From this simple lowpass filter, the signal goes to the active tone control stage.

从这个简单的低通滤波器，信号到积极的基调控制阶段。

Tone mapping is performed in two places within the code: once in Render as part of the final shader pass to compose the glare textures onto the scene, and once as part of the bright-pass filter.

色调映射执行两处代码；一处是在渲染中作为最终着色器的一部分传给合成的耀光纹理到场景中，一处是作为光亮过滤器的一部分。

It is shown that the tone jamming rejection performance of the adaptive optimal filter scheme is superior to those of other two schemes, whichever precision is used.

双精度或单精度编程，其自适应最佳滤波器方案的单频干扰抑制性能，均优于其它两种方案。
