Abstract
An image processing method includes estimating corners of a contour of an object area in an obtained image, searching for contour lines of the object area between every two points which are offset from the estimated corners within a predetermined degree or distance along a direction away from the object area respectively, and determining intersection points of the contour lines as final corners of the contour of the object area, and determining contour lines between the final corners as a final contour of the object area.
