The upshot is a set of feature maps, one for each filter, showing which patches of the original image contain the sought-after element.

结果就获得了一套特征图谱，每个过滤器得到一套，每个特征图谱都显示了原初图像中的一小块，这一小块包含有该图像最显著的元素。

Next, the maps are swiped again, but this time rather than stopping at each pixel, the filter takes a snapshot every few pixels.

接下来，对图谱再次进行扫描，但这次过滤器会每隔若干像素就拍张快照，而不是每个像素都要挨个儿停留。

When the number of maps is low, you can use routing or filter nodes in the message flow, but this method becomes increasingly difficult as the number of maps used by the message flow increases.

当映射数量很少时，您可以在消息流中使用路由或过滤器，但是随着消息流所用映射数量的增加，使用这个方法的难度也在增加。

Also known as a Sobel filter. this generates normal maps that are sharper than Standard.

也称为索贝尔过滤。这会产生出比标准更清晰的法线贴图。

As shown in the following code snippet, the bright-pass filter first maps the scene to a desired middle gray target luminance before subtracting out the dark areas.

下面的代码片段展示了光亮过滤器在减去黑暗区域之前首先映射场景到希望的中等灰度的亮度的物体。
