This class inherits from `BaseSolution` and provides functionality to define polygonal regions in a video frame, track objects, and count those objects that pass through each defined region. Useful for applications requiring counting in specified areas, such as monitoring zones or segmented sections. Attributes: region_template (dict): Template for creating new counting regions with default attributes including name, polygon coordinates, and display colors. counting_regions (list): List storing all defined regions, where each entry is based on `region_template` and includes specific region settings like name, coordinates, and color. region_counts (dict): Dictionary storing the count of objects for each named region. Methods: add_region: Add a new counting region with specified attributes. process: Process video frames to count objects in each region. initialize_regions: Initialize zones to count the objects in each one. Zones could be multiple as well. Examples: Initialize a RegionCounter and add a counting region >>> counter = RegionCounter() >>> counter.add_region("Zone1", [(100, 100), (200, 100), (200, 200), (100, 200)], (255, 0, 0), (255, 255, 255)) >>> results = counter.process(frame) >>> print(f"Total tracks: {results.total_tracks}") c zt|di|dddddd|_i|_g|_|j y)zSInitialize the RegionCounter for real-time object counting in user-defined regions.zDefault RegionNrr r )rrr)namepolygoncounts region_color text_color)super__init__region_template region_countscounting_regionsinitialize_regions)selfkwargs __class__s f/var/www/pod-logistic/pod-ai/venv/lib/python3.12/site-packages/ultralytics/solutions/region_counter.pyrzRegionCounter.__init__(sJ "6"$+#    " !c|jj}|j||j|||d|jj ||S)a1Add a new region to the counting list based on the provided template with specific attributes.
