Template Matching Using Improved Rotations Fourier Transform Method [PDF]
International Journal of Electronics and Telecommunications, 2022 Template matching is a process to identify and localize a template image on an original image. Several methods are commonly used for template matching, one of which uses the Fourier transform. This study proposes a modification of the method by adding an

Mixed problem for the singular partial differential equation of parabolic type
Karpatsʹkì Matematičnì Publìkacìï, 2018 The scheme for solving of a mixed problem is proposed for a differential equation \[a(x)\frac{\partial T}{\partial \tau}= \frac{\partial}{\partial x} \left(c(x)\frac{\partial T}{\partial x}\right) -g(x)\, T\] with coefficients $a(x)$, $g(x)$ that are the
