Image file container

Abstract: An image container file has at least first and second multimedia streams (MSs). The first MS includes first image data representing an image. The second MS includes arbitrary data, which can for example, correspond to: a different representation of the same image; annotations to the first image data; second image data that together with the first image data form a new image with greater dynamic range, resolution, field of view or other attributes that can be derived from processing two or more independent images; or an executable file related to the first MS. The image container file can also include an extensible metadata to hold information describing one or more multimedia streams of the image container file. Further, the image container file may include DRM information to provide information related to obtaining a license to access encrypted data or verifying the authenticity of encrypted or unencrypted data.

Method for creating and using affective information in a digital imaging system

Abstract: An image file for storing a still digital image and metadata related to the still digital image, the image file including digital image data representing the still digital image, and metadata that categorizes the still digital image as an important digital image, wherein the categorization uses a range of levels and the range of levels includes at least three different integer values.

System and method for permitting a software routine having restricted local access to utilize remote resources to generate locally usable data structure

Abstract: A Java applet program loaded initially from a remote server is configured to receive additional user annotations for data displayed in an already opened applet window located at the user's client system. To increase the usefulness and flexibility of such program, the user is permitted to preserve/capture, during an interactive session, the modified applet window containing any such input or modifications to the applet window data. Because the updated applet window data cannot be written to the user's client system, however, (due to security restrictions), the present invention instead causes such modified window data to be converted to a standard compressed graphics file format (such as GIF for an image file for example), and then uploaded to the remote server. From there the applet can then open another applet window within a browser program pointing to the location of such file on the remote server. At that point, the user can then perform any desired operation on the file (i.e., such as printing or saving to a local file system) since the browser has access to the local system resources.

Lossless embedding of data in digital objects

Abstract: Current methods of embedding hidden data in an image inevitably distort the original image by noise. This distortion cannot generally be removed completely because of quantization, bit-replacement, or truncation at the grayscales 0 and 255. The distortion, though often small, may make the original image unacceptable for medical applications, or for military and law enforcement applications where an image must be inspected under unusual viewing conditions (e.g., after filtering or extreme zoom). The present invention provides high-capacity embedding of data that is lossless (or distortion-free) because, after embedded information is extracted from a cover image, we revert to an exact copy of the original image before the embedding took place. This new technique is a powerful tool for a variety of tasks, including lossless robust watermarking, lossless authentication with fragile watermarks, and steganalysis. The technique is applicable to raw, uncompressed formats (e.g., BMP, PCX, PGM, RAS, etc.), lossy image formats (JPEG, JPEG2000, wavelet), and palette formats (GIF, PNG).
