The wrong statement about the key technologies of robot vision is()
A. The region-based segmentation algorithm has certain anti-interference ability to noise, and the selection of region characteristics is relatively simple
B. A method based on local feature invariants: it has excellent characteristics in describing local areas of the image and dealing with external noise
C. The detection of obstacles by binocular stereo vision technology is mainly based on the method of stereo vision
D. The performance of microwave radar ranging technology is relatively stable but the cost is high, and the space coverage area is limited, there may be some electromagnetic interference between each other

The application of computer vision in the measurement field includes angle measurement and length measurement.
The similarities between neural network and deep learning are ()
A. The system consists of input layer, hidden layer (multilayer) and output layer. Only the adjacent nodes are connected. Each layer can be regarded as a logistic regression model.
Both of them use BP algorithm to adjust the parameters, that is, using iterative algorithm to train the whole network.
C. During the training, the initial value is set randomly, the output of the current network is calculated, and then the parameters of the previous layers are changed according to the difference between the current output and the real label of the sample until convergence.
D. For a deep network (more than 7 layers), there will be gradient diffusion.
() does not belong to the field of digital image processing
A. Industrial testing
B. Physical discovery
C. Biomedicine
D. Identification of biological characteristics
In the following options, the three points that do not belong to the state space method are ()
A. State
B. Operator
C. State space method
D. Nodes and arcs or chains
