A study of training free salient object detection methods in presence of noise

Salient Object Detection (SOD) has received much attention from the research community due to its increasing applications in the areas such as object detection and recognition, image editing, image and video compression, video summarization and so on. Most of the SOD methods are proposed in literature presuming that the digital images in which salient objects is to be detected, are free from any kind of artifact. SOD in the presence of noise has received much less attention from research community. In this paper, we study and analyze popular salient object detection methods in the presence of Gaussian, Salt and Pepper and Speckle Noises. Extensive experiments are performed on two publicly available SOD datasets viz. MSRA5K and DUT OMRON. The performance of the methods are evaluated in terms of Precision, Recall and F-measure. It is found that Context Aware Saliency Detection (CA) method gives maximum Precision while Graph Based Visual Saliency (GB) gives maximum Recall and F-measure on both the datasets in presence of any of the three noises.
