ABSTRACT:
Certain embodiments of the invention may be found in a method and system for automatic aspect ratio detection and may comprise scanning lines in at least a selected portion of an image and locating a first reference pixel in one of the scanned lines. A corresponding sliding sum and a sliding number may be generated starting from the first reference pixel and a white edge determined based on the generated sliding sum and/or the generated sliding number. The first reference pixel may be a non-black pixel and a value which corresponds to and defines non-black may be variably defined. The sliding sum and the sliding number may utilize m bins, where m is greater than one (1). A luma sum threshold may be compared with the generated sliding sum to locate the white edge for aspect ratio detection.
