Fast computation of accurate Zernike moments
Journal of Real-Time Image Processing, 2007Zernike polynomials are continuous orthogonal polynomials defined in polar coordinates over a unit disk. Zernike moment’s computation using conventional methods produced two types of errors namely approximation and geometrical. Approximation errors are removed by using exact Zernike moments.

Computing Accurate Correspondences across Groups of Images
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010Groupwise image registration algorithms seek to establish dense correspondences between sets of images. Typically, they involve iteratively improving the registration between each image and an evolving mean. A variety of methods have been proposed, which differ in their choice of objective function, representation of deformation field, and optimization

A Fast and Accurate Algorithm for Computing SLERP
Journal of Graphics, GPU, and Game Tools, 2011Abstract The SLERP of quaternions is a common operation in keyframe animation. The operation can be a significant bottleneck in an animation-heavy application. The standard implementation of SLERP for an FPU typically involves trigonometric function evaluations, divisions, and branching.

Accurate Atom-Mapping Computation for Biochemical Reactions
Journal of Chemical Information and Modeling, 2012The complete atom mapping of a chemical reaction is a bijection of the reactant atoms to the product atoms that specifies the terminus of each reactant atom. Atom mapping of biochemical reactions is useful for many applications of systems biology, in particular for metabolic engineering where synthesizing new biochemical pathways has to take into ...

Fast and Accurate Bessel Function Computation
2009 19th IEEE Symposium on Computer Arithmetic, 2009The Bessel functions are considered relatively difficult to compute. Although they have a simple power series expansion that is everywhere convergent, they exhibit approximately periodic behavior which makes the direct use of the power series impractically slow and numerically unstable.

An Accurate Vertex Normal Computation Scheme
2006There are a number of applications in computer graphics and computer vision that require the accurate estimation of normal vectors at arbitrary vertices on a mesh surface. One common way to obtain a vertex normal over such models is to compute it as a weighted sum of the normals of facets sharing that vertex. But numerical tests and asymptotic analysis

Accurate Computations for Some Classes of Matrices
2014A square matrix is called a P-matrix if all its principal minors are positive. Subclasses of P-matrices with many applications are the nonsingular totally positive matrices and the nonsingular M-matrices. For diagonally dominant M-matrices and some subclasses of nonsingular totally nonnegative matrices, accurate methods for computing their singular ...

HOW ACCURATE IS COMPUTER-AIDED DIAGNOSIS?
The Lancet, 1989A computer program for diagnosis of acute abdominal pain (CAD-A) was compared with an amended program (DIAG) and with clinical performance. The programs were tested at three Scottish hospitals, representing a range of practice, in 6962 cases. Accuracy of CAD-A lay in the range 48-59%, and of DIAG 56-62%. Clinical accuracy was constant at 65%.
