In this way, image brightness will be taken into account and the image edge should be simultaneously maintained as possible during filtering image noise.

这样，滤波时就可以考虑到图像的亮度信息，在滤除图像噪声的同时尽量保持了图像的边缘。

A small noise, power, brightness in the control of the low-loss high efficiency.

具有噪音小，功率大，在亮度控制范围内高效率低损耗。

This paper presents an idea for the average brightness temperature of antenna aperture and its expression for a lossless antenna with matched and unmatched noise sources.

本文提出了天线口面平均亮度的概念，给出了天线终端接有匹配噪声源和非匹配噪声源时天线口面平均亮温度的表达式。

Researchers further claim to have automatic noise reduction that safeguards detail through bilateral filtering, an established technique that uses brightness detection to avoid blurring edges.
