In practice,such as CAD(computer aided design), CAM(computer aided manufacture) and VR(virtual reality),the algorithm can meet the different requests of precision for the three-dimensional body modeling.
An investigation of disinfection quality in 9 hospi-tals showed that qualified rate was 56.84% for disin-fected medical instruments, 62.07% for ultraviolet in-tensity assay and 87.31% for disinfection of body sur-face.
It only need to compute the plane to plane homography,and through the homography3D coordinates of an object can be worked out of the image of the object under the parallel structured light without calibrating camera.
Shape from shading(SFS) is one of the critical techniques to shape recovery in computer vision,which obtains 3-D shape of the visible surface of an object from only one image of it using the shading knowledge in the given picture.
从明暗恢复形状 (shape from shading,简称 SFS)是计算机视觉中三维形状恢复问题的关键技术之一 ,其任务是利用单幅图象中物体表面的明暗变化来恢复其表面三维形状 .
When a function does not belong to such a space, the sampling series may converge, not to the object function but to an "alias" of it, and an aliasing error is said to occur.
This work is motivated from and useful in object-based video coding, where a segmented moving object may have arbitrary shape and block transform coding of this object is needed.
Therefore, it should be an important step in developing a system for automated perspective-independent object recognition.
Our object in this article is to describe the Galerkin scheme and nonlinear Galerkin scheme for the approximation of nonlinear evolution equations, and to study the stability of these schemes.
The new optimality condition doesn't use Luderer's regularity assumption and its Lagrangian multipliers don't depend on the particular elements in the superdifferentials of the object function and constraint functions.
Gindikin that complex analytic objects related to these domains will provide explicit realizations of unitary representations ofH?.
The essential dimension is a numerical invariant of the group; it is often equal to the minimal number of independent parameters required to describe all algebraic objects of a certain type.
For example, if our groupG isSn, these objects are field extensions; ifG=On, they are quadratic forms; ifG=PGLn, they are division algebras (all of degreen); ifG=G2, they are octonion algebras; ifG=F4, they are exceptional Jordan algebras.
This setup comprises well known objects such as framed vector bundles, Higgs bundles, and conic bundles.
In this paper, we will formulate a general (parameter dependent) semistability concept for such triples, which generalizes the classical Hilbert--Mumford criterion, and we establish the existence of moduli spaces for the semistable objects.
Male Wistar rats were treated with both La(NO3)3 and Ce(NO3)3 at doses of 2, 10, and 50 mg/kg body weight.
The experiment of edge detection is made for the images of nature scenery, human body and accumulative raw material, whose result is compared with the one of classical algorithms and showing the robustness of the proposed method.
In order to satisfy the need of diagnoses, based on the characteristic of medical images that a sequence of frames are formed in one body inspection, a new strategy for medical images compression is proposed.
All of the above favors the use of software in the magnetic focused conductivity tomography system (MFCT) to reconstruct the image of conductivity within the human body.
The continuous wavelet transform (CWT) is employed to analyze vibration signals obtained from the motor body.
The traditional snake initial contour should be close to the true boundary of an object of interest in an image; otherwise, an incorrect result will be obtained.
This method however has the disadvantage of low contrast of the cross-sectional pictures of an object.
The coupling intension corresponds with two factors: the structure of an SLM and the position of an object point in the view of an SLM.
With seven major river basins in China as an object of study, this paper is designed to perform a diagnosis of major problems about the transjurisdictional water pollution management in China from three aspects, i.e.
Adaptive Control of an Object with a Delayed Control and Scalar Input-Output Signals
