A Study of Transform Domain based Image Enhancement Techniques

An alteration of the low complexity upgrades strategies that are in light of the singular value decomposition (SVD) for saving the mean brightness of a given picture. In spite of the fact that the SVD structured systems upgrade the reduced complexity pictures by scaling its particular worth grid, they may neglect to deliver palatable results for some low difference pictures. The weighted total ...

Image Enhancement Using Transform Domain Based Image Fusion Technique

Image enhancement for the better quality of image is required in various image based application. One of the technique to enhance the image is image fusion. It is an effective way for optimum utilization of large volumes of images from multiple sources. It extracts complete information from source images into the result, without introducing any artifacts or inconsistencies. In this process, it ...

A Robust Image Denoising Technique in the Contourlet Transform Domain

The contourlet transform has the benefit of efficiently capturing the oriented geometrical structures of images. In this paper, by incorporating the ideas of Stein’s Unbiased Risk Estimator (SURE) approach in Nonsubsampled Contourlet Transform (NSCT) domain, a new image denoising technique is devised. We utilize the characteristics of NSCT coefficients in high and low subbands and apply SURE sh...

A New Method for Speech Enhancement Based on Incoherent Model Learning in Wavelet Transform Domain

Quality of speech signal significantly reduces in the presence of environmental noise signals and leads to the imperfect performance of hearing aid devices, automatic speech recognition systems, and mobile phones. In this paper, the single channel speech enhancement of the corrupted signals by the additive noise signals is considered. A dictionary-based algorithm is proposed to train the speech...

A Study and Evaluation of Transform Domain based Image Fusion Techniques for Visual Sensor Networks

This paper presents an evaluation of different image fusion techniques. There are many image fusion techniques which have been developed in a number of applications. Image fusion incorporates the data from several images of one scene to obtain an enlightening image which is more appropriate for human visual perception or additional vision processing. Image quality is closely connected to image ...
