Keep contours near ROIs

Description

Keep big contours inside a series of ROIs.
Small contours inside ROIs may be added on conditions.
Contours outside ROIs may be added to root contours if close enough Real time: False

Usage

• Mask cleanup: Cleans a coarse mask generated by threshold tools

Parameters

• Activate tool (enabled): Toggle whether or not tool is active (default: 1)
• Name of ROI to be used (roi_names): Operation will only be applied inside of ROI (default: )
• ROI selection mode (roi_selection_mode): (default: all_linked)
• Maximum distance to ROI (init_max_distance): Maximum distance to add a contour on initialization phase. If distance is >0, ROIs will dilated with a kernel of size distance. (default: 0)
• Minimum contour size (init_min_size): Minimum accepted size for a contour on initialization phase (default: 100)
• Delete all contours smaller than (delete_all_bellow): All contours below this size will be permanently ignored. The more smaller contours are delete, the faster the algorithm (default: 0)
• Merge distance for root contours (root_merge_distance): (default: 100)
• Aggregate small contours inside ROIs distance (small_contours_distance_tolerance): Aggregate small contours inside ROIs if closer than x to any root contour. Any aggregated contour is considered as a root one. (default: 100)
• Aggregate unknown contours distance (unk_contours_distance_tolerance): Aggregate unknown contours if closer than x to any root contour. Any aggregated contour is considered as a root one. (default: 100)
