基于DCT块特征与背景先验的JPEG图像显著性检测算法
DCT block feature based saliency detection in JPEG image with background prior
摘要
Abstract
This paper proposes a novel image saliency detection method dealing with JPEG images,which directly extracts 3 image low-level features (intensity,texture and color) from JPEG DCT blocks and then evaluates image saliency by calculating the shortest path from each internal point to the background.We compare our method with some state-of-the-art methods on the publicly available datasets MSRA-1000.Experimental results show that our method exhibits better performance in terms of four evaluations than some state-of-the-art methods.The final saliency maps indicate that our method can also produce satisfied saliency maps directly in compressed domain.关键词
