Abstract

The invention provides an image fusion method and an image fusion device based on an un-decimated morphological wavelet. The image fusion method and the image fusion device based on the un-decimated morphological wavelet are applicable to the field of image processing. The image fusion method comprises the steps of decomposition, fusion and reconfiguration. The image fusion method based on the un-decimated morphological wavelet has the advantages that a block effect is avoided.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to an image fusion method and device based on non-decimation morphological wavelet. Background technique [0002] Since Heijmans and Goutsias proposed the concept of Morphological Wavelets (Morphological Wavelets) in 2000, and successfully unified most linear wavelets and nonlinear wavelets to form a unified framework for multi-resolution analysis, various wavelet-based image fusion method. [0003] Compared with the traditional wavelet transform, the morphological wavelet transform has some very useful properties, such as fast operation, integer transformation, and more effective representation of edge information. However, for the application of image fusion, there are not many research results at present, and they are limited to multi-focus image fusion. [0004] The image fusion method based on morphological wavelet provided by the prior art has three steps, which are respectiv...
