Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for constructing line effects based on human body feature points suffer from issues such as missed gaps and line unsmoothness at transition positions, leading to low accuracy and poor display effects.
Innovation Solution
A line effect processing method that involves collecting contour points, performing point expansion to obtain vertices, generating texture curves from these vertices, and using these curves to create an effect line frame, which is then mapped onto the image to improve accuracy and smoothness.

Engineering Contradiction Analysis
1Manufacturing precision
If a strip model is constructed through human body feature points with width and curve smoothing, then the line effect can be obtained, but missed gaps and line unsmoothness occur at transition positions
Solution Approach 1:
The patent segments the line effect into multiple independent strip models, each corresponding to a specific contour point. Instead of using a single strip model that causes gaps at transitions, multiple localized strip models are generated and composite together to form the complete line effect, eliminating missed gaps and improving continuity.
Solution Approach 2:
The patent merges multiple strip models that are generated from different contour points to create the final line effect. By combining these overlapping strip models, the patent ensures continuous coverage across transition positions and achieves smooth line effects without gaps or discontinuities.
2Reliability
If contour points are collected and expanded to vertices with texture curves, then continuous smooth effect lines are achieved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-collecting contour points from the target object and pre-expanding them to vertices before generating the final line effect. This preliminary processing organizes the data structure in advance, making the subsequent texture curve generation and strip model creation more efficient and manageable despite the increased number of points.
Solution Approach 2:
The patent transitions from one-dimensional contour lines to two-dimensional texture curves by expanding contour points into vertices and generating textured strip models. This dimensional expansion adds depth and visual quality to the line effect, creating smoother and more continuous visual output despite the increased computational complexity.

AI summary
Embodiments of the disclosure provide a line effect processing method and apparatus, an electronic device, a storage medium, a computer program product, and a computer program. The method includes: collecting a plurality of contour points formed by an object contour of a target object in an image to be processed; performing point expansion processing on the plurality of contour points to obtain a plurality of vertices; generating, based on the plurality of vertices, texture curves corresponding to adjacent pairs of vertices, and obtaining at least one texture curve; utilizing the at least one texture curve to generate an effect line frame; and mapping the effect line frame onto the image to be processed to obtain a target image corresponding to the image to be processed.
