Abstract
A method can include receiving an input image, performing an edge-preservation enhancement on the input image, performing a local-extrema enhancement on the input image, and performing a digital transient improvement (DTi) operation on the input image. A gradient-based fusion of an output of the edge-preserving enhancement and an output of the local-extrema enhancement may be performed, and a transient-based fusion of an output of the gradient-based fusion and an output of the DTi operation may also be performed.
