specific Embodiment approach 1
[0012] Specific implementation mode one: see figure 1 , Figure 2a to Figure 2e , this embodiment consists of the following steps:
[0013] Step 1: Draw the foreground and background of the key frame in different layers, and use the initial key frame and the end key frame as the editing reference of the intermediate frame. The line editing of the key frame can use Laplace based on the gradient deformation field Editing algorithm, during the drawing process, no more than one character can be drawn in each layer to simplify the complexity of the matching algorithm;
[0014] Step 2: closing the lines of the image in each layer as a closed area;
[0015] Step 3: Use topological map matching to establish the matching relationship between the initial key frame and the end key frame area. The topological map matching also considers the nesting constraint relationship of the hierarchical map and the global and local deformation of the area shape, but the nesting of the hierarchical ...

The invention relates to a method for automatically generating a middle frame in the process of manufacturing two-dimensional cartoon which is used to solve the problem that the prior two-dimensional cartoon manufacturing software can not automatically generate the middle frame under the condition that a character image or a scene structure is relatively complex in camera lens. After the drawn line is closed to form a closed region, the matching relation of each region in each image layer is calculated; the obtained vector representation and selection character point in the matching region is subjected to character point matching; and finally, a Beizer curve is subjected to interpolation in a parameter field so as to reach the aim of automatically generating the middle frame between two key frames. Thus a cartoon manufacturer is released from a burdensome link of manufacturing the middle frame so as to inputs more energy to more creative creation.
Description
technical field [0001] The invention relates to a method for automatically generating an intermediate frame in a two-dimensional animation production process, belonging to the field of digital entertainment. Background technique [0002] In the traditional two-dimensional animation production process, the production of intermediate frames is one of the most time-consuming and laborious links. In the current two-dimensional animation production field, there is no software that can automatically generate only a few key frames Intermediate frames between keyframes. Although mainstream animation software brands on the market, such as Toonz, Toonboom, and Retas, provide some functions for automatically generating key frames, they are only applicable to the generation of intermediate frames of basic shapes such as circles and squares, and there are many limitations and limitations during use. constraint. In the actual production process of 2D animation, it often happens that mul...
