  • Patent number: 9460521
    Abstract: The present invention provides a method for analyzing a digital image comprising a plurality of pixels representing a scene. The method comprising steps of obtaining pixel chromaticity information, providing, combinations each having a corresponding surface and a corresponding illuminant, performing a global scene surface-illuminant classification by determining hypothesis scores, accumulating hypothesis scores, thereby obtaining a global illuminant/surface statistic representing an estimate of a distribution of illuminants and/or surfaces in the scene as represented by the digital image. Other methods are also provided. Apparatuses for carrying out the methods are also provided.
    Type: Grant

  • Patent number: 7877252
    Abstract: An automatic speech recognition method includes converting an acoustic signal into a digital signal; determine a power spectrum of at least one portion of the digital signal; and non-linearly determining envelope values of the power spectrum at a plurality of respective frequencies, based on a combination of the power spectrum with a filter function. Non-linearly determining envelope values involves calculating each envelope value based on a respective number of values of the power spectrum and of the filter function and the respective number of values is correlated to the respective frequency of the envelope value.
