Recurrent Attentional Networks for Saliency Detection
Convolutional deconvolution networks can be adopted to perform end to end saliency detection. But, they do not work well with objects of multiple scales. To overcome such a limitation, in this work, we propose a recurrent attentional convolutional deconvolution network (RACDNN) Using spatial transformer and recurrent network units, RACDNN is able to iteratively attend to selected image sub regions to perform saliency refinement progressively. Besides tackling the scale problem, RACDNN can also learn context aware features from past iterations to enhance saliency refinement in future iterations. Experiments on several challenging saliency detection datasets validate the effectiveness of RACDNN, and show that RACDNN outperforms state of the art saliency detection methods.
