1Salient Object Detection: A Survey

Abstract—Detecting and segmenting salient objects in natural scenes, also known as salient object detection, has attracted a lot of focused research in computer vision and has resulted in many applications. However, while many such models exist, a deep understanding of achievements and issues is lacking. We aim to provide a comprehensive review of the recent progress in this field. We situate salient object detection among other closely related areas such as generic scene segmentation, object proposal generation, and saliency for fixation prediction. Covering 256 publications we survey i) roots, key concepts, and tasks, ii) core techniques and main modeling trends, and iii) datasets and evaluation metrics in…
