Changes:

Updated documentation;
Updated the «detailed_vehicle_emergency» classifier to «detailed_vehicle_emergency_v2», which worked faster while maintaining the accuracy of recognizing emergency services and the presence of a flashing light.

Changes:

Added the STREAM_FP_VEHICLE_TRACK_ALGO variable to select the area for human detect. Then if human detection matches with vehicle detection it is false positive vehicle detection (default: vehicleCrop);
Added GPU support for video stream processing, which sped up image processing. Now you can choose whether to process video streams on the GPU or CPU, depending on the configuration. This primarily improved the performance of the detectors.

Fixes:

Fixed a problem with stream creation when the license plate detector threshold was set to 1. Added validation for this threshold so that the stream was successfully created with the given value or an error was logged.

New features:

Added support for a new version of the classifier to determine whether a vehicle belongs to emergency services and whether it has flashing lights.

Changes:

Reworked the XLSX export structure: removed grouping, placed images first, and positioned textual information to the right of the images and license plate recognitions. Multiple values (plates, colors, countries) were now stored in a single cell separated by \n;
Added logic for automatic deletion of old records to prevent server memory overflow, improving aggregator stability. Implemented disk space checks before deleting data: if the percentage of free disk space is less than ANALYTICS_DISK_FREE_SPACE_THRESHOLD, the old data is deleted.

Fixes:

Fixed an issue where the stream continued processing a camera after it was turned off. Now, if the camera was disabled, the stream correctly stopped its processing and removed the camera.

Changes:

Optimized plugin build process by relocating them, which has eliminated dependence on artifacts and folder synchronization;
Updated Guardant in the package: installed Guardant version 3.29 to prevent issues.
