摘    要:提出一种基于红外图像分层处理及动态压缩的DDE算法。该算法先将原始14bits红外图像数据信息中的大动态低频背景和小动态高频细节进行分离提取,并分别对提取的细节层和背景层进行相应的灰度增强和灰度抑制处理,再调整和压缩各图层的动态范围并最终合成8bits图像。实验结果表明,该算法能较好地保留并突出原始红外图像中的边缘和细节信息,达到了预期设计的目标。

关 键 词:数字细节增强(DDE)  图像分层处理  动态范围调整  动态压缩

Abstract:In this paper,we put forward a DDE algorithm based on hierarchical processing and dynamic compression of infrared image.At first,this algorithm dissociates the background(with wide dynamic and low frequency) and the detail(with narrow dynamic and high frequency) in the data information(14 bits) of original infrared image,and pick up them respectively.Then,it enhances the gray of details layer and restrains the gray of background layer,and readjusts and compresses dynamic range of each layer.Finally,it composites output image(8 bits).The experimental results show that the proposed algorithm can retain detail information and edges in original infrared image and carry the purpose of design.
Keywords:Digital Details Enhancement  Hierarchical Data Processing  Dynamic Range Adjustment  Dynamic Compression
