Saliency Detection has emerged as a hot topic due to its potential application in image and video understanding. Most existing saliency detection algorithms focus on two-dimensional information while the depth information is often ignored. In this paper, we first create the salient object ground truth of a specific image dataset which contains 600 RGB-D(More)
As the explosive growth of the web image data, image tag ranking used for image retrieval accurately from mass images is becoming an active research topic. However, the existing ranking approaches are not very ideal, which remains to be improved. This paper proposed a new image tag saliency ranking algorithm based on sparse representation. we firstly(More)
