摘要： 提出了一种新的基于DCT系数的A/D能量直方图的图像检索方法,其特点是直接在DCT域中统计图像的A/D能量直方图,不需要解压缩,大大降低了计算复杂度,同时对图像的平移、旋转和尺度变换有较好的鲁棒性。试验结果表明这种图像检索方法具有良好的检索性能。

Abstract: This paper presents a novel JPEG image retrieval method based on A/D energy histograms of DCT coefficients . The method directly computes the A/D energy histograms from DCT domain without decompressing the image so that it saves a lot of computation cost At the same time, it is robust to the translation, rotation and scale transform with minor disturbance. Experimental results demonstrate the method has a good performance both in retrieval efficiency and effectiveness.
