  • ICIP (2) - A NTSC-compatible compact representation for stereoscopic sequences
    Proceedings of 3rd IEEE International Conference on Image Processing, 1996
    Co-Authors: F. Labonte, C.t. Le Dinh, P. Cohen
    Abstract:

    This paper describes a new spectral compaction method for interlaced stereoscopic sequences which combines the stereo information into the spectral space of a single NTSC video channel. The method makes use of the variable spatial and stereoscopic resolution of the human visual system and relies upon the determination of an area of fixation. Spectral compaction is achieved by retaining only the high-frequency information associated with this area. A composite video signal is formed by combining the lowpass, highpass and chrominance components of both channels into the available spectral space by means of modulation and filtering operations. Compatibility of the composite video signal with the NTSC standard is ensured by using the same Colour Subcarrier for the chrominance components of one channel and a second Subcarrier whose phase is inverted on alternate fields to place the chrominance components of the second channel into the Fukinuki holes. Good quality results are obtained with relatively simple separable FIR filters.

  • ICPR - A compact representation for stereoscopic sequences with NTSC spectral compatibility
    Proceedings of 13th International Conference on Pattern Recognition, 1996
    Co-Authors: F. Labonte, C.t. Le Dinh, P. Cohen
    Abstract:

    This paper describes a new compression method for interlaced stereoscopic image sequences, which compacts the stereo information into the spectral space of a single NTSC channel. The left and right fields of the stereoscopic pairs are each decomposed into a lowpass and a highpass components. High-frequency components are limited to an area of fixation, thus allowing a reduction of their spectral extent. A composite video signal is then formed by positioning the different components in the available spectral space through filtering and modulation. Compatibility of the produced signal with the NTSC standard is ensured by using the same spectral region for the chrominance information and the same Colour Subcarrier. Good quality results are obtained with relatively simple 2D separable spatial filters at a reasonable computational cost.

  • Encoding and decoding in the 6-MHz NTSC-compatible widescreen television system
    IEEE Transactions on Circuits and Systems for Video Technology, 1991
    Co-Authors: S. Inoue, S. Kageyama, H. Uwabata, Y. Yasumoto
    Abstract:

    The Matsushita 6-MHz NTSC-compatible widescreen television system using quadrature amplitude modulation (QAM) of the video carrier and inverse Nyquist filtering is an advanced television system using the side panel method. The principle of QAM is reviewed, and the encoding and decoding processes are discussed. Methods for time expansion and time compression for each panel and very-low-frequency frequency splitting (e.g., 0.1 MHz) at a sampling frequency of 14.3 MHz are detailed. Transmitting and regenerating the Colour Subcarrier for a multiplex signal and a method of preventing noticeable differences between panels are also described.
