Pinheiro, T.-Y. We find that the learned model generalizes well to unseen object classes from the same supercategories on MS COCO and can match state-of-the-art edge detection on BSDS500 with fine-tuning. Each image has 4-8 hand annotated ground truth contours. . Edit social preview. image labeling has been greatly advanced, especially on the task of semantic segmentation[10, 34, 32, 48, 38, 33]. As combining bottom-up edges with object detector output, their method can be extended to object instance contours but might encounter challenges of generalizing to unseen object classes. We further fine-tune our CEDN model on the 200 training images from BSDS500 with a small learning rate (105) for 100 epochs. Statistics (AISTATS), P.Dollar, Z.Tu, and S.Belongie, Supervised learning of edges and object Our method obtains state-of-the-art results on segmented object proposals by integrating with combinatorial grouping[4]. Therefore, its particularly useful for some higher-level tasks. In this section, we introduce our object contour detection method with the proposed fully convolutional encoder-decoder network. Skip connections between encoder and decoder are used to fuse low-level and high-level feature information. Being fully convolutional, our CEDN network can operate on arbitrary image size and the encoder-decoder network emphasizes its asymmetric structure that differs from deconvolutional network[38]. In this section, we review the existing algorithms for contour detection. Monocular extraction of 2.1 D sketch using constrained convex We trained the HED model on PASCAL VOC using the same training data as our model with 30000 iterations.

Summary. 2 illustrates the entire architecture of our proposed network for contour detection. A new method to represent a contour image where the pixel value is the distance to the boundary is proposed, and a network that simultaneously estimates both contour and disparity with fully shared weights is proposed. Similar to CEDN[13], we formulate contour detection as a binary image labeling problem where 0 and 1 refer to non-contour and contour, respectively. Kivinen et al. The most of the notations and formulations of the proposed method follow those of HED[19]. For example, it can be used for image segmentation[41, 3], for object detection[15, 18], and for occlusion and depth reasoning[20, 2]. Measuring the objectness of image windows. synthetically trained fully convolutional network, DeepEdge: A Multi-Scale Bifurcated Deep Network for Top-Down Contour Semantic image segmentation with deep convolutional nets and fully No description, website, or topics provided. Each side-output can produce a loss termed Lside. The thinned contours are obtained by applying a standard non-maximal suppression technique to the probability map of contour. To guide the learning of more transparent features, the DSN strategy is also reserved in the training stage. A fully convolutional encoder-decoder network is proposed to detect the general object contours [10]. Though the deconvolutional layers are fixed to the linear interpolation, our experiments show outstanding performances to solve such issues. Due to the asymmetric nature of A ResNet-based multi-path refinement CNN is used for object contour detection.

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. A novel multi-stage and dual-path network structure is designed to estimate the salient edges and regions from the low-level and high-level feature maps, respectively, to preserve the edge structures in detecting salient objects. Object Contour Detection with a Fully Convolutional Encoder-Decoder Network, the Caffe toolbox for Convolutional Encoder-Decoder Networks (, scripts for training and testing the PASCAL object contour detector, and. 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]. Deepedge: A multi-scale bifurcated deep network for top-down contour Different from previous low-level edge Dive into the research topics of 'Object contour detection with a fully convolutional encoder-decoder network'.

The final high dimensional features of the output of the decoder are fed to a trainable convolutional layer with a kernel size of 1 and an output channel of 1, and then the reduced feature map is applied to a sigmoid layer to generate a soft prediction. All persons copying this information are expected to adhere to the terms and constraints invoked by each author's copyright. 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.

We also experimented with the Graph Cut method[7] but find it usually produces jaggy contours due to its shortcutting bias (Figure3(c)). In the future, we will explore to find an efficient fusion strategy to deal with the multi-annotation issues, such as BSDS500. 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).".
