For a local enhancement using mean and variance, there is one condition: σs(x, y) ≤ k2DG, where, MDG is global standard deviation, k2 a positive constant and σs(x, y) a measure of contrast at point (x, y). Then, which fact is true for k2 if its values is less than 1.0?

Answer 1

For local enhancement using mean and variance, the condition is:

The size of the local window or neighborhood should be appropriately chosen so that it is large enough to provide reliable statistical measures but small enough to capture local features without smoothing out important details.

This ensures that the mean and variance values calculated within the region effectively represent the local characteristics of the image or data, enhancing local details without being influenced by larger-scale variations or noise.
