Facial symmetry can be used as the prior knowledge to supplement shape information in face techniques such as shadow compensation or pose correction. In this paper, we demonstrate the application of the facial symmetry assumption in 3D face reconstruction. We horizontally mirror non-frontal illumination face images and align them to the original images(More)
In this paper, we present a new sparse to dense 3D face reconstruction method using monocular video sequences. Structure from motion (SFM) is an effective method to reconstruct sparse 3D facial shape; however, its performance degrades drastically when tracking errors caused by self-occlusion or image noise exist. To address the problem, we propose a(More)
In recent years, the collapse of critical components due to over heating has been a big issue in the micro electro-mechanical system. The magnetocaloric properties of magnetic fluid can be use to remove the undesired heat generated in the system without any mechanical moving parts.

A gram-negative bacterium designated BN30T, which is motile with a polar flagellum, non-endospores forming, oxidase- and catalase-positive, was isolated from soybean root nodule. The organism is facultative anaerobic and surface-wrinkled rod. It can grow at 10–40 °C, pH 6–8 and 6 % (w/v) NaCl. BLASTn search based on 16S rRNA gene sequence revealed that the(More)
Multi-illumination training images are usually used in robust face recognition against light variation.Usually a large number of training images are taken under sophisticated imaging system. There definitely exists a large amount of redundancy in these images. Can we pick out several representative samples from them as training images instead of using the(More)
We describe a novel variational level set based method for delineating the sub thalamic nucleus (STN) region of human brains from magnetic resonance (MR) images. Based on the understanding of specific imaging characteristic of STN, we apply a narrow band limitation in the region-based energy function for localizing the STN from initial contour information(More)
