Problems solved by technology

[0003] However, in the existing technology, since such a subgraph contains many nodes, even if the user only adjusts the parameters of the main color keyer node without adjusting any parameters for finer color keyer nodes, the final The generation of the chroma key image still needs to go through this subgraph, and the finer chroma key nodes

Embodiment

[0043] The present invention will be further described below by taking the chroma key processing special effect sub-graph in the special effect map of the deduction image as an example.

[0044] Among them, the deduction technique refers to subtracting the background of a single color (mostly blue and green) and replacing it with a pre-photographed background. It is also a term in post-production software, and is now used in a large number of film, television, and game productions. The principle of deduction is to subtract the unique color in the image, so as to add the desired effect.

[0045] image 3It shows a schematic diagram of processing the chroma key special effect sub-graph using the prior art. For the special effect map of the buckle image, a main chroma keyer node is often needed, and the output image of this node is a chroma key image, and the chroma keyer behind the main chroma keyer Nodes such as dilation / shrinkage, chroma key blur, and color erosion are the c...

Abstract

The invention discloses a straight through processing method and system of a special effect graph. The straight through processing method comprises the steps of: when a special effect sub-graph is created, setting all the color key fine tuning nodes for image fine tuning to be in straight through states; if any parameter of the color key fine tuning nodes is adjusted, closing the straight through states, and performing corresponding adjustment; and if the color key fine tuning nodes are not adjusted, directly transmitting main input images of the color key fine tuning nodes to subsequent nodes by inquiring straight through input indexes of the color key fine tuning nodes in a straight through processing process. By means of the method and system disclosed by the invention, the defect of low real-time property in video post processing and special effect image processing in a synthesis software in the prior art is solved, large amounts of image processing time is saved, and the image processing speed is increased.

Description

technical field [0001] The invention belongs to the technical field of video processing and synthesizing software, and in particular relates to a method and system for direct processing of special effect images. Background technique [0002] In video post-production special effects processing and synthesis software, video and images are often processed in the form of special effect graphs. The basic processing unit in the special effect graph is a node, and a node often has multiple inputs and one output. The input and output of these nodes interact with each other. Even constitutes the entire special effects map. In order to facilitate the user to use the special effect map, some classic special effect sub-pictures are often provided to the user. For example, for a deduction image (subtracting the unique color in the image to add the desired effect), the deduction image often needs a main color keyer node, and the output image of this node is a chroma key image, while In ...
