We address the problem of instance-level semantic segmentation, which aims at jointly detecting, segmenting and classifying every individual object in an image. In this context, existing methods typically propose candidate objects, usually as bounding boxes, and directly predict a binary mask within each such proposal. As a consequence, they cannot recover from errors in the object candidate generation...
We address the problem of object segment proposal generation, which is a critical step in many instance-level semantic segmentation and scene understanding pipelines. In contrast to prior works that predict binary segment masks from images, we take an alternative refinement approach to improve the quality of a given segment candidate pool. In particular, we propose an efficient deep network that learns...
This paper presents a context-aware object proposal generation method for stereo images. Unlike existing methods which mostly rely on image-based or depth features to generate object candidates, we propose to incorporate additional geometric and high-level semantic context information into the proposal generation. Our method starts from an initial object proposal set, and encode objectness for each...
We tackle the problem of semantic segmentation of dynamic scene in video sequences. We propose to incorporate foreground object information into pixel labeling by jointly reasoning semantic labels of super-voxels, object instance tracks and geometric relations between objects. We take an exemplar approach to object modeling by using a small set of object annotations and exploring the temporal consistency...
