Title:
ガイデットフィルタベースのディテール強調
Document Type and Number:
Japanese Patent JP6587317
Kind Code:
B2
Abstract:
Systems and methods for generating a detail-enhanced video signal are provided. In a method for generating the detail-enhanced video signal, an input video signal is received. A first signal that is a linear transformation of the input video signal is generated. A detail signal is generated by determining a difference between the input video signal and the first signal, where the detail signal includes information that is added to the input video signal to generate the detail-enhanced video signal. A filtered detail signal is generated by removing noise from the detail signal. The filtered detail signal is multiplied by a gain function to generate a second signal. The gain function is based on an amount of variance in the input video signal. The input video signal and the second signal are combined to generate the detail-enhanced video signal.
