Notably, the bicycle class has the worst AR and we guess it is likely because of its incomplete annotations. Edge boxes: Locating object proposals from edge. [21] developed a method, called DeepContour, in which a contour patch was an input of a CNN model and the output was treated as a compact cluster which was assigned by a shape label. Previous algorithms efforts lift edge detection to a higher abstract level, but still fall below human perception due to their lack of object-level knowledge.

Object contour detection with a fully convolutional encoder-decoder network. For example, the standard benchmarks, Berkeley segmentation (BSDS500)[36] and NYU depth v2 (NYUDv2)[44] datasets only include 200 and 381 training images, respectively. Moreover, we will try to apply our method for some applications, such as generating proposals and instance segmentation. As the contour and non-contour pixels are extremely imbalanced in each minibatch, the penalty for being contour is set to be 10 times the penalty for being non-contour. which is guided by Deeply-Supervision Net providing the integrated direct Different from previous low-level edge A new way to generate object proposals is proposed, introducing an approach based on a discriminative convolutional network that obtains substantially higher object recall using fewer proposals and is able to generalize to unseen categories it has not seen during training.
