Learning to Detect Saliency with Deep Structure
Yu Hu, Zenghai Chen, Zheru Chi, Hong Chuan Fu · 2015
Deep learning has shown great successes in solving various problems of computer vision. To the best of our knowledge, however, little existing work applies deep learning to saliency modeling. In this paper, a new saliency model based on convolutional neural network is proposed. The proposed model is able to produce a saliency map directly from an image's pixels. In the model, multi-level output values are adopted to simulate continuous values in a saliency map. Differing from most neural networks that use a relatively small number of output nodes, the output layer of our model has a large number of nodes. To make the training more efficient, an improved learning algorithm is adopted to train the model. Experimental results show that the proposed model succeeds in generating acceptable saliency maps after proper training.
