基于MATLAB GUI的刑事图像小波域融合

Forensic Image Fusion in Wavelet Domain Based on MATLAB GUI

图像融合在刑事图像处理中有着广泛的应用。由于常用软件提供的图像融合方法往往比较单一,适用条件有限,本文借助MATLAB GUI平台对图像融合算法设计程序以解决上述问题。以小波分析方法为例,使用新型的形态小波变换构造图像融合算法,并使用MATLAB GUI设计刑事图像融合界面,实现人机交互。计算机仿真结果表明,对于典型的刑事图像,形态小波融合方法在信息熵等评价指标方面都显现出优势,与Photoshop软件处理后的效果相比,细节更加清晰,而基于MATLAB GUI开发的刑事图像融合界面操作简单,融合性能更直观。由于MATLAB GUI平台的开放性,本文的研究易于转化为实际应用,并可不断进行功能扩展,有利于综合性的刑事图像融合处理软件的开发。

Image fusion has been widely used in forensic image processing. Since the fusion method provided by the common used software is often simple, adapting to some limited conditions, this paper proposed a program design of the image fusion algorithm based on MATLAB GUI platform to solve the above problems. As an example of wavelet analysis method, the new morphological wavelet transform was used to construct the image fusion algorithm and the MATLAB GUI to design the interface of the forensic image fusion so that the human-computer interaction could be realized. Computer simulation results showed that, for a typical forensic image, the morphological wavelet fusion method has advantages in both the information entropy and other evaluation indicators. Compared with the effect produced by Photoshop, the newly established method hereof is clearer in the details, making the forensic image fusion interface developed on the base of MATLAB GUI simpler to operate and the fusion performance more intuitive. Because of the openness of MATLAB GUI platform, the research of this paper is easy to transform into practical application, and its functions can be expanded continuously, beneficial for developing comprehensive forensic image fusion processing software.
