WebbPaper [] describes an Automatic Vehicle Classifier (AVC) for toll roads, based on video classification and installed on most of Russian toll roads. Vehicle Passage Detector (VPD) is one of the most important parts of the AVC system. VPD uses as input several binary signals from other AVC subsystems (binary detectors), and makes decisions about a … WebbThree classification models were tested: a 1-D convolutional neural network (CNN); a recurrent neural network (RNN); and a Bayesian neural network (BNN) based on the CNN architecture. The CNN model is … crystal for business growth
