• Supports setting the probability threshold of the video analysis category. For example, when the probability threshold is set to 0.6, the detection result does not retain the detection result with probability ≤0.6.
• Supports setting the IOU threshold for video analysis results. If the IOU of the detection results is greater than the threshold, it means that the identified object is the same, and only one detection result is retained; if the IOU is less than the threshold, it means that different objects are detected, and multiple detection results are retained.
• Adds the function of releasing the detection process. After opening multiple video windows and enabling the detection for every window, when you close the windows, there still are multiple detection processes, occupying the video memory. When performing the video detection again, the application will release all idle detection processes, otherwise the detection performance may be affected.
