Effective Fuzzy Clustering Algorithm for Abnormal MR Brain Image Segmentation
In image segmentation, one challenge is how to deal with the nonlinearity of real data distribution, which often makes segmentation…
Reversible Data Hiding Based on Histogram Modification of Pixel Differences
Abstract : In this Project, we present a reversible data hiding scheme based on histogram modification. We exploit a binary…
A Unified Relevance Feedback Framework for Web Image Retrieval
Abstract : Although relevance feedback (RF) has been extensively studied in the content-based image retrieval community, no commercial Web image…
Comparison and improvement of wavelet-based image fusion
Abstract Wavelet-based image fusion techniques can generally be classified into three main categories: orthogonal, biorthogonal, and non-orthogonal wavelets. Although these…
An Automatic Wavelet Based- Nonlinear Image Enhancement Technique for Aerial Imagery
Abstract Recently, a wavelet-based dynamic range compression technique has been introduced to improve the visual quality of digital images captured…
