摘要: A method ( 200 ) is disclosed of detecting one or more patterns embedded in an image. Each pattern the image has been formed from a one-dimensional basis function. The starts by calculating 210 projective transform 1-D correlation then calculated 220 between and function for selection angles. Finally, peaks are found 230 ). position each provides spatial parameters patterns.
