Improving visual quality of CT Images through enhancement of base and detail layers
Journal of Applied Science and EngineeringMedical imaging enables doctors to provide faster and more accurate diagnoses of different conditions. Medical images are generally very dark and frequently exhibit degradations such as poor detail or low contrast, which may impact the accuracy and ...

Adaptive curvature-guided image filtering for structure + texture image decomposition
, 2018 A preliminary structure + texture image decomposition is very useful for a number of digital image processing tasks, as different strategies are supposed to be employed for processing the structure and texture image components.

Image resolution enhancement using dual-tree complex wavelet transform [PDF]
, 2010 In this letter, a complex wavelet-domain image resolution enhancement algorithm based on the estimation of wavelet coefficients is proposed. The method uses a forward and inverse dual-tree complex wavelet transform (DT-CWT) to construct a high-resolution

Spectrum decomposition for image/signal coding
, 2013 In conventional subband/wavelet image coding, the subband decomposition is performed on the spatial-domain image. Here, we introduce a novel decomposition where the subband decomposition is performed on the global DCT spectrum of the image.

Image segmentation method using fractal dimension and wavelet decomposition
, 2004 In this paper, a new method using the fractal dimension and wavelet decomposition is proposed to complete the image segmentation between sea and sky in the case of the variety of gray level caused by the reflection of the sunshine on the sea.

An improved infrared image enhancement algorithm based on multi-scale decomposition
, 2014 Due to the restriction of infrared imaging component and the radiation of atmosphere, Infrared images are discontented with image contrast, blurry, large yawp. Aimed on these problems, A multi-scale image enhancement algorithm is proposed.
