We present a novel hierarchical MRFs optimization method for dense and deformable motion extraction in dynamic scenes. In particular, this hierarchical MRFs structure consists of two layers, the segmentation and the correspondence layer. Firstly, dynamic RGB-D foreground data is segmented through a pixel-level MRF in the segmentation layer. Subsequently,(More)
NAD(P)H quinine oxidoreductase 1 (NQO1) enzyme plays a crucial role in the protection against oxidative stress. The polymorphism of NQO1 C609T has been implicated in the development of hepatocellular carcinoma (HCC). However, the findings were inconsistent due to different ethnicity, sample size, and source of controls in individual studies. To better(More)
In this paper, we propose a novel global object descriptor, so-called Viewpoint oriented Color-Shape Histogram (VCSH), which combines 3D object’s color and shape features. The descriptor is efficiently used in a real-time textured/textureless object recognition and 6D pose estimation system, while also applied for object localization in a coherent semantic(More)
In this paper, we present an object recognition and pose estimation framework consisting of a novel global object de-scriptor, so called Viewpoint oriented Color-Shape Histogram (VCSH), which combines object's color and shape information. During the phase of object modeling and feature extraction , the whole object's color point cloud model is built by(More)
Multiple people tracking is an important component for different tasks such as video surveillance and human-robot interaction. In this paper, a global optimization approach is proposed for long-term tracking of an a priori unknown number of targets, particularly aim to improve the robustness in case of complex interaction and mutual occlusion. With a(More)
— An important prerequisite for intelligent robots to effectively perform daily tasks in indoor environments is an advanced environment model. Not only should this model contain metric level information about the geometry of the perceived environment, it should also provide abstract level information, such as topology and objects, so as to benefit high(More)
An important ability for mobile robots is to process multiple tasks in complex environments. Since the sensor resources on a robot are limited, it is necessary to distribute the sensors attention to different tasks along the time scale. This paper proposes a temporal attention control method which aims at detecting multiple objects and estimating their(More)
