Abstract: Systems and methods for determining an object location relative to a digital document are disclosed herein. A marking is applied to at least one cell in at least one row and to at least one cell in at least one column of a digital document. The markings define an axis system for the digital document. Each object has a stored digital address within the digital document. When the digital document is converted into a fixed file format, a location of the object can be determined that will match the location of the object on the printed page. By comparing the digital address of the object to the axis system defined by the markings, after the document has been converted to a fixed document format, the location of the object is defined spatially.

Abstract: This invention relates to the creation of dictionary functions for the encoding of video signals using matching pursuit compression techniques. After an initial set of reference dictionary images is chosen, training video sequences are selected, and motion residuals are calculated. High energy portions of the residual images are extracted and stored when they match selection criteria with the reference dictionary. An energy threshold is used to limit the number of video signal “atoms” encoded for each frame, thus avoiding the encoding of noise. A new dictionary is then synthesized from the stored portions of the image residuals and the original reference dictionary. The process can then be repeated using the synthesized dictionary as the new reference dictionary. This achieves low bit rate signals with a higher signal-to-noise ratio than have been previously achieved.
