Problems of dataset creation for light source estimation
E. I. Ershov, A. V. Belokopytov, A. V. Savchik
The paper describes our experience collecting a new dataset for the light source estimation problem in a single image. The analysis of existing color targets is presented along wit…
1-point RANSAC for Circular Motion Estimation in Computed Tomography (CT)
Mikhail O. Chekanov, Oleg S. Shipitko, Egor I. Ershov
This paper proposes a RANSAC-based algorithm for determining the axial rotation angle of an object from a pair of its tomographic projections. An equation is derived for calculatin…
Multiple Light Source Dataset for Colour Research
Anna Smagina, Egor Ershov, Anton Grigoryev
We present a collection of 24 multiple object scenes each recorded under 18 multiple light source illumination scenarios. The illuminants are varying in dominant spectral colours,…
On the use of FHT, its modification for practical applications and the structure of Hough image
M. Aliev, E. I. Ershov, D. P. Nikolaev
This work focuses on the Fast Hough Transform (FHT) algorithm proposed by M.L. Brady. We propose how to modify the standard FHT to calculate sums along lines within any given range…
Fast Hough Transform and approximation properties of dyadic patterns
E. I. Ershov, S. M. Karpenko
Hough transform is a popular low-level computer vision algorithm. Its computationally effective modification, Fast Hough transform (FHT), makes use of special subsets of image matr…
