Abstract
This paper deals with the technology of forming adaptive filters to eliminate distortions such as defocus on images recorded using mobile devices. The main purpose of the development is to ensure a sufficiently high quality of the distortion correction with minimal computational costs. The blind parametric identification of the model with a radially symmetric quadratic-exponential frequency response is used to adjust the filter parameters. The algorithm, the pseudo-code of the program and the results of experiments demonstrating the effectiveness of the proposed approach are given.
Highlights
In recent years, there has been an increasing interest in the problem of processing images recorded by mobile devices
Hopes are associated with the improvement of the technology for creating diffractive optical elements (DOEs), in particular, with the creation of lenses based on the Fresnel imaging lens. [3], [4]
Perhaps the creation of compact mobile applications of digital image processing, which to some extent can compensate for this shortcoming, would give a new impetus to the construction of mobile devices based on DOE
Summary
There has been an increasing interest in the problem of processing images recorded by mobile devices. In the paper [5], the traditional technology of component-wise processing of colour RGB images within the framework of the described SE-filter model was implemented.
