Intelligent recognition of tobacco curing process based on wavelet kernel extreme learning machine
In order to solve the problems of large manpower consumption and unstable baking quality in the tobacco curing process,an intelligent recognition method of tobacco curing process based on wavelet kernel limit learning machine is proposed in this paper.In the experiment,the six baking stages including leaf softening,main vein softening,leaf curling,leaf small rolling,leaf large rolling and stem drying during the three-stage baking process were identified.The color,texture,temperature and humidity features were extracted from the six baking stages and a 9-dimensional feature vector was established to enter the wavelet kernel extreme learning machine.The number of neurons was adaptively selected through an incremental algorithm to identify the six stages quickly and accurately.The recognition rate was 98.33%.The experimental results show that the intelligent recognition method of tobacco curing process based on wavelet kernel extreme learning machine is feasible,which lays a theoretical foundation for the development of tobacco curing intelligent control system.
