Discrimination Level
Definition
Specifies a capacity to recognize a target of interest according to a given level of discrimination.
You can use video for identifying a wide range of detail, from motion detection to positive identification of a person for forensic evidence. Not every video system needs to be capable of performing positive identification. Select a video system that conforms to the requirements the application needs, without over- or under- specifying the system.
Use Characteristics
Consider: What level of discrimination do you need to recognize a target of interest?
Use Discrimination | Characteristic | Example |
---|---|---|
High-level description of actions that took place | General Elements of the Action | People or person present |
Large-scale recognition | Target Class Recognition | Car vs Van |
Medium-scale detail recognition | Target Characteristics | Gender, markings, smaller actions |
Enough detail to make a positive recognition | Target Positive ID | Face, object, alpha-numeric |
