JPEG Image Retrieval Based on A/D Energy Histograms
Xingming Sun · Jisuanji gongcheng · 2004
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.
