Abstract:
In this work, the 40000 thresholds of the visibility of spatio-temporal sinusoidal variations necessary to determine the artefacts that a human perceives were measured by a new method using different spatial sizes and temporal modulation rates. A multidimensional model of human contrast sensitivity in modern conditions of video content presentation is proposed based on new large-scale data obtained during the experiment.
Central Vision:
The 27840 thresholds of the visibility of spatio-temporal sinusoidal variations that a human perceives were measured by a new method using different spatial sizes and temporal modulation rates.
The coefficients of the defined approximation polynomials of sl(k, f, 120) derivatives.

Peripheral Characteristics of Human Vision:
1760 values of contrast thresholds for the peripheral region of the human visual system were obtained.
