  • Publication number: 20040264724
    Abstract: A system and method for synchronously processing ear shells for hearing aids comprising: loading data associated with a first and second ear shell; determining whether to perform a rigid or non-rigid registration of the data associated with the first and second ear shells, wherein the rigid registration is performed when shapes of the first and second ear shells are within a predetermined threshold, and the non-rigid registration is performed when the shapes of the first and second ear shells are not within the predetermined threshold; registering the data associated with the first and second ear shells; processing the first and second ear shells, wherein the processing is synchronously performed; and outputting the processed first and second ear shells to a display device.

  • Publication number: 20040165740
    Abstract: A system and method for modeling binaural shells for hearing aids, wherein the system is configured to load data associated with a first and a second ear shell. The system is further configured to register the data associated with the first and the second ear shells and process the first ear shell. The system is also configured to store data associated with processing the first ear shell and then map the data associated with processing the first ear shell to the second ear shell. Subsequently, the mapped second ear shell is interactively adjusted by an operator to compensate for an inconsistency in the mapped second ear shell.

  • Patent number: 6553131
    Abstract: An intelligent camera system and method for recognizing license plates, in accordance with the invention, includes a camera adapted to independently capture a license plate image and recognize the license plate image. The camera includes a processor for managing image data and executing a license plate recognition program device. The license plate recognition program device includes a program for detecting orientation, position, illumination conditions and blurring of the image and accounting for the orientations, position, illumination conditions and blurring of the image to obtain a baseline image of the license plate. A segmenting program for segmenting characters depicted in the baseline image by employing a projection along a horizontal axis of the baseline image to identify positions of the characters. A statistical classifier is adapted for classifying the characters. The classifier recognizes the characters and returns a confidence score based on the probability of properly identifying each character.

  • Patent number: 6473517
    Abstract: A method for segmenting and recognizing license plates, in accordance with the present invention includes capturing an image of a license plate and preprocessing the image to prepare the image for segmentation and recognition. Forward splitting regions of the license plate image into suspected characters regions, the suspected character regions are recognized in the license plate image and a confidence score is provided based on a probability of a correct match. If the suspected characters have a confidence score below a threshold value, backward merging is employed which merges adjacent suspected character regions. The backward merged suspected character regions in the license plate are recognized. If the backward merged suspected character regions have a confidence score below the threshold value, the backward merging and recognizing steps are repeated to improve the confidence score.
