  • Method, device and digital camera for error control and region of interest localization of a wavelet based image compression system
    Patent number: 6141453
    Abstract: The present invention provides a method (200, 400, 500, 600), device (300, 400, 500, 600, 700) and digital camera (800) for error control of a wavelet-based image codec, wherein wavelet coefficients are encoded using entropy coding. The method includes: A) utilizing, in a decoder, control information and a plurality of resynchronization markers inserted at arbitrary positions in a wavelet-based image bitstream wherein the control information provides decoding information for decoding at least a forward sequence of wavelet coefficients; and B) detecting errors in an image bitstream and limiting propagation of errors in a decoded image utilizing the control information and the plurality of resynchronization markers.
