Purpose: invariance and a mobile finger image method with rotation, which relatively quickly pass through, determines that a radius of a circle is arranged to the rotation with an initial fingerprint or a transformation impression of the hand, three characteristic points including impression of the ...

3. In this paper a method for wavelet transform based on translation invariant in the image denoising area is researched. 平移不变量小波变换在图像降噪中的应用,主要通过阈值方法来有效的降低图像的噪声,但它的结果中会出现诸如伪吉布斯现象之类的情况。
A method is presented for efficiently maintaining and searching a database of three-dimensional models so they can be reliably recognized from arbitrary tw... PC Wayner - IEEE Computer Society Conference on Computer Vision & Pattern Recognition 被引量: 71发表: 1991年 Feature-Based Object Recogniti...
One method to suppress such artifacts, termed "cycle spinning" by Coifman, is to "average out" the translation dependence. For a range of shifts, one shifts the data (right or left as the case may be), De-Noises the shifted data, and then unshifts the de-noised data. Doing this for...
We derive a Fast Multipole Method (FMM) where a low-rank approximation of the kernel is obtained using the Empirical Interpolation Method (EIM). Contrary to classical interpolation-based FMM, where the interpolation points and basis are fixed beforehand, the EIM is a nonlinear approximation method...
Although conceptually simple, the method for setting λ is analytically intractable due to the lack of explicit functional form of the estimator. However, with appropriate pre-computation, the method can be implemented by table look-up. In Section 2, the cost function is given and the iterative...
In this peper it is mainly introduced that the 3-D picture transformation, such as rotation andshift, is carried out by the author using the method of vector algebra to construct compound object. 文章主要介绍作者在三维图形系统GP3D的设计开发中,以矢量代数的方法对三维图形元素作直接旋转、平移等变...
A method for object recognition that is invariant underntranslation, rotation and scaling is addressed. The first step of thenmethod (pre-processing) takes into account the invariant properties ofnthe normalized moment of inertia and a novel coding that extractsntopological object characteristics. The...
we propose a novel Projective Polar Transform (PPT) based image registration method that is robust to translation, scale, and rotation and yields high accu... Matungka, R,Zheng, Y. F,Ewing, R. L - IEEE International Conference on Acoustics 被引量: 9发表: 2009年 FPGA based accelerated or...
