The Method of Ostu Used in the Video Detection of Vehicles
The paper researches the threshold segmentation arithmetic of the video vehicle measurement. It is the images preprocessing that using the method of least square fitting to adjust the primal image and dealing the image with the median filter. For the threshold selection, the article gives the theory of the state method, 2-mode method, iterative method and Ostu method and analyses them to make the vehicle separating with the background. Through the dealing results, the state method is the most simple method, but it is easy effected by the researcher; The 2-mode method can be used in certain image and the result approved that this method is not fit for the video vehicle image; The iterative method has similar result as the Ostu method, but it has complex programming and need long time to process. So the Ostu method is selected to processing the video vehicle image in this project. Through test, the Ostu method can make the parameters of the vehicles extracted effectively.
