Background. It is necessary to measure the speed of the paper pulp on paper machines. Optical measurement methods can be used to measure the paper flow rate. The aim of the work is to improve the accuracy of the cross-correlation method of speed measurement by equalizing the computational domain.
Materials and methods. The article uses modern methods of digital image processing.
Results. The principles of improving the standard cross-correlation method for measuring the velocity of fluid flows are substantiated.
Conclusions. Studies confirm the applicability of these methods to improve the standard cross-correlation method.
