The Visitor counting parameters. The Administrator client
Parameters | A working name of a parameter | A parameter type | A default value | An acceptable range * | A parameter description |
|---|---|---|---|---|---|
Frames per second. | fps | float | 5.0 | [1, 30] | A certain number of frames per second a video is processed. |
Prediction confidence threshold | confidence_threshold | float | 0.5 | (0, 1) | Detection score threshold applied for predicted objects. |
Motion area expansion | motion_margin | float | 0.5 | (0, +inf) | Additional context which would be taken around the movement area before passing it into detector. Denotes size relative to motion rect size. Thus 0 means no margin, 1 is to extend motion area two times etc. |
Event processing time | aggregation_time | float | 1.0 | (0, +inf) | Time (in seconds) during which the best object snapshot is selected for recognition. Higher values increase the quality of recognition, but also increase the delay between object appearance and event geneation. |
Track lifetime without new events | track_lifetime | float | 5.0 | (0, +inf) | The lifetime of an object track in seconds. |
*In the Acceptable range column, square brackets “[” and/or “]” mean that the threshold values can be used as the default ones; parentheses “(” and/or “)” mean that the threshold values cannot be used as the default values.
