Analysis of Non- Subsampled Contourlet Transform for Medical Image Fusion

Evergreen
In this paper, at different picture representation levels, such as the feature, pixel, decision-making, and data levels, images are presented. Pixels in pixel-level image fusion uniquely identifies a group of pixels in several source images, and the fused image may then be produced.

Brain medical image fusion scheme based on shuffled frog‐leaping algorithm and adaptive pulse‐coupled neural network

IET Image Processing, 2021
Aiming at the problems of low contrast and blurred edge textures in medical image fusion, a new fusion scheme in non‐subsampled contourlet transform (NSCT) domain is proposed to improve the quality of fused brain images which is based on pulse‐coupled ...

Hybrid image denoising method based on non‐subsampled contourlet transform and bandelet transform

IET Image Processing, 2018
The second generation bandelet transform uses the two‐dimensional (2D) separable wavelet transform to improve its image denoising and compression performance. However, the 2D separable wavelet transform is not a shift‐invariant transform and therefore cannot capture geometric information well.

Image Fusion Method based on Non-Subsampled Contourlet Transform

Journal of Software, 2012
Considering human visual system and characteristics of images, a novel image fusion strategy is presented for panchromatic high resolution image and multispectral image in non-subsampled contourlet transform (NSCT) domain. The NSCT can give an asymptotic optimal representation of edges and contours in image by virtue of its characteristics of good ...

Gradient‐Aware Multiscale Feature Enhancement With Reliability Attention for Multi‐Focus Image Fusion

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose MSFE‐Net, an algorithm for multi‐focus image fusion that combines gradient‐aware multi‐scale feature enhancement, focus‐reliability attention based on local‐variance statistics, and an enhanced spatial frequency fusion strategy using four‐directional gradients with local context and morphological refinement to produce robust decision maps ...
