The Affine Transforms for Image Enhancement in the Context of Logarithmic Models
Vasile Pătrașcu, Vasile V. Buzuloiu · arXiv (Cornell University) · 2014
The logarithmic model offers new tools for image processing. An efficient method for image enhancement is to use an affine transformation with the logarithmic operations: addition and scalar multiplication. We define some criteria for automatically determining the parameters of the processing and this is done via mean and variance computed by logarithmic operations.
