Document Type and Number:
Japanese Patent JP2003515230
Kind Code:
A
Abstract:
An image processing device and method for classifying symbols relies on a connected-component technique for isolating symbol regions. The device and method form connected components from an image derived by the application of an edge detection filter. The formation of connected components from this filtered image defines the edges of character shapes. As a result, the number of pixels that must be connected to define each connected component is substantially reduced and the speed of processing thereby increased. The application of the method is discussed primarily with respect to text in a video stream.
