The stroke segmentation is one of the important factors for checking recognition rate of online freehand sketching that is an effective way for expressing, communicating and recording ideas during conceptual design. Strokes are divided into convex and concave stroke depending on whether is change the vector direction of preprocessing points. The paper proposes two kinds of segmentation methods for...
Due to the characteristic of the blood flow in capillaries, the color distribution of the Micro-vascular image is uneven and its gray scale continuity is poor. At the same time, Micro-vascular image also has the characteristic that light color, low contrast with background and so on. Therefore we put forward a Micro-vascular image segmentation method based on the improved adaptive region growing....
In this note, the problem of stability for linear systems with interval time-varying delays is investigated. New Lyapunov-Krasovskii functionals (LKFs) are constructed which contain more information of delay and some triple-integral terms. By combining Jensen's integral inequality with delay decomposition technique and convex combination approach, the upper bound of the derivative of the Lyapunov...
This paper presents a method that groups multiple over traced pen strokes for converting online multiple over tracing sketches into line drawings. Firstly, tolerance zones around strokes are built during stroke preprocessing. Secondly, users inputs are divided into stroke groups by a grouping procedure, which relies on a over tracing judgment algorithom that uses the percentage of the sampling points...
Multiphase level set model is sensitive to initial contour curve and has huge computation in the process of the multiple objects' segmentation. This paper presents a novel Image segmentation method for multiphase scenario, which initialize the multiphase level set function by coarse image segmentation using fuzzy C-means clustering algorithm and apply graph cut algorithm to acquire multiphase output...
In this paper we propose a framework of a virtual clothing shop which meets the mass customization based on virtual garment design model. To incorporate the respective merits both online and custom-tailoring shops, the framework will be used to establish a new interactive model which consists of virtual human, virtual clothing and virtual interaction. Among this model, virtual interaction plays a...
This paper proposes a novel method using geometric-based classifiers, to recognize stroke as geometric primitives and develops a human-computer interface prototype system (FSR) for assisting designers during conceptual design stages, which make system interface easy and friendly to use. The system is designed to infer designers' intention and recognizes the input single strokes into more 2D geometric...
This paper presents a novel method for interpreting overtraced strokes to single line drawing. The approach consists of three stages: preprocessing, stroke classification, strokes grouping and fitting. The preprocessing methods include stroke preprocessing and grouping preprocessing. The former discuss the polygonal approximation to represents the stroke and the latter proposes a method to evaluate...
In the Internet era, the network becomes a sword fighting corruption. The prominent characteristic of networks such as open, virtual, efficient emerge in the field of fight against corruption. However, as a new thing, Network Anti-corruption faces many difficulties. This paper attempts to analyze and discuss the current status, problems and future about network anti-corruption.
