Analysis on the patch characteristics of vegetation landscape of Daiyunshan nature reserve in Fujian;

Based on the analysis method with the indexes of landscape pattern,this paper analyzes the patch characteristics and the degree of landscape fragmentation of woodland landscape types in Fuzhou city from four respects: the general characteristics of landscape pattern,the size characteristics of pat.

In order to provide theoretic basis for conservation of the Wuyishan Scenery District,the landscape pattern and fragmentation were preliminary analyzed based on patch characteristics of landscape elements there.

On this basis,we had analyzed the community type,distribution pattern and patch character of Haloxylon desert vegetation.

This method introduces a subpixel technique and adopts the barycenter algorithm to compute the barycenter of characteristic speckle, which can avoid the complex process of computing the correlation coefficient in digital speckle method; experimental distortion curve for the measured object can be obtained through the related formulas of displacement.

This paper presents a new method that when you input a face image, it implements the image s gray; binary and filter respectively ,and then implements its facial expression recognition automated based on the feature of black speck arithmetic .
