Abstract
Concerning the traditional sub-pixel edge detection techniques need to use the traditional edge detection algorithms for coarse positioning before precision positioning the algorithm of sub-pixel edge detection without rough localization was proposed.Concerning the edge information loss of color image principal axis analysis method was proposed to preserve the edge information.Concerning image edge feature gets blurred after filtering a median filter algorithm based on bisecting K-means was proposed.Bisecting K-means median filter algorithm can enhance the image edges when filtering out the noise.At the end by comparing the result at the aspects of detection accuracy,efficiency and reliability the validity of the algorithm proposed can be proved.
