Abstract: An amusement park entertainment system that integrates an image of a patron into an audiovisual presentation. The patron enters a room where the lighting, sound, and scenery can be controlled. A standardized input sequence is obtained by computer automated/assisted process where user images (video cmaera input, voice parameters, etc.) prompting the user to provide certain views and voiced statements. Alternatively, photo scan or diskette/CD readers can accept user input image data. A one, two, or three dimensional image data representation of the user images is then generated, including the speech parameters of the patron. The image can later be manipulated to change the appearance of the image. This appearance change includes attire and adding tools relevant to the entertainment area used by the patron. The image can then be smoothly integrated into a preexisting audiovisual presentation, thus making the patron a synthetic actor in the production.

Abstract: A method and system for blind adaptive filtering an input signal having noise and information signal parameters that are separated by an identifier. An open loop filter stage generates an intermediate filtered signal from the noise parameters and the input signal parameters. A cost function generator generates a first cost function signal and an inverse first cost function signal from the open loop filter parameters. A residual signal is generated from the difference between the input signal and the intermediate filtered signal. Another cost function generator, coupled to the input signal and the residual signal generator, generates a second cost function signal and an inverse second cost function that maximize a stationarity feature of the residual signal. A combiner generates a combined cost function from the inverse first and second cost functions. A quasi-closed loop filter generates the filtered output signal from the intermediate filtered signal.
