An Improved Canny Edge Detection Algorithm Based on Type-2 Fuzzy Sets
Ranita Biswas,Jaya Sil +1 more
TL;DR: An algorithm based on the concept of type-2 fuzzy sets to handle uncertainties that automatically selects the threshold values needed to segment the gradient image using classical Canny's edge detection algorithm is proposed.
Journal ArticleDOI
Layer the sphere
Ranita Biswas,Partha Bhowmick +1 more
TL;DR: A novel technique for discretization of a sphere in the integer space is introduced, which gives rise to a set of mathematically accurate, 3D-printable physical voxels up to the desired level of precision.
Book ChapterDOI
On Finding Spherical Geodesic Paths and Circles in ℤ3
Ranita Biswas,Partha Bhowmick +1 more
TL;DR: It is shown that the set of sphere voxels intersected by the real plane always contains a 1-connected cycle passing through s and t, and each voxel in this set lies within an isothetic distance of \(\frac32\) from the concerned plane.
Journal ArticleDOI
On different topological classes of spherical geodesic paths and circles in Z 3
Ranita Biswas,Partha Bhowmick +1 more
TL;DR: This work proposes an efficient integer-based algorithm to compute the discrete spherical geodesic path (DSGP) for any class-and-neighborhood combination, and derives the upper bounds of the distance of a DSGP belonging to each class, from the real sphere and the real plane, for different neighborhood conditions.
Journal ArticleDOI
From prima quadraginta octant to lattice sphere through primitive integer operations
Ranita Biswas,Partha Bhowmick +1 more
TL;DR: The first integer-based algorithm for constructing a well-defined lattice sphere specified by integer radius and integer center is presented, which evolves from a unique correspondence between the lattice points comprising the sphere and the distribution of sum of three square numbers in integer intervals.
