Abstract: A method of detecting a barcode that in one embodiment includes performing a line segment detection of a barcode image to provide a plurality of line segments, and analyzing the line segments using parallel segment detection to determine a best candidate line segment having a greatest similarity to a remainder of adjacent line segments. The method may further include providing a central bisector of the best candidate line segment, and forming a plurality of parallel lines offset from the central bisector. In a following step, a pixel map is from the central bisector and the plurality of the parallel lines, and an end and a start of the barcode is determined from changes in intensity of the pixels in the pixel map.

Abstract: A method for barcode detection, barcode detection system and program. In method for detecting a barcode, an information processing apparatus executes the steps of: detecting a plurality of blobs from an image; for each detected blob, obtaining imaginary lines bisecting the detected blob perpendicular at the middle of the detected blob, determining at least one cluster of the imaginary lines in a feature space according to slopes and positions of the imaginary lines and grouping the blobs in one cluster to a rectangular shape corresponding to the barcode.
