Detailed Description

template<class InputStorageType, class OutputStorageType>
class BIAS::DensityFilter< InputStorageType, OutputStorageType >

Removes areas from an image that have a low density (fill rate).

The primary focus for this class is filtering depth maps. For each pixel, it is determined how many valid neighbours it has. If this number is below a certain threshold, it is removed. Borders are completely ignored.

Member Enumeration Documentation

template<class InputStorageType, class OutputStorageType>
enum BIAS::FilterBase::TBorderHandling
inherited

enum for border calculation, same meanings as in matlab:

  • TBH_valid: returns only the pixels whose values can be computed without using zero padding of the input image. The resulting output image is smaller than the input image. The ROI of the output image is set accordingly.
  • TBH_same: returns the set of pixels that can be computed by applying the filter to all pixels that are actually part of the input image. Border pixels are computed using zero padding, but the center pixel of the computational kernel is applied only to pixels in the image. This results in an output image that is the same size as the input image.
  • TBH_full: returns the full convolution. This means conv2 returns all pixels for which any of the pixels in the computational molecule overlap pixels in the image, even when the center pixel is outside the input image. The resulting output image is larger than the input image. This is not implemented at the moment.
