crossproduct does 2D and 3D geometry calculations in Python. It builds on the Shapely package by including additional geometric objects (such as vectors, lines and polyhedrons) and by extending the ...

# Cannot calculate the even root for negative product. # Frequently they are restricted to being positive. if product < 0 and len(args) % 2 == 0: raise ...

In this paper we present a survey of various algorithms for computing matrix geometric means and derive new second-order optimization algorithms to compute the Karcher mean. These new algorithms are ...

Computational geometry is a branch of computer science that studies algorithms for solving ... in a language that supports geometric and spatial libraries, such as Python, C++, or Java.

To optimize the performance of non local mean image denoising algorithms, the similarity of image blocks in this algorithm is now integrated into the evaluation calculation steps of image block ...

In this research, background modelling of Geometric Mean (GM) based lognormal distribution of each pixel is considered, followed by K-mean clustering algorithm is used to separate background from ...
