Higher Order Partial Differential Equation Based Method for Image Enhancement
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 6
Abstract
Many color image enhancing techniques have been proposed to eliminate noise and uninteresting details from an image, without blurring semantically important structures such as edges. PDEbased methods have been proposed to tackle the problem of image denoising with a good preservation of edges and also to explicitly account for intrinsic geometry. The existing method can be viewed as generalization of the Bettahar – Stambouli filter to multivalued images. The proposed algorithm is based on using single vectors of gradient magnitude and the fourth order derivatives as a manner to relate different color components of the image. The Partial Differential Equation based algorithm is more efficient than existing models and some previous works at color images denoising and sharpens the edges efficiently without creating false colors.
