This method firstly extracts multiple features of target in theses sub-band images after transforming the IR images using discrete wavelet frame transform.

According to the discrete wavelet frame transform coefficients, the clarity measure of each pixel in each multifocus image was calculated.

This paper describes a discrete wavelet frame transform based multifocus image fusion algorithm.

Small target detection based on discrete wavelet frame transform and fusion scheme

Aim at the characteristic that redundancy and shift-invariance of wavelet frame can reserve detail information of image preferably,the approach that combine discrete wavelet frame of with the cross band pixel selection was proposed and applied to integrate infrared and visible images.
