Problems solved by technology

Third, mobile video and other products have high requirements on the mobile phone's processor, memory, color resolution, screen size, battery power and other hardware environments. Currently, there are not many mobile phones that can support video smoothly on the market, and the price is relatively high.
We have not yet found any reports on mobile animation character creation similar to the present invention, running on mobile phones, based on boundary tracking and pseudo-color rendering

Embodiment 1

[0067] 1. Implement boundary tracking on the original image A and mark the boundary (see figure 1 (c)):

[0068] 1. Create three temporary files:

[0069] a. Create a Tmp file to store the gray value g(x, y) of each pixel in the original image. The formula for calculating the gray value is: I=0.3B+0.59G+0.11R, where R, G, and B are the three components of the pixel of the original image;

[0070] b. Create a Tag file to store the mark t(x, y) of each pixel in the original image, so as to realize the boundary tracking based on the mark (tag), and pre-mark all the pixels as 255 (“white”);

[0071] c, set up a grayscale histogram array A (its size is 256), record the number of pixels that different grayscale values ​​have;

[0072] 2. Calculate the optimal gray threshold value T according to the gray histogram array A h :

[0073] a. Count the number of pixels in the histogram, denoted as Sum, that is

[0074] Sum = Σ i ...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, in particular to a method for creating mobile cartoon characters based on boundary tracking and pseudo-color coloring. technical background [0002] my country's mobile animation products currently mainly include animation MMS, four-frame mobile comics, animation short films and turn-based mobile games. They have the dual characteristics of both cultural products and information products: as cultural products, it is undoubtedly necessary to follow the general principles of socialist cultural products, but it is not suitable for blunt preaching, but to entertain and teach; as information products, we hope to introduce as much as possible Advanced computer technology, in order to improve product quality and improve its production efficiency. [0003] This type of product also has three distinctive features different from film, animation, audio-visual works: First, it is a "fragmen...
