  • Digital image processing method transforming a matrix representation of pixels into a vector representation
    Patent number: 7689060
    Abstract: A method for transforming a matrix representation of pixels of an image into a vector representation of the image involves partition of the image into contiguous homogeneous regions by applying a watershed type morphologic algorithm to the matrix representation of pixels and identifying the contours of the contiguous homogeneous regions by applying a vector code contouring algorithm of the chain-code type to every region. By selecting quantization level of the gradient, improved image quality, dimensions and noise are achieved.
    Type: Grant
    Filed: October 27, 2005
    Date of Patent: March 30, 2010
    Assignee: STMicroelectronics SRL
    Inventors: Giuseppe Messina, Mirko Ignazio Guarnera, Agostino Costanzo, Sebastiano Battiato, Giovanni Gallo, Salvatore Nicotra
