## Parameters

- [param] -psin <string> Ground truth vector data for positive samples. Mandatory: True. Default Value: ""
- [param] -nsin <string> Ground truth vector data for negative samples. Mandatory: True. Default Value: ""
- [param] -belsup <string> Dempster Shafer study hypothesis to compute belief. Mandatory: True. Default Value: ""
- [param] -plasup <string> Dempster Shafer study hypothesis to compute plausibility. Mandatory: True. Default Value: ""
- [param] -cri <string> Dempster Shafer criterion (by default (belief+plausibility)/2). Mandatory: False. Default Value: "((Belief + Plausibility)/2.)"
- [param] -wgt <float> Coefficient between 0 and 1 to promote undetection or false detections (default 0.5). Mandatory: False. Default Value: "0.5"
- [param] -initmod <string> Initialization model (xml file) to be used. If the xml initialization model is set, the descriptor list is not used (specified using the option -desclist). Mandatory: False. Default Value: ""
- [param] -desclist <string> List of the descriptors to be used in the model (must be specified to perform an automatic initialization). Mandatory: False. Default Value: ""
- [param] -maxnbit <int32> Maximum number of optimizer iteration (default 200). Mandatory: False. Default Value: "200"
