Interpolation-Free Fractional-Pixel Motion Estimation Algorithms with Efficient Hardware Implementation`

Abstract This paper presents interpolation-free fractional-pixel motion estimation (FME) algorithms and efficient hardware prototype of one of the proposed FME algorithms. The proposed algorithms use a mathematical model to approximate the matching error at fractional-pixel locations instead of using the block matching algorithm to evaluate the actual matching error. Hence,Read More

A Prototyping Virtual Socket System-On-Platform Architecture with a Novel ACQPPS Motion Estimator for H.264 Video Encoding Applications

Abstract H.264 delivers the streaming video in high quality for various applications. The coding tools involved in H.264, however, make its video codec implementation very complicated, raising the need for algorithm optimization, and hardware acceleration. In this paper, a novel adaptive crossed quarter polar pattern search (ACQPPS) algorithm is proposedRead More

Efficient Variable Block Size Selection for AVC Low Bitrate Applications

  ABSTRACT The Advanced Video Coding (AVC) standard proposes the usage of Variable Block Size (VBS) motion-compensated prediction and mode decision aiming for an optimized Rate-Distortion (R-D) performance. Unlike Fixed Block Size (FBS) motion-compensated prediction, where all regions of the pictures are treated similarly in terms of temporal prediction, VBSRead More

Automatic License Plate Recognition (ALPR): A State-of-the-Art Review

Abstract: Automatic license plate recognition (ALPR) is the extraction of vehicle license plate information from an image or a sequence of images. The extracted information can be used with or without a database in many applications, such as electronic payment systems (toll payment, parking fee payment), and freeway and arterialRead More
