quite separate from those used for text compression or lossy image compression; most standards today employ modelling followed by coding (e.g. the JBIG standard, the IBM Q-coder, CCITT Group 4). Constantinescu and Storer present a lossy image compression scheme that can be viewed as a generalization of lossless dynamic dictionary compress...

Inter prediction is an important component for video coding which exploits the temporal correlation between frames and significantly reduces the redundancy in video sequences. In this paper, we propose a predictive patch matching for inter prediction based on template matching prediction. Besides the surrounding reconstructed pixels which form the template in template matching prediction, our p...

Stereo matching methods are used to estimate disparity values from captured stereo images. They exploit characteristics of binocular disparity for disparity estimation. Stereo images captured under practical conditions have different illumination status, which causes disparity errors in the matching operation. To solve this problem, we can use the adaptive normalized cross correlation (ANCC) as...

The fuzzy file block matching technique (fuzzy matching for short), was first proposed for opportunistic use of Content Addressable Storage. Fuzzy matching aims to increase the hit ratio in the content-addressable storage providers, and thus can improve the performance of underlying distributed file storage systems by potentially saving significant network bandwidth and reducing file transmissi...

This paper proposes a Finger-Knuckle-Print (FKP) recognition algorithm using Band-Limited Phase-Only Correlation (BLPOC)-based local block matching. The phase information obtained from 2D Discrete Fourier Transform (DFT) of images contains important information of image representation. The phase-based image matching, especially BLPOC-based image matching, is successfully applied to image recogn...

In order to describe the main movement of the video a new motion descriptor is proposed in this work. We combine two methods for estimating the motion between frames: block matching and brightness gradient of image. In this work we use a variable size block matching algorithm to extract displacement vectors as a motion information. The cross product between the block matching vector and the gra...

Introduction: The most popular algorithm for the VLSI implementation of motion estimation is the block-based full-search algorithm [1–3]. However, the full-search algorithm notoriously needs high computation load and large memory size. The high computational cost has become a major problem in the implementation of motion estimation. Many papers have proposed different ways to reduce the computa...

Experiment was carried out to study the proprioception accuracy of elderly (61-83 years old) and young (22-36 years old) subjects during contralateral elbow matching in sagittal plane. The subjects performed the task under ordinary condition and under experimental condition (matching forearm attached to the rocking cylindrical platform of low (LS), or high (HS) height, so that the elbow flexion...

There are situations where it is not possible to capture a large document with a given imaging media such as scanner or copying machine in a single stretch because of their inherent limitations. This results in capturing a large document in terms of split components of a document image. Hence, it is necessary is to mosaic the split components into the original and complete document image. In th...
