Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing montage systems are used, then facial composite images can be generated, but the results appear unnatural and lack flexibility for detailed modifications
Solution Approach 1:
The system segments the face into multiple controllable regions using a wireframe structure with landmark points. Each landmark can be independently adjusted to modify specific facial features, enabling detailed and natural modifications without affecting the entire face image.
Solution Approach 2:
The wireframe structure provides dynamic control over facial features through adjustable landmark points. Users can interactively modify the position and shape of facial features by manipulating the wireframe landmarks, allowing flexible and natural adjustments to the composite image.
2Productivity
If existing montage systems are used, then facial composite images can be generated, but post-processing requires cumbersome external software like Photoshop
Solution Approach 1:
The system merges the facial composite image generation and editing functions into a single integrated platform. The wireframe-based editing capabilities are incorporated directly into the montage system, eliminating the need for external software like Photoshop and streamlining the entire workflow.
Solution Approach 2:
The system provides multi-functional capabilities by combining image generation, wireframe-based detailed editing, and feature adjustment in one unified platform. This universal system handles both the creation and refinement of facial composite images without requiring separate tools.
3Manufacturing precision
If partial composing method is used, then specific facial features can be selected from database, but the generation process is time-consuming and less accurate
Solution Approach 1:
The system performs preliminary actions by pre-establishing a wireframe structure and landmark points on the base face image. This pre-configured framework enables rapid and accurate composition of facial features by simply adjusting the pre-positioned landmarks, significantly reducing generation time while maintaining high accuracy.

AI summary
Disclosed is an apparatus for generating a facial composite image, which includes: a database in which face image and partial feature image information is stored; a wireframe unit configured to apply a face wireframe to a basic face sketch image, the face wireframe applying an active weight to each intersecting point; a face composing unit configured to form a two-dimensional face model to which the wireframe is applied, by composing images selected from the database; and a model transforming unit configured to transform the two-dimensional face model according to a user input on the basis of the two-dimensional face model to which the wireframe is applied. Accordingly, a facial composite image with improved accuracy may be generated efficiently.
