Mobile phone cartoon character creating method based on boundary tracking and pseudo-coloring

The invention discloses a mobile phone cartoon character creating method based on boundary tracking and pseudo-coloring, which comprises the following steps: (1) carrying out automatic boundary tracking on the original image, and marking the boundary; (2) carrying out manual auxiliary definition for part of the boundary; (3) separating the region within the boundary from the original image; (4) pasting the separated image into the target image; and (5) performing pseudo-coloring. The invention uses the simple and practical digital image processing algorithm, and takes care to reduce the data bulk and enhance the CPU operating efficiency, so that the mobile phone cartoon work restricted by mobile phone screen size and computing power has the advantages of low creation cost and high operation speed.
