Image Data Processing Methods

Abstract

Provided are image data processing methods. Such methods include obtaining image data with at least one bar pattern, detecting coordinates of an edge of the bar pattern, extracting an outline curve of the bar pattern by fitting the coordinates of the edge, setting a direction of a major axis by differentiating the outline curve of the bar pattern, rotating the image data to match the major axis with a reference axis, and extracting information of the bar pattern by processing the bar pattern of the rotated image data.

Dependencies are inferred from the claim text.
