SAR图像特征数据立方体的构造

图像数据立方体的建立有助于图像数据的基于视觉内容的分析和多种知识的挖掘,包括汇总、分类、比较、关联和聚类.图像数据立方体对于图像分析是很有用的模型.实现一个维数很大的数据立方体是很困难的.但如果维数不够,则会使图像的建模范围过于粗糙、受到限制和不精确的扩展.因此,如何设计出既能满足效率要求,又能有足够的表达能力的图像数据立方体,是个亟待研究的问题.文中借鉴前人的思路和方法,构造了SAR图像立方体的模型.

Construction of Feature Data Cubes of SAR Image

The construction of an image data cube will facilitate both the multiple dimensional analysis of image based primarily on visual contents and the exploration of multiple kinds of knowledge, including summarization, classification, comparison, association, and clustering. The image cube is a useful model for image analysis. It is difficult to implement efficiently a data cube with a large number of dimensions, but insufficient number of dimensions may lead to a rough, limited, and imprecise modeling scale of an image. The problem of how to design a multimedia data cube that may strike a balance between efficiency and the power of representation, therefore, needs a prompt solution. By using for reference earlier ideas and methods this paper constructs the model of SAR image data cubes.
