An Approach to Color Image enhancement Using Modified Histogram
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 9
Abstract
Image enhancement is one of the key issues in high quality pictures such as digital camera and HDTV. Since Image clarity is very easily affected by lighting, weather, or equipment that has been used to capture the image. These conditions lead to image may suffer from loss of information. In this paper a new technique is introduced to enhance color images with dim regions ,In this technique the lightness component in YIQ color space is transformed then the traditional histogram equalization (HE) method is applied on Y component. The result of modified histogram equalization (MHE) algorithm has been compared with the result of other method like Adaptive Integrated Neighborhood Dependent Approach for Nonlinear Enhancement of Color Images (AINDANE), traditional histogram equalization and Homomorphic Filtering. All algorithms have implemented using Matlab
