| 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.

In the claims:
1. An image rendering process, comprising:
- (a) obtaining an original image into an image channel; and
- (b) scrubbing said image channel, to enhance lines which will appear as transitions at borders of a subject in said line art representation;
- (c) scaling said image channel up in size, to render said lines more finely;
- (d) creating an alpha channel from said image channel, to denote key content appearing in said original image;
- (e) creating a monochrome channel from said image channel;
- (f) applying levels filtering to said monochrome channel, to increase contrast of low and mid-range information and thereby obtain further visual definition of said lines;
- (g) applying high-pass filtration to the monochrome channel, to filter out low frequency spatial information and thereby obtain further visual definition of said lines;
- (h) increasing contrast in said monochrome channel, to obtain further visual definition of said lines;
- (i) darkening said monochrome channel, to strengthen visual definition of said lines;
- (j) converting said monochrome channel to final size;
- (k) lining said monochrome channel, to produce consistent thin appearance of said lines; and
- (l) removing noise from said monochrome channel, thereby rendering said image channel into a rotoscope channel and producing a line art representation of said original image.
