Class ExternPedestrianAttrRecognizer

java.lang.Object

org.cripac.isee.alg.pedestrian.attr.Recognizer

org.cripac.isee.alg.pedestrian.attr.ExternRecognizer

public class ExternPedestrianAttrRecognizer
extends PedestrianAttrRecognizer

The class ExternPedestrianAttrRecognizer is a recognizer of pedestrian attributes that depend on external solvers connected with sockets. It sends recognition requests each containing a track to the solver, then receives responses containing the attributes. The requests and responses are processed asynchronously, matched by request UUID. Request format

16 bytes - Request UUID.

4 bytes - Tracklet length (number of bounding boxes).

foreach bounding box: {

16 bytes - Bounding box data (x, y, width, height).

width * height * 3 bytes - Image data.

}

Response format

jsonLen bytes - Bytes of JSON string representing the attributes.
