In this paper, we study the influence of noise on images of different colors and determine the difference in the level of these influences. Values characterizing the signal-to-noise ratio in decibels are obtained. The comparison of the values obtaine

The use of standard instruments (colorimeters) when measuring the color coordinates and chromaticity of multicolored objects and having relatively large dimensions is practically impossible. This is due to the fact that ordinary colorimeters, no matt

It is known that the stroke color of a ballpoint pen changes over time (fades), which means that by the color change of the stroke, you can determine the age of the stroke, and therefore the authenticity of the document. It can be noted that the use
