  • Patent number: 9860530
    Abstract: A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units.

  • Patent number: 9856480
    Abstract: The invention provides DNAzymes which are capable to silence the expression of EGFR at allele-specific level. These allele-specific DNAzymes against EGFR T790M mutation will knockdown the expression of EGFR T790M mRNA while keeping EGFR wild-type mRNA intact. Hence, these allele-specific DNAzymes against EGFR T790M mutation may overcome T790M-derived TKI resistance accompanied with lower unwanted side effects on normal cells in lung cancer patients.

  • Patent number: 9817306
    Abstract: The present invention relates to an EUV pod having marks, which comprises a mask pod and one or more mark disposed on the mask pod. One or more sensor of a processing machine is used for detecting the one or more mark. By including the one or more mark, the surface roughness of one or more region of the mask pod detectable by the one or more sensor can be altered. The one or more sensor emits light to the mask pod, which reflects the light to the one or more sensor. The one or more sensor receives the reflection light from the mask pod and judges if the voltage generated by the reflection light falls within the reflection ranges of the mark. Thereby, whether the one or more sensor corresponds to the one or more make can be confirmed.

  • Patent number: 9640175
    Abstract: Systems and methods are described for adding entries to a custom lexicon used by a speech recognition engine of a speech interface in response to user interaction with the speech interface. In one embodiment, a speech signal is obtained when the user speaks a name of a particular item to be selected from among a finite set of items. If a phonetic description of the speech signal is not recognized by the speech recognition engine, then the user is presented with a means for selecting the particular item from among the finite set of items by providing input in a manner that does not include speaking the name of the item. After the user has selected the particular item via the means for selecting, the phonetic description of the speech signal is stored in association with a text description of the particular item in the custom lexicon.

  • Publication number: 20170118475
    Abstract: Methods and apparatus of compression for non-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. According to one embodiment, the system uses a RIBC (Remapped Intra Block Copy) mode, where the block vector (BV) or BV predictor is remapped using calibration data to reduce the search range. The mapped BV or BVP is also more efficient for coding. A color scaling process can be used with the RIBC mode to compensate the color/brightness discrepancy between images from different cameras. A projection-based Inter prediction method is also disclosed. The projection-based Inter prediction method takes into account different perspectives between two images captured from different cameras. Transform matrix is applied to a block candidate to project the block candidate to a position of a target block. The projected block candidate is used as a predictor for the target block.
