Patent number: 7406215Abstract: The invention provides methods of determining a correction for a misalignment between at least two images in a sequence of images due at least in part to sample movement. The methods are applied, for example, in the processing and analysis of a sequence of images of biological tissue in a diagnostic procedure. The invention also provides methods of validating the correction for a misalignment between at least two images in a sequence of images of a sample. The methods may be applied in deciding whether a correction for misalignment accurately accounts for sample motion.Type: GrantFiled: December 4, 2006Date of Patent: July 29, 2008Inventors: Thomas Clune, Philippe Schmid, Chunsheng Jiang

Patent number: 7260248Abstract: The invention provides methods of relating a plurality of images based on measures of similarity. The methods of the invention are useful in the segmentation of a sequence of colposcopic images of tissue, for example. The methods may be applied in the determination of tissue characteristics in acetowhitening testing of cervical tissue, for example.Type: GrantFiled: March 15, 2002Date of Patent: August 21, 2007Assignee: MediSpectra, Inc.Inventors: Howard Kaufman, Philippe Schmid

Patent number: 7003039Abstract: 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.Type: GrantFiled: July 18, 2001Date of Patent: February 21, 2006Inventors: Avideh Zakhor, Philippe Schmid

Patent number: 6902935Abstract: The invention provides methods and systems for monitoring effects of chemical agents on optical signals produced by samples in response to the chemical agents. Preferred methods comprise application of multiple chemical agents that interact to alter an optical signal from the sample. Methods and systems of the invention also comprise monitoring an optical signal from an endogenous chromophore upon application of a chemical agent to a sample. Methods and systems of the invention also comprise the use of triggers, atomizers and image alignment to enhance the results of methods described herein.Type: GrantFiled: December 15, 2000Date of Patent: June 7, 2005Assignee: MediSpectra, Inc.Inventors: Howard Kaufman, Alex Zelenchuk, Ross Flewelling, Philippe Schmid, Ze'ev Hed
