An algorithm for the restoration of blurred image obtained with a rotating camera tilted to the horizon [PDF]
Компьютерная оптика, 2020 This work is a continuation of the authors’ previous publications, in which the restoration of images obtained with a horizontally rotating camera was considered.

ConvMAE: Masked Convolution Meets Masked Autoencoders [PDF]
arXiv.org, 2022 Vision Transformers (ViT) become widely-adopted architectures for various vision tasks. Masked auto-encoding for feature pretraining and multi-scale hybrid convolution-transformer architectures can further unleash the potentials of ViT, leading to state ...

Mathematical Structures in Computer Science, 2021 AbstractWe show how concurrent quantales and concurrent Kleene algebras arise as convolution algebras of functions from relational structures with two ternary relations that satisfy relational interchange laws into concurrent quantales or Kleene algebras, among others.

A New Computational Approach to Estimate the Subdivision Depth of
IEEE Access, 2020 The $n$ -ary subdivision scheme has traditionally been designed to generate smooth curve and surface from control polygon. In this paper, we propose a new subdivision depth computation technique for $n$ -ary subdivision scheme.

Photonics, 2019 The gyrator transform (GT) is used for images processing in applications of light propagation. We propose new image processing operators based on the GT, these operators are: Generalized shift, convolution and correlation.

Approximate Multiplier based on Low power and reduced latency with Modified LSB design [PDF]
E3S Web of Conferences, 2023 The devised approximation multiplier can adapt the precision and processing power needed formul triplication sat run-time based on the needs of the user. To decrease error distance, we also suggest a straight forward error compensation circuit. There are

Convolution of n-dimensional Tempered Ultradistributions and Field Theory [PDF]
, 2003 In this work, a general definition of convolution between two arbitrary Tempered Ultradistributions is given. When one of the Tempered Ultradistributions is rapidly decreasing this definition coincides with the definition of J. Sebastiao e Silva.

PSTNet: Point Spatio-Temporal Convolution on Point Cloud Sequences [PDF]
International Conference on Learning Representations, 2022 Point cloud sequences are irregular and unordered in the spatial dimension while exhibiting regularities and order in the temporal dimension. Therefore, existing grid based convolutions for conventional video processing cannot be directly applied to ...

Fuzzy Sets and Systems, 2018 We propose two convolution operations on the set of functions between two bounded lattices and investigate the algebraic structure they constitute, in particular the lattice laws they satisfy. Each of these laws requires the restriction to a specific subset of functions, such as normal, idempotent or convex functions. Combining all individual results,
