A fast block-matching algorithm for motion estimation is described for interframe image coding. Utilizing the fact that the motion is searched by a macroblock basis while the compression is performed by a block basis in many video compression standards, the proposed algorithm produces high PSNR and fast computation while keeping the bit-rate as low as those of conventional fast algorithms. The ...

schema matching is a critical step in many applications, such as data warehouse loading, online analytical process (olap), data mining, semantic web [2] and schema integration. this task is defined for finding the semantic correspondences between elements of two schemas. recently, schema matching has found considerable interest in both research and practice. in this paper, we present a new impr...

Combining the features of block matching algorithm and block recursive algorithm a new motion estimation method is proposed for complex motion phenomenon. With the full searching procedure used in block matching algorithm and the adaptive searching procedure used in block recursive algorithm, the proposed combinative algorithm can be used to estimate more complex motion parameters such as trans...

Background: The aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age.Materials and Methods: In this analytical study, twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angel...

A fast block matching algorithm in the feature domain was proposed by Fok and Au which achieves a computation reduction factor of N/2 with search block size of N×N. This paper presents an improved fast block matching algorithm in the integral projections feature domain. This algorithm is based on the fast block matching algorithm in the feature domain and a new motion field sub-sampling scheme....
