Abstract:
1. A method for evaluation and stabilization over time of classification results from a classification method which proceeds in computer-assisted fashion, the method comprising: sensing, by sensors, objects to be classified over a period of time; repeatedly classifying the objects, by a computer processor, using specific quality parameters for each object class, wherein each classification utilizes a separate instance of sensor data obtained over the period of time by the sensors; increasing, by the processor, a value of a confidence parameter of an object class, the confidence parameter being calculated from the quality parameters and the increasing being conditional upon a subsequent one of the classifications confirming a result of a previous one of the classifications; decreasing, by the processor, the value of the confidence parameter of an object class, the decreasing being conditional upon a subsequent one of the classifications failing to confirm the result of a previous one of the classifications; and generating, by the processor, a final classification result including the confidence parameters that have been increased or decreased in value.
