Abstract

A method and apparatus for partitioning an object from an image, such that substantially the entire object is contained in the partitioned region, includes pre-setting a reference width for the object; extracting a shadow underneath the object from the image and determining a candidate region containing the object in the image based on the extracted shadow underneath an object in the image; acquiring an imaging width of the reference width at the location of the extracted shadow underneath the object in the image, and adjusting the candidate region based on the imaging width of the reference width such that the adjusted candidate region substantially completely contains the object; and partitioning the adjusted candidate region as a region containing the object from the image.
