Frequency adjustment for texture synthesis in video coding
The present disclosure relates to encoding and decoding video by employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for the texture region. Moreover, a first set of parameters is derived specifying weighting factors for reconstructing spectral coefficients of the texture region by fitting the texture region in a spectral domain to a first function of the texture patch, the first function being defined by the first set of parameters. The texture patch and the first set of parameters are then included into a bitstream which is output by an encoder and provided in this way to the decoder which reconstructs the texture based on the patch and the function applied to the patch.
Intra-Prediction Mode Concept for Block-Wise Picture Coding
An apparatus for block-wise decoding a picture from a data stream and/or encoding a picture into a data stream, the apparatus supporting at least one intra-prediction mode according to which the intra-prediction signal for a block of a predetermined size of the picture is determined by applying a first template of samples which neighbours the current block onto a neural network. The apparatus may be configured, for a current block differing from the predetermined size, to: resample a second template of samples neighboring the current block, so as to conform with the first template so as to obtain a resampled template ; apply the resampled template of samples onto the neural network so as to obtain a preliminary intra-prediction signal; and resample the preliminary intra-prediction signal so as to conform with the current block so as to obtain the intra-prediction signal for the current block.
AMINOGLYCOSIDE POTENTIATION FOR TREATMENT OF PULMONARY BACTERIAL INFECTION
The present invention provides methods and formulations for treating or preventing bacterial infection in the lungs of a subject, including for controlling P. aeruginosa infection and/or colonization in the lungs of a patient having a chronic lung condition, such as cystic fibrosis (CF), non-cystic fibrosis bronchiectasis (non-CFBE), chronic obstructive pulmonary disorder (COPD), among others. In some embodiments, the invention provides methods and formulations for treating mycobacterial infection.
Syntax prediction using reconstructed samples
An encoder and a decoder respectively encode and decode signal and syntax elements to/from a bitstream. In the encoding/decoding, semantics for the syntax elements are derived in accordance with previously decoded signal samples. Such encoding/decoding is applicable for instance to a video or audio signal.
