Abstract:
A method for generating region frame data from video frame data, wherein said video frame data and region frame data include pixel values that define regions, said regions categorized as at least one subject region and at least one non-subject region, said method comprising:extracting said pixel values defining a subject region of the at least one subject region from said video frame data into said region frame data;assigning a non-subject pixel value in said region frame data for defining said at least one non-subject region, said non-subject pixel value indicative of a color not indicated by any of said pixel values defining said subject region; andassigning a first threshold value for pixels corresponding to the subject region and a second threshold value for pixels corresponding to the at least one non-subject region, wherein the first and second threshold values define a boundary region that is separate from the subject region and the at least one non-subject region.
