Description
|
|---|---|---|
| dest | Image* | The destination image that will contain only the filtered particles. |
| source | Image* | The image containing the particles to filter. |
| criteria | const ParticleFilterCriteria2* | An array of criteria to apply to the particles in the source image. This array cannot be NULL. |
| criteriaCount | int | The number of elements in the criteria array. |
| options | const ParticleFilterOptions* | Options used by imaqParticleFilter to filter binary particles. |
| roi | const ROI* | The ROI whose contours a particle must be contained in to avoid being filtered out. If rejectBorder is true in options, any particle touching the border of a contour in roi will also be filtered out. Set this parameter to NULL to filter particles in the entire image based on the criteria array. |
| numParticles | int* | On return, the number of particles left in the image. |
