To achieve multi-scale and multi-level learning, they first applied the Canny detector to generate candidate contour points, and then extracted patches around each point at four different scales and respectively performed them through the five networks to produce the final prediction. It is apparently a very challenging ill-posed problem due to the partial observability while projecting 3D scenes onto 2D image planes. It is likely because those novel classes, although seen in our training set (PASCAL VOC), are actually annotated as background. Different from DeconvNet, the encoder-decoder network of CEDN emphasizes its asymmetric structure. Therefore, the traditional cross-entropy loss function is redesigned as follows: where refers to a class-balancing weight, and I(k) and G(k) denote the values of the k-th pixel in I and G, respectively.

Being fully convolutional, the developed TD-CEDN can operate on an arbitrary image size and the encoder-decoder network emphasizes its symmetric structure which is similar to the SegNet[25] and DeconvNet[24] but not the same, as shown in Fig. However, since it is very challenging to collect high-quality contour annotations, the available datasets for training contour detectors are actually very limited and in small scale. The final prediction also produces a loss term Lpred, which is similar to Eq. (up to the fc6 layer) and to achieve dense prediction of image size our decoder is constructed by alternating unpooling and convolution layers where unpooling layers re-use the switches from max-pooling layers of encoder to upscale the feature maps. refined approach in the networks. A ResNet-based multi-path refinement CNN is used for object contour detection. Moreover, we will try to apply our method for some applications, such as generating proposals and instance segmentation.

Skip connections between encoder and decoder are used to fuse low-level and high-level feature information. CEDN fails to detect the objects labeled as background in the PASCAL VOC training set, such as food and applicance. This is why many large scale segmentation datasets[42, 14, 31] provide contour annotations with polygons as they are less expensive to collect at scale. Summary. This allows our model to be easily integrated with other decoders such as bounding box regression[17] and semantic segmentation[38] for joint training.

DUCF_{out}(h,w,c)(h, w, d^2L), L We also note that there is still a big performance gap between our current method (F=0.57) and the upper bound (F=0.74), which requires further research for improvement. We also integrated it into an object detection and semantic segmentation multi-task model using an asynchronous back-propagation algorithm. Early research focused on designing simple filters to detect pixels with highest gradients in their local neighborhood, e.g. By combining with the multiscale combinatorial grouping algorithm, our method can generate high-quality segmented object proposals, which significantly advance the state-of-the-art on PASCAL VOC (improving average recall from 0.62 to 0.67) with a relatively small amount of candidates (~1660 per image).

AndreKelm/RefineContourNet 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]. A quantitative comparison of our method to the two state-of-the-art contour detection methods is presented in SectionIV followed by the conclusion drawn in SectionV. Semantic pixel-wise prediction is an active research task, which is fueled by the open datasets[14, 16, 15]. Due to the asymmetric nature of image labeling problems (image input and mask output), we break the symmetric structure of deconvolutional networks and introduce a light-weighted decoder.
