| 摘 要： | 基于内容的检索是近年来的研究热点之一,现在已有许多基于象素域的图像检索技术,目前数据压缩也已成为多媒体应用的标准模式,静态图像压缩主要采用JPEG技术,研究基于传统JPEG和JPEG2000的图像检索方法成为必然。本文综述近年来出现的基于JPEG核心算法离散余弦变换和JPEG2000核心算法离散小波变换的图像检索技术。

| Abstract: | Content-based image retrieval techniques are the research focuses at the end of early years. At present, a number of indexing techniques that operate in the pixel domain have been reported. It is becoming criterion that multimedia data are stored and transformed in the compressed format.Still image compression normally uses JPEG techniques,so it needs to study indexing techniques based on tradition JPEG and JPEG2000.In this paper, we present a review of static image indexing in the Discrete Cosine Transform Domain that is JPEG core arithmetic and Discrete Wavelet Transform Domain that is JPEG2000 core arithmetic. |
