Method of determining orientation of image

摘要: In an image handling process in which a human body is recorded and processed reproduced, the position or orientation of image, such as normal erect lying 90° rotated position, automatically determined. The determination carried out by comparing distribution signal level vertical direction with thereof horizontal direction, based on difference pattern distributions. distributions determined use dispersion symmetry another aspect, characteristic values vertically extending strip area horizontally both passing through central are compared. As can be used total average level. Based between areas, whether not
