Detailed Description

Performs Exact Euclidean Distance Transform function using the Parallel Banding Algorithm (PBA+) defined by Tiow-Seng Tan, et al paper named "Parallel Banding Algorithm to Compute Exact Distance Transform with the GPU" published dated August 8, 2019.

Output for these functions is an optional 16-bit signed integer voronoi diagram (pairs of signed 16 bit integer x, y distance values) and/or an optional true euclidean distance transform image generated from the internal voronoi diagram in either unsigned 16-bit truncated integer format or 32-bit floating point format. Additional optional output can include an signed 16-bit integer Voronoi diagram containing site indices and/or a signed 16-bit integer Voronoi diagram containing relative Manhattan distances to the closest sites. Minimum and maximum image ROI widths and heights are 64 and 32767.

The nMinSiteValue and nMaxSiteValue parameters can be used to control which source image pixels are considered sites(traditionally 0) and non-sites (everything else).

Antialiased true distance transform, when available, is only available as double precision floating point (Npp64f) output data only and is enabled by setting the pAntialiasingDeviceBuffer pointer parameter to a non-NULL value.

The algorithm used for antialising is derived from the edtaa4 version from "Anti-aliased Euclidean distance transform" by Stefan Gustavson et. al. published in 2009 and is used under the permissions specified below.

Derived from edtaa4.c - compute the Euclidean distance transform of an image, with more accurate handling of 1 pixel wide anti-aliased edges.

This is a MEX-file for MATLAB. MATLAB is a product of The MathWorks, Inc.

Code in "edtaa4func.c" originally by Stefan Gustavson 1994, implemented from a verbal description in the PhD dissertation of Ingemar Ragnemalm, dept of EE, Linkoping University.

1 channel 32-bit floating point grayscale to optional 1 channel 16-bit signed integer euclidean distance voronoi diagram and 32-bit floating point transform with optional sub-pixel shifts.

For this particular version of the function acceptable input pixel intensities are less than or equal to 0.0f for those fully outside of connected pixel regions, intensities with fractional parts between 0.0f and 1.0f representing the percentage of connected pixel region sub-pixel coverage within a particular pixel (region contour), and intensities greater than or equal to 1.0f for pixels that are fully contained within closed connected pixel regions. This function executes in two passes, the first pass prioritizes pixels outside of closed regions, the second pass prioritizes pixels within closed regions. The two passes are then merged on output. The function assumes that fully covered pixels have centers located at sub-pixel locations of .5,.5 .

Parameters

pSrc	Source-Image Pointer.
nSrcStep	Source-Image Line Step.
nCutoffValue	source image pixel values < nCutoffValue will be considered fully outside of pixel regions (and set to -1).
