Research of Image Feature Information Card Based on Self-drawn Figure by User
Yong Dai · 2003
The paper descibes a new type of feature information card-images feature information card based on self-drawn figure by user (IIC). The paper constructs the mathematical models which are fit to the relation between geometric structure of dynamic sampling IIC installing structure of sensor; According to the method of vertical and horizontal inclining gradually, we take advantage of infrared double-diode to arrange IIC pattern information and make use of software and hardware to collect it alternately and dynamically; The paper constructs electric circuit models of sampling system of IIC; The paper proposes various effective algorithms to restore primitive double-value electronic image twisted for need of sampling to the original electronic image. At the same time, the sampling algorithm of IIC in combination with software and hardware reflect vivid features. IIC has some outstanding advantages, such as convenient application, cheap hardware cost, ingenious bulk, distinct and reliable result integrated software with hardware. Because of the advantage of self-drawn figure by user. IIC would have broad developing and applying prospect in lots of domains, such as door-lock, authority management, pattern recognition and its manipulation, etc.
