20130301703 | METHOD OF CONTENT ADAPTIVE VIDEO ENCODING - A method of content adaptive encoding video comprising segmenting video content into segments based on predefined classifications or models. Based on the segment classifications, each segment is encoded with a different encoder chosen from a plurality of encoders. Each encoder is associated with a model. The chosen encoder is particularly suited to encoding the unique subject matter of the segment. The coded bit-stream for each segment includes information regarding which encoder was used to encode that segment. A matching decoder of a plurality of decoders is chosen using the information in the coded bitstream to decode each segment using a decoder suited for the classification or model of the segment. If scenes exist which do not fall in a predefined classification, or where classification is more difficult based on the scene content, these scenes are segmented, coded and decoded using a generic coder and decoder. | 2013-11-14 |
20130301704 | VIDEO CODING / DECODING WITH RE-ORIENTED TRANSFORMS AND SUB-BLOCK TRANSFORM SIZES - Techniques and tools for video coding/decoding with sub-block transform coding/decoding and re-oriented transforms are described. For example, a video encoder adaptively switches between 8×8, 8×4, and 4×8 DCTs when encoding 8×8 prediction residual blocks; a corresponding video decoder switches between 8×8, 8×4, and 4×8 inverse DCTs during decoding. The video encoder may determine the transform sizes as well as switching levels (e.g., frame, macroblock, or block) in a closed loop evaluation of the different transform sizes and switching levels. When a video encoder or decoder uses spatial extrapolation from pixel values in a causal neighborhood to predict pixel values of a block of pixels, the encoder/decoder can use a re-oriented transform to address non-stationarity of prediction residual values. | 2013-11-14 |

The X-ray imaging apparatus includes an X-ray generator to generate X-rays and irradiate the generated X-rays, an X-ray detector to detect the irradiated X-rays and output X-ray data by counting the number of photons having an energy that is equal to or greater than threshold energy among photons contained in the detected X-rays, for each of a plurality of pixels; a function acquisition unit to acquire calibration functions for the respective pixels using X-ray data output for a plurality of predesigned phantoms, and an image correction unit to correct an X-ray image of an object on a per pixel basis using the acquired calibration functions. | 2013-11-14 |
20130301800 | ORTHOVOLTAGE RADIOTHERAPY - Radiosurgery systems are described that are configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, and in some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, a fiducial marker is used to identify the location of the target tissues. | 2013-11-14 |
20130301801 | POWER AND COMMUNICATION INTERFACE BETWEEN A DIGITAL X-RAY DETECTOR AND AN X-RAY IMAGING SYSTEM - A system for eliminating image artifacts caused by electromagnetic interference (EMI) on a portable digital x-ray detector that is capable of non-contact wireless inductively coupled power transfer and capacitively coupled communication and data transfer. An X-ray imaging system comprising a portable digital X-ray detector inductively and capacitively coupled to a power source and communication device that is coupled to a detector receptacle of the X-ray imaging system when the portable digital X-ray detector is located within the detector receptacle to transfer power from a power supply of the power source and communication device to the portable digital X-ray detector and transfer communication and data between the power source and communication device and the portable digital X-ray detector. | 2013-11-14 |
20130301802 | RADIOGRAPHIC IMAGE PHOTOGRAPHING SYSTEM - The radiographic image photographing system includes an information acquisition member which acquires information on the radiographic image photographing device from an information presentation member of the radiographic image photographing device in a non-contact manner. When the information acquisition member makes the notification of the acquired information on the radiographic image photographing device, the management apparatus notifies the wireless communication member of the radiographic image photographing device of an identifier dedicated to an access point correlated with the information acquisition member. The wireless communication member of the radiographic image photographing device conducts wireless communication with the access point using a general-purpose identifier in a default state, and using the identifier dedicated to the access point after receiving the notification of the identifier dedicated to the access point from the management apparatus. | 2013-11-14 |
