Gaussian smoothing kernel applied to image (0 == no filter).

Used when sampling bits. Filtering is a good idea in cases where A) a cheap camera is introducing artifical sharpening, B) the bayer pattern is creating artifcats, C) the sensor is very noisy and/or has hot/cold pixels. However, filtering makes it harder to decode very small tags. Reasonable values are 0, or [0.8, 1.5].

Gaussian smoothing kernel applied to image (0 == no filter).

Used when detecting the outline of the box. It is almost always useful to have some filtering, since the loss of small details won't hurt. Recommended value = 0.8. The case where sigma == segsigma has been optimized to avoid a redundant filter operation.
