During training, we fix the encoder parameters (VGG-16) and only optimize decoder parameters. In this section, we introduce our object contour detection method with the proposed fully convolutional encoder-decoder network. Constrained parametric min-cuts for automatic object segmentation. We find that the learned model . Our method not only provides accurate predictions but also presents a clear and tidy perception on visual effect. z-mousavi/ContourGraphCut a fully convolutional encoder-decoder network (CEDN). To address the quality issue of ground truth contour annotations, we develop a dense CRF[26] based method to refine the object segmentation masks from polygons. 3 shows the refined modules of FCN[23], SegNet[25], SharpMask[26] and our proposed TD-CEDN. A fully convolutional encoder-decoder network is proposed to detect the general object contours [10]. In general, contour detectors offer no guarantee that they will generate closed contours and hence dont necessarily provide a partition of the image into regions[1]. . convolutional feature learned by positive-sharing loss for contour In the future, we consider developing large scale semi-supervised learning methods for training the object contour detector on MS COCO with noisy annotations, and applying the generated proposals for object detection and instance segmentation. Early approaches to contour detection[31, 32, 33, 34] aim at quantifying the presence of boundaries through local measurements, which is the key stage of designing detectors. icdar21-mapseg/icdar21-mapseg-eval LabelMe: a database and web-based tool for image annotation. It is tested on Linux (Ubuntu 14.04) with NVIDIA TITAN X GPU. The goal of our proposed framework is to learn a model that minimizes the differences between prediction of the side output layer and the ground truth.

This work was partially supported by the National Natural Science Foundation of China (Project No. To find the high-fidelity contour ground truth for training, we need to align the annotated contours with the true image boundaries. We use the Adam method[5], to optimize the network parameters and find it is more efficient than standard stochastic gradient descent. A more detailed comparison is listed in Table2. Dense Upsampling Convolution. This work builds on recent work that uses convolutional neural networks to classify category-independent region proposals (R-CNN), introducing a novel architecture tailored for SDS, and uses category-specific, top-down figure-ground predictions to refine the bottom-up proposals. potentials. Directly using contour coordinates to describe text regions will make the modeling inadequate and lead to low accuracy of text detection.

It is composed of 200 training, 100 validation and 200 testing images. Bala93/Multi-task-deep-network [19], a number of properties, which are key and likely to play a role in a successful system in such field, are summarized: (1) carefully designed detector and/or learned features[36, 37], (2) multi-scale response fusion[39, 2], (3) engagement of multiple levels of visual perception[11, 12, 49], (4) structural information[18, 10], etc. 13 papers with code HED integrated FCN[23] and DSN[30] to learn meaningful features from multiple level layers in a single trimmed VGG-16 net. In this paper, we scale up the training set of deep learning based contour detection to more than 10k images on PASCAL VOC[14]. The main problem with filter based methods is that they only look at the color or brightness differences between adjacent pixels but cannot tell the texture differences in a larger receptive field. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The detection accuracies are evaluated by four measures: F-measure (F), fixed contour threshold (ODS), per-image best threshold (OIS) and average precision (AP). Summary.

The VOC 2012 release includes 11530 images for 20 classes covering a series of common object categories, such as person, animal, vehicle and indoor. Moreover, to suppress the image-border contours appeared in the results of CEDN, we applied a simple image boundary region extension method to enlarge the input image 10 pixels around the image during the testing stage. Together there are 10582 images for training and 1449 images for validation (the exact 2012 validation set). Given that over 90% of the ground truth is non-contour.

This work brings together methods from DCNNs and probabilistic graphical models for addressing the task of pixel-level classification by combining the responses at the final DCNN layer with a fully connected Conditional Random Field (CRF). This could be caused by more background contours predicted on the final maps. 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. With the further contribution of Hariharan et al. The oriented energy methods[32, 33], tried to obtain a richer description via using a family of quadrature pairs of even and odd symmetric filters. Interestingly, as shown in the Figure6(c), most of wild animal contours, e.g. We also evaluate object proposals on the MS COCO dataset with 80 object classes and analyze the average recalls from different object classes and their super-categories.
