This paper presents a GPU-based stereo matching system with good performance in both accuracy and speed. The matching cost volume is initialized with an AD-Census measure, aggregated in dynamic cross-based regions, and updated in a scanline optimization framework to produce the disparity results. Various errors in the disparity results are effectively(More)
In this paper, we present a unified framework for model-ing intrinsic properties of face images for recognition. It is based on the quotient image (QI) concept, in particular Under this framework, we generalize these previous works into two new algorithms: (1) Non-Point Light Quotient Image (NPL-QI) extends QI to deal with non-point light sources by(More)
In this paper, we introduce the concept of Self-Quotient Image (SQI) for robust face recognition under varying lighting conditions. It is based on the Quotient Image method [4][5] to achieve lighting invariant. However, the SQI has three advantages: (1) It needs only one face image for extraction of intrinsic lighting invariant property of a face while(More)
Human neural stem cells hold great promise for research and therapy in neural disease. We describe the generation of integration-free and expandable human neural progenitor cells (NPCs). We combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram epithelial-like cells from human urine into NPCs(More)
The reliability of facial recognition techniques is often affected by the variation of illumination, such as shadows and illumination direction changes. In this paper, we present a novel framework, called the self-quotient image, for the elimination of the lighting effect in the image. Although this method has a similar invariant form to the quotient image(More)
Damage to the medial temporal lobe impairs the encoding of new memories and the retrieval of memories acquired immediately before the damage in human. In this study, we demonstrated that artificial visuoauditory memory traces can be established in the rat auditory cortex and that their encoding and retrieval depend on the entorhinal cortex of the medial(More)
Cuprizone (CPZ) is a neurotoxic agent acting as a copper chelator. In our recent study, C57BL/6 mice given dietary CPZ (0.2%) showed impairments in spatial working memory, social interaction, and prepulse inhibition. These abnormalities are reminiscent of certain schizophrenia symptoms and are not likely due to damage in the whole brain or in any single(More)
Forkhead box O3 (FoxO3a) is a forkhead family transcription factor playing important roles in non-neuronal differentiation, metabolism, proliferation, and survival, but its role in neuronal differentiation remains unclear. In the present study, we investigated the role of FoxO3a in neuronal differentiation and its underlying mechanisms. Our results showed(More)
MicroRNAs (miRNAs) are endogenously expressed small, non-coding transcripts that regulate protein expression. Substantial evidences suggest that miRNAs are enriched in central nervous system, where they are hypothesized to play pivotal roles during neural development. In the present study, we analyzed miRNAs expression in mice cerebral cortex and(More)
