Two-dimensional digital transient improvement

摘要

A method can include receiving an input signal that includes an input image having an original edge, applying multiple one-dimensional (1D) Digital Transient Improvement (DTi) algorithms to the input image, summing each result of the application of each of the 1D DTi algorithms to the input image, and providing an output signal that includes an output image having an enhanced edge that results from the applying and summing and corresponds to the original edge.

1. A method, comprising:
receiving an input signal that includes an input image having an original edge therein; applying a plurality of one-dimensional (1D) Digital Transient Improvement (DTi) algorithms to the input image, wherein the plurality of 1D DTi algorithms includes a horizontal DTi algorithm and a vertical DTi algorithm; determining a delta value corresponding to the horizontal DTi algorithm; determining a delta value corresponding to the vertical DTi algorithm; summing each result of the application of each of the plurality of 1D DTi algorithms to the input image, wherein the summing includes performing a first adjustment based on the delta value corresponding to the horizontal DTi algorithm and the delta value corresponding to the vertical DTi algorithm; and providing an output signal that includes an output image having an enhanced edge that results from the applying and summing and corresponds to the original edge.
