"GrabCut” -- interactive foreground extraction using iterated graph cuts
- ACM TRANS. GRAPH
, 2004
"... The problem of efficient, interactive foreground/background segmentation in still images is of great practical importance in image editing. Classical image segmentation tools use either texture (colour) information, e.g. Magic Wand, or edge (contrast) information, e.g. Intelligent Scissors. Recently ..."

AUTOMATIC FOREGROUND EXTRACTION IN VIDEO
"... This paper presents an automatic and efficient system for ex-tracting dynamic objects of interest from videos. We take advantage of a saliency map and an optimization-based seg-mentation algorithm to extract the foreground objects auto-matically in some key frames. Then, the segmentation re-sults in ..."

REGION-BASED FOREGROUND EXTRACTION
"... We propose a region-based method to extract foreground regions from colour video sequences. The foreground region is decided by voting with scores from background subtraction to the sub-regions by graph- based segmentation. Experiments show that the proposed algorithm improves on conventional approa ..."

RANGE-ENHANCED ACTIVE FOREGROUND EXTRACTION
"... We describe a new technique that uses active scene illumination to perform foreground-background segmentation and recover partial HDR information. We explore the fact that relative tones can be recovered by varying illumination intensity, without knowing the camera response function. In our approach ..."

Automatic foreground extraction of head shoulder images
- In Computer Graphcis International (Springer LNCS 4035
, 2006
"... Abstract. Most existing techniques of foreground extracting work only in interactive mode. This paper introduces a novel algorithm of auto-matic foreground extraction for special object, and verifies its effective-ness with head shoulder images. The main contribution of our idea is to make the most ..."

A Multi-Criteria Model for Robust Foreground Extraction
"... Numerous methods are currently available for motion detection using background modeling and subtraction. However, there are still many challenges to take into account such as moving shadows, illumination changes, moving background, relocation of background objects, and initialization with moving obj ..."

objects. This paper provides a new background subtraction algorithm that aggregates the classification results of several foreground extraction techniques based on UV color deviations, probabilistic gradient information and vector deviations, in order to produce a single decision that is more robust
Information-Fusion-Based Foreground Extraction For Video Streams
"... The new MPEG-4 video coding standard consists of object based coding schemes for multimedia and enables content based functionalities. Video objects in still pictures or video sequences should be first identified before the encoding process starts. An algorithm based on information fusion, which can ..."

Multi-Resolution Illumination Compensation for Foreground Extraction
- In Proceedings of the 16th IEEE International Conference on Image Processing (ICIP'09
, 2009
"... Illumination changes may lead to false foreground (FG) segmen-tation and tracking results. Most of the existing FG extraction algo-rithms obtain a background (BG) estimation from temporal statisti-cal parameters. Such algorithms consider a quasi-static BG which does not change but slowly. Therefore, ..."

GRAPH-BASED FOREGROUND EXTRACTION IN EXTENDED COLOR SPACE
"... We propose a region-based method to extract semantic foreground regions from color video sequences with static backgrounds. First, we introduce a new distance measure for background subtraction which is robust against shadows. Then the foreground region is extracted with a graph-based region segment ..."
