图像检索技术是多媒体应用中的关键技术，现有的基于内容的图像检索技术大都是基于非压缩域的。

Image retrieval techniques are crucial in multimedia application, a number of retrieval techniques that operate in the pixel domain have been reported in the literature.

该方法在DCT压缩域，通过直接对DCT系数计算，获得图像纹理的统计特征，并作为检索的依据。

The statistical features of the texture images is computed directly from DCT coefficients, and used for image retrieval.
