Research of Filtering Image Linear Characteristic Recognition Method Based on Improved Hough Transform

摘要

The analysis of the pixel response of the filtered image was the key to solve the problem of target recognition. A kind of method was proposed in this paper which the line characteristic extraction based on pixel window, and the rules of the line characteristic extraction were formulated. The traditional Hough transform was improved and then the characteristic extraction was performed. The computational complexity was reduced and the ability of the straight line to be recognized was improved by this way. The result showed that this method could extract the straight line target from the image of the filter response pixel through the simulation.
