Patent number: 11705117Abstract: Acoustic features are batched into two different batches. The second batch of the two batches is made in response to a detection of a word hypothesis output by a speech recognition network that received the first batch. The number of acoustic feature frames of the second batch is equal to a second batch size greater than the first batch size. The second batch is also to the speech recognition network for processing.Type: GrantFiled: October 13, 2021Date of Patent: July 18, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Hosam A. Khalil, Emilian Y. Stoimenov, Yifan Gong, Chaojun Liu, Christopher H. Basoglu, Amit K. Agarwal, Naveen Parihar, Sayan Pathak

Patent number: 9710730Abstract: Image registration is described. In an embodiment an image registration system executes automatic registration of images, for example medical images. In an example, semantic information is computed for each of the images to be registered comprising information about the types of objects in the images and the certainty of that information. In an example a mapping is found to register the images which takes into account the intensities of the image elements as well as the semantic information in a manner which is weighted by the certainty of that semantic information. For example, the semantic information is computed by estimating posterior distributions for the locations of anatomical structures by using a regression forest and transforming the posterior distributions into a probability map. In an example the mapping is found as a global point of inflection of an energy function, the energy function having a term related to the semantic information.Type: GrantFiled: February 11, 2011Date of Patent: July 18, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Ender Konukoglu, Sayan Pathak, Khan Mohammad Siddiqui, Antonio Criminisi, Steven White, Jamie Daniel Joseph Shotton, Duncan Paul Robertson

Publication number: 20170011203Abstract: Image-hosted data encryption implementations are presented that encrypt and decrypt data within a host image. A bit stream representing a data item and a host image are accessed. The host image has pixels which include one or more color channels that are represented by bits that are interpreted when the host image is rendered and other bits that are not interpreted when the host image is rendered. The bit stream is inserted into the host image by injecting bits into the bits of the one or more color channels not interpreted when the host image is rendered. In this way, the inserted data is not seen when the host image is rendered. Decryption involves extracting bits associated with a bit stream from the bits of the one or more color channels of the host image pixels not interpreted when the host image is rendered, and then reconstructing the bit stream.Type: ApplicationFiled: July 6, 2015Publication date: January 12, 2017Inventors: Sayan Pathak, Darshatkumar Shah

Publication number: 20090014015Abstract: While performing prostate brachytherapy in which radioactive seeds are implanted into the prostate, both X-ray and transrectal ultrasound (TRUS) data are collected. The X-ray data indicate all of the implanted seeds, but not their relative position within the prostate. The TRUS data correspond to both axial and longitudinal ultrasound images. A subset of the implanted seeds can be automatically (or manually) detected in the TRUS data (using longitudinal ultrasound images), and the prostate is indicated in the TRUS data (using axial ultrasound images). Registration is performed between the X-ray and TRUS data, thereby identifying the disposition of all implanted seeds within the prostate, enabling dosimetry to be intraoperatively determined. A medical practitioner can thus determine whether and where to implant additional seeds to achieve a desired optimal dosage and do so before the prostate brachytherapy procedure is concluded.Type: ApplicationFiled: April 16, 2008Publication date: January 15, 2009Applicant: University of WashingtonInventors: Ismail Tutar, Paul S.

Patent number: 5795296Abstract: An ultrasound system automatically measures fetal head size from ultrasound images. An ultrasound image of the fetal head is detected. A radial maxima point is identified on each of a plurality of radii extending from a substantially common vertex point within the fetal head image. Each radial maxima point corresponds to an ultrasound sample along its corresponding radius, and has a maximum ultrasound echo strength. Outlier points are removed and the curve filtered to derive an initial fetal head boundary. An inner fetal head boundary and outer fetal head boundary are derived from the initial fetal head boundary and a predetermined fetal skull thickness, and fetal head size is computed from the inner fetal head boundary and the outer fetal head boundary. Processing is allocated among multiprocessors and performed in pipeline fashion to enable real-time interactive imaging and measuring.Type: GrantFiled: February 20, 1997Date of Patent: August 18, 1998Assignee: University of WashingtonInventors: Sayan Pathak, Vikram Chalana, Yongmin Kim
