Abstract:
An image processing method includes acquiring an original image, acquiring original information, generating overlay information, determining where to embed the overlay information, evaluating whether the overlay information is embeddable in the original image, and controlling image processing according to a result of the evaluation. The image processing apparatus includes an image acquisition mechanism for acquiring an original image, an information acquisition mechanism for acquiring original information and generating overlay information, an embed position determination mechanism for determining where to embed a bit of the overlay information, an embed evaluation mechanism for evaluating whether the overlay information is embeddable in the original image, and an image processing control mechanism for controlling image processing according to a result of the evaluation. A computer readable storage medium storing a computer program product which causes the image processing apparatus to perform the image processing method.
