In the view of the fact that the information of the fault characteristic of the train wheelset is submerged into the background noises and the conventional spectral analysis method has its own deficiency due to the fuzzy spectrum value created by the load variation and rotation speed fluctuation, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from...
The image super-resolution and its reconstruction techniques are introduced, the super-resolution evaluation criterion is preliminarily discussed, the minimizing norm of image difference gradient modular square sum, frequency domain method and profile density curve method are proposed and simulation tests and analysis are carried out in this paper. It is shown from the tests that these methods are...
This paper discusses characters segmentation and characters recognition in intelligent license plate recognition system. According to the characteristics of the license plate, a projection method is used in characters segmentation. After the normalization processing of the characters image, a BP algorithm is applied into recognition of license plate
According to the optical image, the layered model for image degradation is established on the basis of imaging mechanism. Some key factors (diffraction effect and down-sample etc.) resulting in the low resolution are pointed out. A method of super-resolution image restoration based on separation is proposed and the algorithm of ally-template is introduced. This separation method reduces the complexity...
