This paper concerns the problem of standing tree volume measurement based on digital image processing. A computer and a camera were used in our work. Before the tree photo was taken, two red color marking labels were attached on the trunk. After the marking points and the tree trunk were extracted, the tree trunk edges were fitted with a high order curve. Then the volume of tree trunk of any height selected with a rectangle can be calculated. The experimental results show that the relative measurement error is low enough. So it is a viable method.
Due to environmental changes and other reasons, the types of skin diseases continue to increase, the incidence rate and mortality rate are also rising, and the number of patients is increasing. In addition, people's care for the skin has increased, and the requirements for skin diagnosis and treatment have increased. There are few doctors and many patients, so it is difficult and troublesome to see a doctor. The diagnosis and treatment of skin diseases presents unprecedented challenges. In this paper, the WeChat applet of mobile terminals such as mobile phones is used as the front end to realize the collection, upload and display of information. The server end uses artificial intelligence technology such as convolutional neural network to realize the recognition of skin diseases, build an intelligent diagnosis and treatment system for skin diseases, and realize the diagnosis and scientific treatment suggestions for the patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
