Method of increase sharpness in digital displays |
摘要 |
A method for processing video data for increased sharpness. The data undergoes a process by which it is filtered in two dimensions. Using separable, one-dimensional filters, the process cores the data to prevent noise enhancement and applies gain to the resulting data. Finally, both dimensional filtered components are then combined to form the final sharpened image. Because of the separable nature of the process and filters, either one of the dimensional filters could be eliminated, while retaining the robustness of the method.
