    摘要: A method for assessing the image quality of image data acquires image data, segments the image data into at least one spatial region, obtains a plurality of image quality measures for the at least one spatial region, and forms at least one quality vector that has two or more quality measures for the at least one spatial region. The at least one quality vector is classified into one of a plurality of predefined quality classes.

    摘要: A method for producing an assured image from image data that is transferred from a first entity to a second entity acquires image data, transfers the acquired image data from the first entity to the second entity, forms secure assurance data according to image quality measurements obtained from the acquired image data, and forms an assured image that includes the acquired image data and the secure assurance data. At least one image quality message is generated that indicates the transfer of the acquired image data from the first entity to the second entity and is representative of the image quality measurements. The at least one image quality message is presented to at least one of the first entity and the second entity.

    摘要: A method for embedding a watermark signal that contains message data in a digital image represented as a two-dimensional array of pixel values, includes the steps of: providing a dispersed message image having pixel values representative of the message data; modifying each pixel value of the dispersed message image as a function of the corresponding pixel value in the digital image; and combining the modified dispersed message image with the digital image to produce a watermarked image.
