This paper proposes a novel feature descriptor, named local quantized extrema patterns (LQEP) for content based image retrieval. The standard local quantized patterns (LQP) collect the directional relationship between the center pixel and its surrounding neighbors and the directional local extrema patterns (DLEP) collect the directional information based on(More)
Measurement of visual quality is of fundamental importance to numerous image and video processing applications. This paper introduces an image quality index, visual region of interest weighted quality index (VroiWQI). The index integrates the notion of visual regions of interest with the measurement of structural distortion between the original image and(More)
We present a full reference objective image quality assessment technique which is based on the properties of the human visual system (HVS). It consists of two major components: 1) structural similarity measurement (SSIM) between the reference and distorted images, mimicking the overall functionality of HVS in a top down frame work. 2) A visual attention(More)
Continuous shrinking in feature size, increasing power density etc. increase the vulnerability of microprocessors against soft errors even in terrestrial applications. The register file is one of the essential architectural components where soft errors can be very mischievous, because errors may rapidly spread from there throughout the whole system. Thus,(More)
136 Abstract— In this paper a full reference objective image quality assessment technique is presented which is based on the properties of the human visual system (HVS). By integrating the notion of visual regions of interest with the measurement of structural similarity between the original image and distorted image a Weighted Structural Similarity Index(More)
A mobile ad-hoc network is an infrastructure less self-configuring network of mobile nodes which move their places randomly, move around or join the network. Over the past few years simulation work has been carried out to achieve a new reliable Routing protocol. This paper mainly concentrates on reducing the factors such as End-to- End Delay, Network Load(More)
The local properties of an image can be acquired in many ways. Local Binary Patterns(LBP) operator is one among them in which a centre pixel is referenced with the neighboring pixels to obtain a feature vector. However, the directions are not considered in this method. The Directional Local Extrema Patterns(DLEP) are used to encode the relationship between(More)
In recent years Wireless technology iswidely used with the advent of IEEE 802 standard. Lowrate Wireless personal area networks are widely usedbecause of low cost. A mobile ad-hoc network isinfrastructure less network which consist of mobile devices connected wirelesslyand usually move to other places from time totime, move around or join the network. Over(More)
A new procedure called Color Based Multi-directional Local Motif XoR Patterns (CMDLMXoRP) to index and retrieve image is presented in the paper. Here, joint correlation between directional smart grids is proposed. First, the required directional information is calculated. In the next stage, smart grid XOR patterns are applied to generate transformed(More)
