Abstract


Down is the poultry skin derivatives, in addition to meet their different flying ability to walk, play a role of weatherization. Down light, soft, warm \Down kind of identification are detected through the microscope with the naked eye, manual identification of feather samples. This identification requires a lot of training and practical experience, testing personnel must have a full understanding of goose, duck, feathers in the hair of terrestrial birds, pigeons, wool and other morphological characteristics of waterfowl hair. The detection process many human factors, may cause the same sample different test results. Moreover, if the manual identification for a long time, is easy to cause visual fatigue. Automatic test equipment must be developed to improve the objectivity and accuracy of identification. Domestic and foreign automatic test equipment is used to identify the down has not yet been reported. Geese, duck down microscopic structure on the basis of the research and analysis, we have developed based on the kind of support vector machine down automatic detection system. The main work of this paper is as follows: 1. Analysis and study of the microscopic structure of the feather, the judgment characteristics suitable for the computer to automatically detect. Down image of the image processing method, image smoothing, to increase the image contrast, and other image enhancement method the is down image method for an image pretreatment; as well as image segmentation technology research, with the best threshold value on down image threshold segmentation, get down testing requirements to meet the binary image. 3 discusses the theoretical knowledge of the SVM theory and mathematical morphology, and based on the kind of support vector machine down automatically detect new ideas. Conducted through the turbot section down image recognition, and identified Ling section pairing calculation pitch ultimately determine the kind of the feather goose, duck down or non-goose duck down. Proposed down type of automatic detection system of the overall program, and down type of automatic detection system software design. VC 6.0 under Windows 2000, development tools, and ultimately developed a user-friendly, easy-to-down type of automatic detection system software. Image processing, mathematical morphology, SVM theory and technology to achieve the kind of automatic detection down to overcome the many drawbacks of manual inspection, reducing the manual inspection may be wrong, feather types of detection methods a try and break ; research and development of the system, a substantial increase in the means of identification with the level of down, has broad prospects and promotion, and to fill the blank in this field at home and abroad.
