titile:Spatial Processing for Improved Quality Recognition of Optically
Recorded Voice Signals and Illumination Varied Scenery
abstract:
In this paper we present two image processing techniques allowing improving
the recognition quality of remote optically recorded voice signals and of
images taken under varied illumination conditions.
Regarding the voice signals the signal processing approach improves the
quality of the recording and the classification of the characteristics of
the recording while the proposed signal processing operations are applied
over the spectrogram of the optically recorded signals.
Regarding the illumination varied conditions, we present a new approach
based upon combination between spectral (of colors) manipulation called the
HSV and spatial transformation called the K-factor that is applied over the
HSV components. Such manipulation allows composing image which is both
insensitive to illumination and contains the significant spatial details of
the originally imaged object.
