The second type of waveguide was formed in a …

A Heuristical Method Of Corner Points Detection On An Image Boundary, Qiulin Li

Theses

A heuristics-based method of corner points detection on an image boundary is proposed and implemented. The method uses the sampled boundary distances to find all of the candidate corner points along the image boundary. Then the curvature characteristical value is used to measure the severity of curvature change of the candidate points. Those candidates whose curvature characteristical value is under some threshold are eliminated. The paper also proposed some mechanism to reduce the effect of noises on the boundary. Experiments show that it is an efficient method and it gives satisfactory results on some image boundaries.

An Investigation Of Inking Adjustments Versus Their Response Time In A Web Offset Press, Shiuh-Dong Chung

Theses

This study discusses the response time of different inking changes. In press control, when the pressman notices a color variation on the press sheet, he/she needs to adjust the ink keys to bring the color back to the color on the OK sheet . The change of the ink level needs a particular time interval to reach a new equilibrium. When a process reaches a new press equilibrium, it reflects the ink change factor. This study investigates the time interval by applying two amounts of inking change and two kinds of measurement by X-Bar R chart analysis. The response times …

Context Sensitive Optical Character Recognition Using Neural Networks And Hidden Markov Models, Steven C. Elliott

Theses

This thesis investigates a method for using contextual information in text recognition. This is based on the premise that, while reading, humans recognize words with missing or garbled characters by examining the surrounding characters and then selecting the appropriate character. The correct character is chosen based on an inherent knowledge of the language and spelling techniques. We can then model this statistically. The approach taken by this Thesis is to combine feature extraction techniques, Neural Networks and Hidden Markov Modeling. This method of character recognition involves a three step process: pixel image preprocessing, neural network classification and context interpretation. Pixel …
