tendrils for opencv based cells should follow the following rules.


In general, the name of opencv tendrils is determined by what they are as datatypes and not what they do.

  • image for any image, unless it must be further disambiguated, e.g. in the case of image, and depth, and may be of common image type.
  • mask for an image based binary mask, and be of type CV_8UC1. Generally this should be an optional input.
  • points for any collection of 2d or 3d points, and the should be an NxM multichannel matrix where the number of dimensions is apparent in number of channels.
  • R is a 3 by 3 rotation matrix
  • T is a 3 by 1 translation vector
  • K is a 3 by 3 camera intrinsic matrix
