Title:
Saliency Detection in Images and Videos: From Visual Perception to Deep Learning

Speaker:
Prof Jinchang Ren, Professor of Computing Sciences
Robert Gordon University, Aberdeen, U.K.

Visual attention is a kind of fundamental cognitive capability that allows human beings to focus on the region of interests (ROIs), i.e. the saliency parts, under complex natural environments. Saliency detection plays an important role in a wide range of computer vision tasks, especially for salient object detection. In this talk, conventional models for saliency detection is covered first, based on visual perception and gestalt laws in unsupervised saliency detection from images, where both bottom-up and top-down attention mechanisms are integrated for more effective detection.

Following the success in conventional models, we proposed deep learning - based saliency detection in videos. By taking several consecutive frames as input, both the spatial and temporal characteristics are considered when computing saliency maps through fusion of hybrid high-level features. In addition, applications of saliency detection in some interesting applications are also demonstrated.
