The traditional k-means algorithm has sensitivity to the initial start center. To solve this problem, this paper proposed a new method to find the initial center and improve the sensitivity to the initial centers of k-means algorithm. The algorithm first computes the density of the area where the data object belongs to; then it finds k data objects, which are belong to high density area, as the initial...
A diagnosis system for pests on fruit trees based on multiple levels imprecise reasoning arithmetic is developed using Visual C++. Object-oriented knowledge expression method is used, which makes it easy to dig and express knowledge and make it efficiently to reason. The mixture of forward and backward reasoning mechanism is used in the system. The rule of depth preference is adopted when searching...
Contactless biometrics provide high comfort and hygiene in person recognition. Because of this, such systems are better accepted by the general public. This paper proposes an adaptive, contactless, biometric system which combines two modalities: palmprint and face. The processing chain has been designed to overcome embedded system constraints and small sample set problem: after a palmprint is extracted...
