Fast Multi-Resolution Image Querying Using Color Characteristics
Introduction
Content-based image retrieval (CBIR), also known as query by image content (QBIC) and content-based visual information retrieval (CBVIR) is the application of computer vision to the image retrieval problem, that is, the problem of searching for digital images in large databases.
Content-based means that the search will analyze the actual contents of the image. The term 'content' in this context might refer colors, shapes, textures, or ....etc

Abstract
In this paper, we propose a method of image resolution enhancement using a single image. The proposed method enhances the resolution by emphasizing the high frequency of a magnified low resolution image. Experimental results show that the performance of our method has been improved by 13%-25% over the conventional interpolation methods.

Abstract
Digital watermarking technique emerged as a tool for protecting the multimedia data from copyright infringement. In digital watermarking an imperceptible signal is embedded into the host image, which uniquely identifies the ownership. In the proposed algorithms, DNA sequence is used as a digital watermark, as the DNA sequences are unique and difficult to copy. This paper proposes two algorithms namely content based watermark algorithm using DNA sequence (CBDNA) and user specified watermark algorithm using D ....etc

1. Introduction
There is always a demand for higher quality and higher resolution images. The level of image detail is crucial for the performance of many computer vision algorithms. Current imaging devices typically consist of arrays of light detectors. A detector determines pixel intensity values depending upon the amount of light detected from its assigned area in the scene. The spatial resolution of images produced is proportional to ....etc

Fuzzy Random Impulse Noise Removal
From Color Image Sequences



Abstract

In this paper, a new fuzzy filter for the removal of
random impulse noise in color video is presented. By working with
different successive filtering steps, a very good tradeoff between
detail preservation and noise removal is obtained. One strong filtering
step that should remove all noise at once would inevitably
also remove a considerable amount of detail. Therefore, the noise
is filtered step by step. In each step, noisy pixe ....etc

Discrete Wavelet Transform-Based Satellite Image Resolution Enhancement




INTRODUCTION

RESOLUTION of an image has been always an important
issue in many image- and video-processing applications,
such as video resolution enhancement , feature extraction
, and satellite image resolution enhancement .
Interpolation in image processing is a method to increase
the number of pixels in a digital image. Interpolation has been
widely used in many image ....etc
