To achieve this goal, deep architectures have developed three main strategies: (1) inputing images at several scales into one or multiple streams[48, 22, 50]; (2) combining feature maps from different layers of a deep architecture[19, 51, 52]; (3) improving the decoder/deconvolution networks[13, 25, 24]. HED performs image-to-image prediction by means of a deep learning model that leverages fully convolutional neural networks and deeply-supervised nets, and automatically learns rich hierarchical representations that are important in order to resolve the challenging ambiguity in edge and object boundary detection. Thus the improvements on contour detection will immediately boost the performance of object proposals. 5, we trained the dataset with two strategies: (1) assigning a pixel a positive label if only if its labeled as positive by at least three annotators, otherwise this pixel was labeled as negative; (2) treating all annotated contour labels as positives.
