What is a "SHOT"? What we are looking for Shot – an abrupt change in the scene i.e. change of scene, change of camera angle (change of active camera). Shot detection in video is also called – video segmentation. If we compare stills image segmentation to video segmentation, then the homogeneous regions in image are homogeneous sequences in video and boundaries in images are actually the shots i...

In this work, we present a new computer vision task named video object of interest segmentation (VOIS). Given and target image interest, our objective is to simultaneously segment track all objects in the that are relevant image. This problem combines traditional with an additional indicating content users concerned with. Since no existing dataset perfectly suitable for task, specifically const...

In this paper we present our system for human-in-theloop video object segmentation. The backbone of our system is a method for one-shot video object segmentation [3]. While fast, this method requires an accurate pixel-level segmentation of one (or several) frames as input. As manually annotating such a segmentation is impractical, we propose a deep interactive image segmentation method, that ca...

Image segmentation provides a powerful semantic description of video imagery essential in image understanding and efficient manipulation of image data. In particular, segmentation based on image motion defines regions undergoing similar motion allowing image coding system to more efficiently represent video sequences. This paper describes a general iterative framework for segmentation of video ...

Object segmentation from a video stream is an essential task in video processing and forms the foundation of scene understanding, object-based video encoding (e.g. MPEG4), and various surveillance and 2D-topseudo-3D conversion applications. The task is difficult and exacerbated by the advances in video capture and storage. Increased resolution of the sequences requires development of new, more ...

Spatio-temporal segmentation of video sequences attempts to extract backgrounds and independent objects in the dynamic scenes captured in the sequences. It is an essential step of video analysis. It has important applications in video coding, video logging, indexing and retrieval, and more generally in scene interpretation and video understanding. We classify spatio-temporal grouping techniques...

Object-based video and audio data representations, such as MPEG-4, enable unprecedented functionalities of content access and manipulation. In fulfilling the potential, video object segmentation and content-based search techniques remain as two challenging tasks. In this twopart paper, we present an integrated approach for semantic video object segmentation and retrieval. In the first part, we ...

Semi-supervised video object segmentation is a task of propagating instance masks given in the first frame to entire video. It challenging since it usually suffers from heavy occlusions, large deformation, and variations objects. To alleviate these problems, many existing works apply time-consuming techniques such as fine-tuning, post-processing, or extracting optical flow, which makes them int...
