Aspects of the subject matter described herein relate to matching product information to products. In aspects, a product matching component receives product information. The product matching component normalizes the product information and obtains keywords from the product information. By querying a database of recognized products, the keywords are used to obtain a list of products that potentially match the product information. A confidence level is assigned to each of the potential matches in the list. A match may be returned for the highest matched product or for a selectable number of products whose confidence level(s) exceed a selectable threshold.

The subject matter described herein includes methods, systems, and computer readable media for image guided ablation. One system for image guided ablation includes an ultrasound transducer for producing a real-time ultrasound image of a target volume and of surrounding tissue. The system further includes an ablation probe for ablating the target volume. The system further includes a display for displaying an image to guide positioning of the ablation probe during ablation of the target volume. The system further includes at least one tracker for tracking position and orientation of the ablation probe during the ablation of the target volume. The system further includes a rendering and display module for receiving a pre-ablation image of the target volume and for displaying a combined image on the display, where the combined image includes a motion tracked, rendered image of the ablation probe and an equally motion tracked real-time ultrasound image registered with the pre-ablation image.

Technologies may provide for detecting, validating, or confirming the validity of a handwritten signature. A logic architecture may be employed to detect a digital handwritten signature and validation data associated with a signature event, and to send the signature and the validation data to a trusted server. The logic architecture may validate the digital handwritten signature based on the signature and the validation data. Additionally, the logic architecture may present the digital handwritten signature with a reference to confirm the validity of the signature. The reference may be associated with identifying information corresponding to the event to confirm the validity of the signature.

A method and apparatus are provided for encoding with hypothetical reference decoder compliant bit allocation. The apparatus includes an encoder (100) for encoding image data for a picture in a resultant bitstream by controlling a bit allocation during the encoding of the image data responsive to satisfying requirements for a subsequent decoding of the bitstream. The requirements relate to preventing at least one of an underflow condition and an overflow condition in a buffer during the subsequent decoding of the bitstream.

Method and apparatuses are provided to enable bi-directional prediction (or bi-prediction) within P slices. A bi-predicted P slice is introduced herein as a new slice type in addition to existing I, P and B slices. A benefit of the new bi-predicted P slice is that it enables a video encoder to support temporal scalability without the need to use B pictures. Bi-predicted P slices enable the definition of a hierarchical GOP structure, which is a common method to allow temporal scalability in a video encoder. Another advantage of bi-predicted P slices is that it can improve coding efficiency over uni-directional P slices for some particular video content frames.

There are provided a method and apparatus for analytical and empirical hybrid encoding distortion modeling. An apparatus includes a distortion calculator for modeling video encoding distortion by dividing the video encoding distortion into a first portion and a second portion, calculating the first portion using empirical calculations, and calculating the second portion using analytical calculations.

The present invention relates to a full-reference (FR) objective method for assessing perceptual quality of decoded video frames in the presence of packet losses and coding artifacts. A method of assessing perceptual quality is provided. First, a value indicating an amount of distortion in a corresponding portion is accessed. Then, that value is classified as packet-loss distortion or coding-artifact distortion. Next, the classified value is modified to account for visibility differences of the human visual system, based on the classification, and then the modified values are combined for the multiple portions, to form a value indicating a total amount of distortion for the multiple portions.

The present invention provides compositions and methods for treating inflammatory bowel disease. In particular, the present invention provides methods of therapeutically treating symptoms of inflammatory bowel disease using compositions comprising an angiotensin converting enzyme (ACE) inhibitor and polyethylene glycol.
摘要:
A method of encoding video wherein multiple threads of GOPs are encoding in parallel from a buffer in a single pass. In the buffer GOPs having fewer frames than a low frame threshold at the end of a scene are merged with a preceding GOP. Hypothetical reference decoder (HRD) information is stored in the buffer for each GOP and HRD information for neighboring GOPs are merged in the buffer.
