摘要

针对红外图像在亮度分布、对比度以及细节清晰度上的不足，提出一种基于双树复小波与多尺度特征的红外图像融合增强方法。其中，利用自然对数的斜率递减的特点，提出一种自适应的对数斜率变换函数，分别对每一像素进行变换拉伸，优化场景的亮度分布和对比度；在对数斜率变换的基础上，提出一种基于自适应系数的非锐化掩蔽方法，提升图像的边缘和细节的清晰度；借助双树复小波变换的多尺度与多方向特性，分别将两增强图像分解为多尺度、多方向的子带，然后根据自定义的亮度权重图与细节权重图，对相同尺度、相同方向的子带进行加权融合，最后对融合的子带进行双树复小波反变换，获得效果理想的红外图像。从视觉感知和量化数据两方面对提出方法进行性能评估，结果显示提出方法比现有方法具有更好的视觉质量和更高的平均梯度、空间频率和信息熵，因此提出方法能够更好地应用于红外成像领域。

Abstract

Aiming at the shortcomings of infrared images in terms of brightness distribution

contrast

and detail clarity

an infrared image fusion enhancement method based on dual tree complex wavelet and multi-scale features is proposed. Therein

by utilizing the decreasing slope of natural logarithm

an adaptive logarithmic slope transformation function is proposed to enhance the brightness distribution and contrast of the scene by transforming and stretching each pixel separately. On the basis of logarithmic slope transformation

a non-sharpening masking method based on adaptive coefficients is proposed to enhance the clarity of image edges and details. By utilizing the multi-scale and multi-directional properties of the dual tree complex wavelet transform

the two enhanced images are decomposed into multi-scale and multi-directional sub-bands

respectively

and according to the custom brightness weight map and detail weight map

the sub-bands of the same scale and direction are weighted and fused. Finally

the fused sub-bands are subjected to dual tree complex wavelet inverse transform to obtain the ideal infrared image. The performance evaluation of the proposed method was conducted from both visual perception and quantitative data perspectives

and the results showed that the proposed method has better visual quality and higher average gradient

spatial frequency and information entropy than existing methods. Therefore

the proposed method would be a better method in the field of infrared imaging.
