Remote Sensing is a technique to obtain data from objects without physical contact using sensors. If it is performed by hyperspectral sensors, then is possible to have a large number of bands that allows many applications. In this case, a large amount of data needs to be processed and analyzed, and therefore the practical use of these images have challenges with storage, transport and processing time...
This paper proposes a method for synthesizing free viewpoint video which is captured by uncalibrated multiple cameras. Each cameras are allowed to be zoomed and rotated freely during capture. Neither intrinsic nor extrinsic parameters of our cameras are known. Projective grid space (PGS), which is the 3D space defined by the epipolar geometry of two basis cameras, is employed for calibrating dynamic...
This paper proposes a novel method for calibrating multiple hand-held cameras target for diminished reality application. Our method does not require any special markers or information about camera parameters. projective grid space (PGS) which is 3D space defined by epipolar geometry of two basis cameras is used for dynamic cameras calibration. Geometrical relations among cameras in PGS are obtained...
This paper proposes a vision-based method for detecting the positions of fingertips of a hand playing a guitar. We detect the skin color of a guitar player's hand by using on-line adaptation of color probabilities and a Bayesian classifier which can cope with considerable illumination changes and a dynamic background. The results of hand segmentation are used to train an artificial neural network...
Analysis of skin inner tissue in three-dimensional (3-D) has great significance for cosmetics industry. In our research work, we developed a method of automatically extracting the surface of skin inner tissue from volumetric confocal microscope images, as well as reconstructing a 3-D model. The proposed method is derived from 3-D active contour model. Active contour model is an image segmentation...
