Abstract
Description
-
- 1. Picture details whose detection mainly depends on the level of noise in the image occupy approximately 50-80% of an image.
- 2. A visual perception detection threshold for image details does not depend on the shape of the details in the image.
- 3. A visual perception threshold THD depends on a number of picture parameters, including the general brightness of the image. It does not depend on the noise spectrum.
