In this paper, we present a new algorithm for RGB-D hand gesture recognition by using multi-attribute sparse representation enforced with group constraints. Firstly, the hand region is segmented from the background according to the depth information. Then, we process all gesture-performing hand region images with PCA to reduce the feature ...

In this paper, we propose a novel disocclusion region recovery approach for two-view to n-view conversion system. Although the topic of view synthesis has been exhaustively studied for decades, a reliable disocclusion region recovery approach, an indispensable issue in synthesizing realistic content of virtual view, is still under research. The ...

This paper presents a multi-attribute sparse coding approach for facial expression recognition by regarding Action-Units (AUs) as attributes. AUs describe the movements of individual facial muscles, which are detected from corresponding attribute masks in this work. They can not only be used to de scribe group property which enforces basis ...

In this paper, we develop a fast and accurate 3D object alignment system which can be applied to detect objects and estimate their 3D pose from a depth image containing cluttered background. The proposed 3D alignment system consists of two main algorithms: the first is the 3D detection algorithm to ...

We propose a novel framework for reconstructing 3Dliver vessel model from CT images. The proposed algorithm consists of vessel detection, vessel tree reconstruction and vessel radius estimation. First, we employ the tubular-filter based approach to detect vessel structure and construct the minimum spanning tree to bridge all the gaps between ...

This paper presents a novel blind image deconvolution algorithm for motion deblurring from a single blurred image. We propose a unified framework for both blur kernel estimation and non-blind image deconvolution by using bilateral filtering (BF) and a new image deconvolution algorithm, called the Gradient Attenuation Richardson-Lucy (GARL) algorithm. In ...

In this paper, we propose an automatic facial expression exaggeration system, which consists of face detection, facial expression recognition, and facial expression exaggeration components, for generating exaggerated views of different expressions for an input face video. In addition, the parallelized algorithms for the automatic facial expression exaggeration system are developed ...

We propose a novel algorithm to generate a virtual-view video from a video-plus-depth sequence. The proposed method enforces the spatial and temporal consistency in the disocclusion regions by formulating the problem as an energy minimization problem in a Markov random field (MRF) framework. At the system level, we first recover ...

A novel component-level dictionary learning framework that exploits image/video group characteristics based on sparse representation is introduced in this paper. Unlike the previous methods that select the dictionaries to best reconstruct the data, we present an energy minimization formulation that jointly optimizes the learning of both sparse dictionary and component-level ...

With the large variations in appearance for different kinds of defects in Printed Circuit Boards (PCBs), conventional rule-based inspection algorithms become insufficient for detecting and classifying defects. In this study, an automated PCB inspection system based on statistical learning strategies is developed. First, the partial Hausdorff distance is used to ...

Markov random field models provide a robust formulation for the stereo vision problem of inferring three-dimensional scene geometry from two images taken from different viewpoints. One of the most advanced algorithms for solving the associated energy minimization problem in the formulation is belief propagation (BP). Although BP provides very accurate ...

Torticollis, also called wryneck, is a clinical sign or symptom that could be the result of a variety of possible disorders. Among the etiologies, congenital muscular torticollis (CMT) with impairment of the sternocleidomastoid (SCM) is the most frequent cause of torticollis in infants. Infants with CMT have the symptom of ...

In this paper, we present a system for segmenting the 3D liver region from CT images and reconstructing its 3D model. The segmentation is accomplished in 3-D space which is extended from the user controlled 2-D random walker technique and implemented by a slice-section method. After obtaining the 3D liver ...

In this paper, we propose a novel approach to reconstructing depth map from a video sequence, which not only considers geometry coherence but also temporal coherence. Most of the previous methods of reconstructing depth map from video are based on the assumption of rigid motion, thus they cannot provide satisfactory ...

CT-MRI registration is a common processing procedure for clinical diagnosis and therapy. We propose a novel K-space affine image registration algorithm via Fourier moment matching. The proposed algorithm is based on estimating the affine matrix from the moment relationship between the corresponding Fourier spectrums. This estimation strategy is very robust ...
