The graduation design is mainly to the rotation of the spot diagram of progressive study way， and will the results applied to the specific image The research content involves coordinate transform principle， image edge detection and computer geometry some of the Some figure rotation in image registration this field of vital Some figure rotation way including origin rotating， rotating central and arbitrary point Some figure origin of the principle of coordinate transformation of rotating use: first， to get what rotation matrix on the drawing， and then point every point coordinates times the matrix can get rotated point Some figure of the process of rotating central on original image is first the all point to the center of the coordinates minus again， finally the coordinate transformation will get all the point coordinates the Add center The spot diagram of an arbitrary point rotation method and the method of rotating central to the center of the same， but will coordinate change at any point In specific image rotation， rotated image will have some deformation， its reason says simple point is pixels integer and produced some blank To improve the quality of image rotation in spinning process of calculation and the interpolation point blank
Recruitment network in the tourism industry of thinking， as the communication and electronic products and the formation of the rapid development of network technology， the Internet more and more in-depth people's lives; recruitment network in the tourism business in human resources management is widely In this paper， the characteristics of network technology recruitment， development prospects and recruitment network in the tourism industry in the application of the situation and their strengths and deficiencies in the application areas were also discussed
