Title (EN) DECODER AND METHOD FOR RECONSTRUCTING SIGNAL AND ENCODER FOR ENCODING SIGNAL
(FR) DÉCODEUR ET PROCÉDÉ DE RECONSTRUCTION DE SIGNAL ET CODEUR POUR CODER UN SIGNAL
Abstract:
(EN) A method for reconstructing an uncompressed signal. The method includes obtaining an encoded signal corresponding to the signal. Obtaining side information about the signal and using the side information to obtain a prediction of dithered linear measurements of the signal. Using the prediction of the dithered linear measurements and encoded quantized dithered linear measurements to obtain quantized linear measurements of the signal based on processing each bitplane iteratively, starting from a least significant level bitplane to a most significant level bitplane. At each iteration, a prediction of each bitplane is formed using the prediction of the dithered linear measurements and the bitplanes processed in the previous iterations. Wherein each code for each bitplane is used to correct each bitplane prediction. Reconstructing the signal as a reconstructed signal using the recovered quantized dithered linear measurements, wherein the steps are performed in a processor of a decoder.
(FR) L'invention concerne un procédé de reconstruction d'un signal non comprimé. Le procédé comprend l'obtention d'un signal codé correspondant au signal. L'obtention d'informations annexes concernant le signal et l'utilisation des informations annexes pour obtenir une prédiction de mesures linéaires juxtaposées du signal. En utilisant la prédiction des mesures linéaires juxtaposées et des mesures linéaires juxtaposées quantifiées codées pour obtenir des mesures linéaires quantifiées du signal sur la base du traitement de chaque plan de bits de manière itérative, à partir d'au moins un plan de bits de niveau significatif jusqu'à un plan de bits du niveau le plus significatif. À chaque itération, une prédiction de chaque plan de bits est formée à l'aide de la prédiction des mesures linéaires juxtaposées et des plans de bits traités dans les itérations précédentes. Chaque code pour chaque plan de bits étant utilisé pour corriger chaque prédiction de plan de bits. Reconstruction du signal en tant que signal reconstruit à l'aide des mesures linéaires juxtaposition quantifiées récupérées, les étapes étant effectuées dans un processeur d'un décodeur.
