One of their drawbacks is that bounding boxes usually cannot provide accurate object localization. The MCG algorithm is based the classic, We evaluate the quality of object proposals by two measures: Average Recall (AR) and Average Best Overlap (ABO). We present Convolutional Oriented Boundaries (COB), which produces multiscale oriented contours and region hierarchies starting from generic image classification Convolutional Neural Networks (CNNs). 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 dataset is more challenging due to its large variations of object categories, contexts and scales. We believe our instance-level object contours will provide another strong cue for addressing this problem that is worth investigating in the future. Given trained models, all the test images are fed-forward through our CEDN network in their original sizes to produce contour detection maps. B.C. Russell, A.Torralba, K.P. Murphy, and W.T.

Fully convolutional networks for semantic segmentation. Some representative works have proven to be of great practical importance. Felzenszwalb et al. 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]. It is likely because those novel classes, although seen in our training set (PASCAL VOC), are actually annotated as background. Different from previous low-level edge detection, our algorithm focuses on detecting higher-level object contours.
