Title:
BORDER REGION PROCESSING IN IMAGES
Document Type and Number:
WIPO Patent Application WO2008091207
Kind Code:
A8
Abstract:
A border region (70) is identified in an image (40) by calculating an average of pixel values in a row (20) or column (10) of the image (40). Differences in property values are determined between each pixel (30) in the row (20) or column (10) and a neighboring pixel (30) present on a same column (10) or row (20) but in a neighboring row (20) or column (10). An average difference is calculated based on these differences. The pixels (30) in the row (20) or column (10) are classified as belonging to a border region (70) or internal region (75) of the image (40) based on the average pixel value and the average pixel difference.
