In the 1980s, an electromagnetic infrared method was initially developed at the US Air Force Academy (USAFA) and the University of Colorado at Colorado Springs (UCCS) that produced the first images of EM fields made by an Infrared camera measuring the heating of absorbing materials. In the 1990s, this field imaging method was then enhanced by the F...
We present a new theoretical approach to the processing ofmultidimensional and multicomponent images based on the theory of commutativehypercomplex algebras, which generalize the algebra of complex numbers.The main goal of the paper is to show that commutative hypercomplex numberscan be used in multichannel image processing in a natural and effecti...

Structured Illumination Microscopy (SIM) is an imaging technique for achieving both super-resolution (SR) and optical sectioning (OS) in wide-field microscopy. It consists in illuminating the sample with periodic patterns at different orientations and positions. The resulting images are then processed to reconstruct the observed object with SR and/...
This paper is devoted to the investigation and development of the round timber batch measurement technique on the basis of abuts detection and calculation of their diameters. The algorithm of abuts contours detection and refinement relies on the modified radial symmetry object detection. The meanshift clustering, Delaunay triangulation, Boruvka’s m...
In the framework of NATO task group SET 226 on turbulence mitigation techniques for OA systems, a trial was conducted in the premises of RDDC-Valcartier, using indoor and outdoor facilities in September 2016. Images data sets were collected under various turbulence conditions, both controllable (indoor) and natural (outdoor). The imagery of this tr...
The combustion of aluminum particles is a key factor for solid-propellant propulsion in terms of performance and stability. An automatic detection of droplets in Al-PLIF image was developed. The "Maximally Stable Extremal Regions" detection method is evaluated on two image sets previously obtained at 1.0 and 1.5 MPa. The method shows good detection...
On April 25, 2019, Vladimir Chernov celebrated his 70th birthday, Doctor of Physics and Mathematics, Chief Researcher at the Laboratory of Mathematical Methods of Image Processing of the Image Processing Systems Institute of the Russian Academy of Sciences (IPSI RAS), a branch of the Federal Science Research Center "Crystallography and Photonics RA...
Deep learning techniques are becoming increasingly important to solve a number of image processing tasks. Among common algorithms, Convolutional Neural Networks and Recurrent Neural Networks based systems achieve state of the art results on satellite and aerial imagery in many applications. While these approaches are subject to scientific interest,...
