Public Methods

Segmentation (const VolumetricData *map, bool cuda=true)

Creates a segmentation object given a 3D float array and volumetric metadata. Optional argument to disable CUDA. More...

Segmentation (float *data, molfile_volumetric_t *metatdata, bool cuda=true)

Creates a segmentation object given a 3D float array and volumetric metadata. Optional argument to disable CUDA. More...

Segmentation (unsigned short *data, molfile_volumetric_t *metatdata, bool cuda=true)

Segmentation (unsigned char *data, molfile_volumetric_t *metatdata, bool cuda=true)

~Segmentation ()

double segment (int num_final_groups, float watershed_blur_sigma, float blur_initial_sigma, float blur_multiple, MERGE_POLICY policy, const bool verbose=true)

Runs the segmentation algorithm until there are <= num_final_groups. More...

template<typename OUT_T> void get_results (OUT_T *results)

Copies the segmentation into the provided results array. Can be of type int, short, or (legacy) float. More...

unsigned long get_num_groups ()

Returns the number of groups in the segmentation. More...
