摘要

图像特征谱给予图像原始特征以富有表达力的、统一的、可操作的形式化描述。本文针对单一图像特征谱在应用时对图像信息表达的片面性和干扰性问题，提出了一种自适应特征谱，该特征谱利用纹理谱对纹理特征的描述将图像区域划分为光滑区和纹理区，对于光滑区域将选择颜色谱作为区域特征，而对于纹理区将选择纹理谱作为特征值，因此它可以对具有不同视觉特点的图像给予灵活的特征描述。为了检验该特征谱的有效性，我们将它应用于基于内容的图像检索中，实验结果表明，利用所提出的自适应特征谱具有很好的检索效果和较小的时间复杂度。

Abstract

Feature spectrum descriptors give the rich

unified

workable expressions of the original characteristics of an image. In this paper

to solve the unilateral and interference problems in the application of one single feature spectrum descriptor

adaptive feature spectrum descriptor is proposed. Suitable features are choosen according to the characteristics of the image region itself. In order to test the performance of the feature spectrum descriptor

it was appllied to the content-based image retrieval. Experiments show that the new feature spectrum descriptor has good retrieval efficiency

and small time complexity.
