查询词典 segmentation

The algorithm is designed to work directly on the wavelet compressed domain which possesses the following characters: First of all, the multi-level gradient energy presentation of face pattern is proposed, which not only can highlight the facial parts in possible face patterns, but also can address effectively the problem of unknown size in face detection in compressed domain and therefore avoid the complex resolution transform in arbitrary ratios ; secondly, the skin-color model in YCbCr space is ameliorated to improve the reliability of skin segmentation; finally, a hierarchical detector which integrates the simply rule-based classifiers and complex neural network based classifier is designed to further improve the processing speed.

Aiming at the attributes of the high speed of cigarette package moving and strong noise in the field environment, the thesis carries out a dynamic imaging mode of random outer trigger and obtains the cigarette package images with high quality and high precision. The median filtering, image segmentation and other techniques of image pre-processing are applied to the character images, and the techniques of pattern recognition are employed to recognize the characters. The thesis optimizes and improves the recognition algorithm to satisfy the requirements of high speed real-time processing system. The whole system can online inspect and take statistics the print quality of the forgery-proof symbols on the outer packing of cigarette, achieving good results.
