Steps to add new detector / tracker / ReID Algorithm

Select a unique algorithm name and enter into the following key in config.ini

For detector or tracker algorithm

det_algorithm=<NEW_ALGORITHM>

For ReID algorithm

reid_algorithm=<NEW_ALGORITHM>

Below the [General] section in config.ini, add a new section for the new algorithm. The name of the new section must match the new algorithm name.

[General]
...
...

[<NEW_ALGORITHM>]
...
...

Under the newly created section, enter variables required to instantiate or for options for the new algorithm.

[<NEW_ALGORITHM>]
variable1=<OPTION1>
variable2=<OPTION2>

Create a wrapper class for the new algorithm and place them in their dedicated folders.

For detector or tracker algorithm, create a new folder for the new algorithm under the Detector_Tracker folder and place all relevant files/models/weights/etc inside.
For ReID algorithm, create a new folder for the new algorithm under the ReID folder and place all relevant files/models/weights/etc inside/

Open Algorithm_Factory.py and import the wrapper class for the new algorithm.
Add code to instantiate the new algorithm in their respective algorithm methods.

For detector or tracker algorithm

def Detector_Tracker_Factory(config):
    detector = None
    algo = config['det_algorithm']
    ...
    ...
    if algo = '<NEW_ALGORITHM>':
        detector = NEW_ALGORITHM(
            ...
        )
    return detector

For ReID algorithm

def ReID_Factory(config):
    reid = None
    algo = config['reid_algorithm']
    ...
    ...
    if algo = '<NEW_ALGORITHM>':
        reid = NEW_ALGORITHM(
            ...
        )
    return reid

[For ReID Algorithm only] Open MultiVideoProcessor.py and go to method _reid_process_factory(self, reid). Add a new entry to the factory dictory key and assign the value to a new function for processing ReID feature extraction and scoring (refer to _processPersonReid method for example)

def _reid_process_factory(self, reid):
    factory = {
        '<NEW_ALGORITHM>': <NEW_ALGO_PROCESS_REID_METHOD>
    }
    return factory[reid]
