     this paper presents an approach for fast segmentation of foreign fiber images and precise recognition of foreign fiber objects using machine vision. live images were acquired in real time using a line scan ccd camera. after an image was acquired it was transferred to a host computer immediately for image processing and object classification. the captured image was firstly segmented according to the mean and standard deviation of r, g and b values of each pixel in the image. then noises were removed using the area threshold method. afterwards, color features, shape features and texture features of each foreign fiber object were extracted. finally, a one-against-one directed acyclic graph multi-class support vector machine (oao-dag msvm) was constructed and used to perform the classification. the results indicate that the image processing algorithm is fast and precise; the oao-dag msvm gets a mean accuracy of 92.34% and a mean classification time of 12 ms, which can satisfy the accuracy and speed requirement of online classification of foreign fibers.
