Fingerprint classification is crucial to reduce the processing time in a large-scale database. In this paper a fingerprint classification based on continuous orientation field and singular points is proposed. The continuous orientation field can not only filter the noises in point directional image,but also represent the basic structural feature of(More)
To achieve higher education internationalization and cultivate the more new inter-disciplinary talents, it is necessary to implement bilingual teaching in computer speciality. How to further improve bilingual teaching and push the work to a higher level from its current situation is currently an important subject to be discussed in the reformation of(More)
Since first isolated from the lipophilic extract of Streptomyces sp. SF2583, streptochlorin, has attracted a lot of attention because of its various pharmacological properties, such as antibiotic, antiallergic, antitumor, and anti-inflammatory activities. For the efficient preparation of streptochlorin from a producing strain Streptomyces sp. SYYLWHS-1-4,(More)
This paper addresses the problem of reconstructing implicit surface from scatter point cloud with noises. We introduce a filtering operator based on improved trilateral filter, which can reduce noise effectively, while preserving sharp feature. The filtered data points are divided into subdomains using an adaptive octree subdivision method, and a local(More)
Segmentation is an important step in a fingerprint recognition system. Different methods have been proposed for fingerprint segmentation. In this paper, some of the most important segmentation methods are introduced and an improved adaptive threshold algorithm based on multiple features is introduced and implemented. Morphology technology is applied as post(More)
Data Structure is the core course in the computer specialty, which aims to cultivate undergraduates' abilities of selecting appropriate data structures to develop high quality application programs. CDIO teaching model has already become one of hotspots and effective solutions to improve teaching quality and teaching effect. By learning advanced CDIO model(More)
OBJECTIVE To investigate whether microvascular damage is involved in the pathogenesis of heroin induced spongiform leukoencephalopathy (HSLE). METHODS The brain tissues were collected from 4 HSLE patients and 5 controls and then fixed in 4% paraformaldehyde. The frontal lobe, corpus callosum and cerebellum were separated. The expressions of myelin base(More)
In order to meet the requirements from the enterprises and enhance employability of students of computer science. This paper gives the model for developing the innovative ability of applied computer undergraduates based on CDIO. Guiding by computer application professional demand, referencing to international advanced CDIO engineering education idea and(More)
