Translated Title

DCT block feature based saliency detection in JPEG image with background prior

Translated 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.
