Remote-sensing technology has special advantages in estimating forest carbon storage and biomass on the ground. The paper summarizes three main methods of estimating forest carbon storage by using remote-sensing technology, namely, multielement regression analytical method, artificial neural network method and mathematical modeling method. Also the advantages and disadvantages of each method are explained...
Due to the inherent limitations of structure and dimensional, it is difficult to measure the surface roughness of micro-heterogeneous surface in deep hole. In this paper, the microscopic image of micro-heterogeneous surface is obtained by the long working distance lenses of digital microscopic camera, firstly. Thereafter, two artificial neural network models, which take microscopic image features...
Fingerprint classification is an important indexing method for any large scale fingerprint recognition system or database as a method for reducing the number of fingerprints that need to be searched. Fingerprints are generally classified into broad categories based on global features. This paper describes a new fingerprint classification algorithm that uses some curve features of ridgelines. The algorithm...
