Animation image adaptation method with controllable redundancy

Abstract

The invention provides an animation image adaptation method with controllable redundancy and relates to animation content terminal adaptation of computer assistance. The method comprises the steps that 1), an input animation image is analyzed, and feature lines are extracted; 2), the redundancy is calculated according to the distribution condition of the feature lines to generate a redundancy image; 3), importance degrees of the animation image are calculated; 4), the boundary of a redundancy region is determined according to the redundancy, and a triangular grid is generated with the image boundary, the feature lines and the boundary of the redundancy region as constraint; 5), according to the screen resolution of a mobile terminal, a triangular grid of a non-redundancy region is properly deformed according to the important degree difference so that the whole grid can adapt to a screen; 6), the redundancy region is updated by adopting a mode of barycentric coordinate interpolation, and when the redundancy is larger than a set threshold value, the feature lines can be combined automatically; 7), the grain mapping function of a graphic card is utilized for embedding the image into the triangular grid, and the image is updated automatically along with changes of the grid. The algorithm is definite, an interface is friendly, and a result is robust.

Description

technical field [0001] The invention relates to computer-aided animation content terminal adaptation, in particular to a redundant controllable animation image adaptation method. Background technique [0002] With the rapid development of the mobile Internet, mobile terminals represented by smart phones are becoming the first media and information contact point for users. Mobile animation has become a potential growth point in the animation industry due to its advantages of convenience, direct interaction, and strong audience base. However, unlike animation on traditional media, mobile terminals have different resolutions, sizes, aspect ratios, etc., which makes it difficult to quickly display high-resolution source images on various terminal screens while highlighting salient areas or important areas. Object information (also known as image adaptation) becomes a growing concern. When the source image resolution and the target screen size ratio do not match, simply scaling...
