  • Patent number: 10013746
    Abstract: A method for tone-mapping a High Dynamic Range (HDR) data video stream encoded in MPEG format, the method comprising decoding the data video HDR data stream to generate decoded I-frames, auxiliary decoded data related to P-Frames, and auxiliary decoded data related to B-Frames, the method further comprising applying a tone mapping function to each decoded I-Frame to provide a tone-mapped I-Frame according to a tone mapping operator, for each P-frame depending on a reference I-frame, computing the tone-mapped P-frame from the tone-mapped I-Frame previously determined for the reference I-frame, the reference I-Frame, and the auxiliary decoding data related to the P-Frame; and, for each B-frame, computing the tone-mapped B-frame from the tone mapped I-frame previously determined for the reference I-frame, the tone mapped P-frame previously determined for the reference P-frame, and the auxiliary decoding data related to the B-Frame.

  • Patent number: 8234108
    Abstract: A method for building and contracting a linguistic dictionary, the linguistic dictionary comprising a list of surface forms and a list of normalized forms, each normalized form being associated with a surface form, the method comprising the steps of: comparing each character of a surface form with each character of the surface form's normalized form; in response to the comparing step, determining an edit operation for each character compared; and generating a transform code from the set of the edit operations in order to transform the surface form to its normalized form.
