The invention discloses a complete saliency object detection method using contour detection. The method comprises the steps of segmenting an image by use of a super-pixel segmentation method, and constructing the segmented images into a graphical mode; acquiring a saliency map based on contour extraction; acquiring a binary segmentation map based on a background template; and obtaining a final saliency map based on the saliency map and the binary segmentation map. According to the complete saliency object detection method using contour detection, not only can salient regions of the image be further highlighted, but also a background region is excellently inhibited, and the method can be applied to scenes such as image retrieval, image segmentation, image classification, target identification and so on.
