Ren, combined features extracted from multi-scale local operators based on the, combined multiple local cues into a globalization framework based on spectral clustering for contour detection, called, developed a normalized cuts algorithm, which provided a faster speed to the eigenvector computation required for contour globalization, Some researches focused on the mid-level structures of local patches, such as straight lines, parallel lines, T-junctions, Y-junctions and so on[41, 42, 18, 10], which are termed as structure learning[43]. To automate the operation-level monitoring of construction and built environments, there have been much effort to develop computer vision technologies. Object Contour Detection extracts information about the object shape in images. Early research focused on designing simple filters to detect pixels with highest gradients in their local neighborhood, e.g. Object Contour Detection with a Fully Convolutional Encoder-Decoder Network.

The VOC 2012 release includes 11530 images for 20 classes covering a series of common object categories, such as person, animal, vehicle and indoor. The same measurements applied on the BSDS500 dataset were evaluated. Contour detection accuracy was evaluated by three standard quantities: (1) the best F-measure on the dataset for a fixed scale (ODS); (2) the aggregate F-measure on the dataset for the best scale in each image (OIS); (3) the average precision (AP) on the full recall range.

Observing the predicted maps, our method predicted the contours more precisely and clearly, which seems to be a refined version. For RS semantic segmentation, two types of frameworks are commonly used: fully convolutional network (FCN)-based techniques and encoder-decoder architectures. Concerned with the imperfect contour annotations from polygons, we have developed a refinement method based on dense CRF so that the proposed network has been trained in an end-to-end manner. J.J. Kivinen, C.K. Williams, and N.Heess. The dense CRF optimization then fills the uncertain area with neighboring instance labels so that we obtain refined contours at the labeling boundaries (Figure3(d)). This is the code for arXiv paper Object Contour Detection with a Fully Convolutional Encoder-Decoder Network by Jimei Yang, Brian Price, Scott Cohen, Honglak Lee and Ming-Hsuan Yang, 2016.

We borrow the ideas of full convolution and unpooling from above two works and develop a fully convolutional encoder-decoder network for object contour detection. 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. [19] and Yang et al.

The proposed multi-tasking convolutional neural network did not employ any pre- or postprocessing step. is applied to provide the integrated direct supervision by supervising each output of upsampling. The thinned contours are obtained by applying a standard non-maximal suppression technique to the probability map of contour. Given image-contour pairs, we formulate object contour detection as an image labeling problem. Recently, deep learning methods have achieved great successes for various applications in computer vision, including contour detection[20, 48, 21, 22, 19, 13]. TableII shows the detailed statistics on the BSDS500 dataset, in which our method achieved the best performances in ODS=0.788 and OIS=0.809. 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. refine object segments,, K.Simonyan and A.Zisserman, Very deep convolutional networks for 13 papers with code The ground truth contour mask is processed in the same way.

Fig. We also compared the proposed model to two benchmark object detection networks; Faster R-CNN and YOLO v5. L.-C. Chen, G.Papandreou, I.Kokkinos, K.Murphy, and A.L. Yuille. Felzenszwalb et al. 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. By clicking accept or continuing to use the site, you agree to the terms outlined in our. For example, the standard benchmarks, Berkeley segmentation (BSDS500)[36] and NYU depth v2 (NYUDv2)[44] datasets only include 200 and 381 training images, respectively. Thus the improvements on contour detection will immediately boost the performance of object proposals. The encoder is used as a feature extractor and the decoder uses the feature information extracted by the encoder to recover the target region in the image. Inspired by the success of fully convolutional networks[34] and deconvolutional networks[38] on semantic segmentation, In TD-CEDN, we initialize our encoder stage with VGG-16 net[27] (up to the pool5 layer) and apply Bath Normalization (BN)[28], to reduce the internal covariate shift between each convolutional layer and the Rectified Linear Unit (ReLU). Quantitatively, we present per-class ARs in Figure12 and have following observations: CEDN obtains good results on those classes that share common super-categories with PASCAL classes, such as vehicle, animal and furniture.
