A faster processrng speed and few saving space method of linear feature extraction method is proposed. Moreover, a one-pixel-wide image is represented as the result of this method . For approach this objective, I design a 8*8 block of the image data as a linear unit. Besides, I design a linear model which include 90s line model to fit the original image data, then create a new data structure file to save the information of the result, the space of the new data file is 1132 of the original image data file. In the post-processing, I develop a new link algorithm to link two linear units which have the same direction. That is to say the link method is able to link 8 pixels between two linear unit.
