Abstract
Saliency detection attracted attention of many researchers and had become a very active area of research. Recently, many saliency detection models have been proposed and achieved excellent performance in various fields. However, most of these models only consider low-level features. This paper proposes a novel saliency detection model using both color and texture features and incorporating higher-level priors. The SLIC superpixel algorithm is applied to form an over-segmentation of the image. Color saliency map and texture saliency map are calculated based on the region contrast method and adaptive weight. Higher-level priors including location prior and color prior are incorporated into the model to achieve a better performance and full resolution saliency map is obtained by using the up-sampling method. Experimental results on three datasets demonstrate that the proposed saliency detection model outperforms the state-of-the-art models.
Highlights
Visual attention is a significant mechanism of the human visual system (HVS)
Inspired by the works of fusing bottom-up and top-down factors [12,13,14], this paper proposes a saliency detection model which fuses bottom-up features with adaptive weight and incorporate higherlevel priors to the model
We evaluate the performance of the texture saliency map, color saliency map, saliency map fusing the texture and color saliency with average weight and adaptive weight respectively and final saliency map on MSRA-1000
Summary
Visual attention is a significant mechanism of the human visual system (HVS). It allows humans to select the most relevant information on visual information from the environment. Visual attention is modeled as saliency detection in computer vision. Saliency detection has drawn a lot of interest in computer vision. It provides fast solutions to several complex processes and has attracted a lot of attention from numerous universities and research institutes. In the past decades many saliency models have been proposed and widely exploited in image segmentation [1,2], object recognition [3,4,5], image retrieval [6], image resizing [7], image/video compression [8,9] and image/ video quality assessment [10,11]
