GrabCut-Based Human Segmentation in Video Sequences
In this paper, we present a fully-automatic Spatio-Temporal GrabCut human segmentation methodology that combines tracking and segmentation. GrabCut initialization is performed by a HOG-based subject detection, face detection, and skin color model. Spatial information is included by Mean Shift clustering whereas temporal coherence is considered by the historical of Gaussian Mixture Models. Moreo...
متن کاملModified GrabCut for human face segmentation
Image segmentation; Human face segmentation; Face position detection; GrabCut; 3D human model fitting Abstract GrabCut is a segmentation technique for 2D still color images, which is mainly based on an iterative energy minimization. The energy function of the GrabCut optimization algorithm is based mainly on a probabilistic model for pixel color distribution. Therefore, GrabCut may introduce un...
متن کاملSkeleton-based Temporal Segmentation of Human Activities from Video Sequences
This paper presents a new multi-step, skeleton-based approach for the temporal segmentation of human activities from video sequences. Several signals are first extracted from a skeleton sequence. These signals are then segmented individually to localize their cyclic segments. Finally, all individual segmentations are merged with respect to the global set of signals. Our approach requires no pri...
متن کاملA volume segmentation approach based on GrabCut
The representation of an image as a flow network has gained an increased interest in research for the 2D and 3D segmentation field. One of these segmentation approaches consists in applying a minimum cut algorithm to separate the image in background and foreground. The most remarkable algorithm to segment a 2D image using this approach is GrabCut. This article presents a novel segmentation of 3...
متن کاملSemantic Segmentation using GrabCut
This work analyzes how to utilize the power of the popular GrabCut algorithm for the task of pixel-wise labeling of images, which is also known as semantic segmentation and an important step for scene understanding in various application domains. In contrast to the original GrabCut, the aim of the presented methods is to segment objects in images in a completely automatic manner and label them ...
