8-9 | maxAccel8 | Maximum target acceleration (256*pixels/frame2) (-1 = not set) (not used in vehicle, person, drone, anomaly, radiometric, blob, maritime or gas mode) | ||||||||||||
10-11 | minWide | Minimum target width (pixels) (-1 = not set) (not used in vehicle, person, drone or gas modes) | ||||||||||||
12-13 | maxWide | Maximum target width (pixels) (-1 = not set) (not used in vehicle, person, drone or gas modes) | ||||||||||||
14-15 | minHigh | Minimum target height (pixels) (-1 = not set) (not used in vehicle, person, drone or gas modes) | ||||||||||||
16-17 | maxHigh | Maximum target height (pixels) (-1 = not set) (not used in vehicle, person, drone or gas modes) | ||||||||||||
18 | hideOverlapTrks | 1 = Hide targets that overlap with object tracks – these will not be displayed or reported in telemetry; 0 = Don't hide (not used in vehicle, person, drone, anomaly, or gas mode) | ||||||||||||
19 | nFramesBack | Number of frames to go back in time to compare frames in MTI difference mode, default 15. Parameter only applies to aerial and gas modes. Aerial: (5 to 15) Use 15 for small slow moving object detection and smaller numbers for faster larger objects. Gas: (2 to 15) Use 5 for a moving camera. Increase for fixed camera for more sensitivity or decrease for less enhancement. | ||||||||||||
20 | mergeRadius | Maximum distance between targets at which they can be merged into a single target (0 to 255 pixels), 0 = automatic, default = 0, typical is 10 to 25 (not used in vehicle, person, drone, anomaly, radiometric, blob, maritime or gas mode) | ||||||||||||
21 | mergeDirTol | Maximum angle heading difference between targets at which they can be merged (0 to 180 degrees), default = 45 degrees (not used in vehicle, person, drone, anomaly, radiometric, blob, maritime or gas mode) | ||||||||||||
22 | useRegistration | Use registration information to track detections from frame to frame (not used in vehicle, person, drone, aerial, staring or gas mode) | ||||||||||||
23 | detUpdateRate | Rate we update the background model for detection algorithms, 0-255. Larger values put more emphasis to the current frame. (not used in vehicle, person, drone, aerial, radiometric, blob, staring or gas mode) | ||||||||||||
24 | surroundSize | Blob Detection: size of surround for high pass processing default = 7. Range = 7-79 (odd numbers) (applies only to blob mode) | ||||||||||||
25 | reserved3 | Reserved | ||||||||||||
26-27 | bgTimeConst | Time constant (in frames) at which frames are averaged into the background model (at the default value of 600, the background will mostly be replaced after about 20 seconds (applies only to staring mode) | ||||||||||||
28 | bgEdgePenalty6 | Penalty to apply to edges in background model mode – typical values are 0 (no edge penalty) to 64 (full edge penalty), default 64 (applies only to staring mode) | ||||||||||||
29 | bgResetConf | Reset background model if registration confidence falls below this value; 0 to 100, default 40 | ||||||||||||
30 | bgResetOff | Reset background model if the registration column or row offset exceeds this value; 0 to 255, default 100 | ||||||||||||
31 | bgResetAng | Reset background model if the registration angle in degrees exceeds this value; 0 to 180, default 1 | ||||||||||||
32 | bgResetFrames | Reserved Allows for recovery from temporary bad frames or temporary large motion, but resets when there is a large amount of motion. | ||||||||||||
33 | bgWarpConf | Warp the background model if registration confidence falls below this value; 0 to 100, default 85 (applies only to staring mode) | ||||||||||||
34 | bgWarpOff | Warp the background model if the registration column or row offset exceeds this value; 0 to 255, default 32 (applies only to staring mode) | ||||||||||||
35 | bgWarpAng | Warp the background model if the registration angle in degrees exceeds this value; 0 to 180, default 1 (applies only to staring mode) | ||||||||||||
36 | bgWarpFrames | Reserved Allows for ignoring a small number of bad frames or temporary large motion, but warps when there is a significant amount of motion. | ||||||||||||
37 | maxTrackFrames | Number of frames to keep tracking once target has disappeared, 1 to 254; 0 = automatic, 255 = don't drop (not used in vehicle, person, or drone modes) | ||||||||||||
38 | debugFiltering | Debug flags to help user understand filtering based on size,velocity, and acceleration.
| ||||||||||||
39 | downsample | 0 = none 1 = 2x2 2 = 4x4 3 = 8x8 255 = automatic based on frame size (not used in anomaly mode). Note: Hardware limitations exist based on the platform and algorithm. | ||||||||||||
40 | maxTelemTrks | Maximum number of MTI tracks reported in SLATrackingPositions_t, default 10. If the total number of tracks is greater than maxTelemTrks, then the reported tracks are chosen based on which tracks have the highest confidence. | ||||||||||||
41 | maxKlvTrks | Maximum number of MTI tracks reported in the KLV data, default 10. If the total number of tracks is greater than maxKlvTrks, then the reported tracks are chosen based on which tracks have the highest confidence. | ||||||||||||
