Abstract
A digital cartoon or animation creation process, alternately describable as digital rotoscoping. Images are obtained in digital format by set-up steps (32, 44), image capture steps (34-36 and 46), and image storage (38, 48). The rotoscoping process (10) includes an image to line art rendering sub-process (14) which optionally may be followed by a specialized line art rendering sub-process (16) or a coloring sub-process (18). The line art rendering sub-process (14) includes a series of filters, particularly including a high-pass filter (68) using a gaussian blur convolution matrix. The specialized rendering sub-process (16) has particular use for carrying image regions having particularized detail through into final images in a manner that such detail is not lost, and the coloring sub-process (18) permits creation of colorized final images.
