Noise robust contrast-enhancement engine employing IIR filters

Abstract:

A noise robust contrast-enhancement engine utilizes low-pass infinite-impulse-response filters for enhancing the contrast while preventing noise amplification in video/image signals.

Abstract(Chinese):

噪声鲁棒的对比度增强引擎利用低通无限脉冲响应滤波器来增强对比度，同时防止视频/图像信号中的噪声放大。
