Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional warping techniques are used to enlarge facial features, then the selected area can be modified, but visible distortion and unrealistic appearance occur in surrounding areas
Solution Approach 1:
The face is divided into multiple mesh regions with landmark points defining specific facial features. Each region can be independently deformed using separate deformation fields, allowing localized modification of selected features while preserving the natural appearance of surrounding areas. The mesh segmentation enables precise control over which areas are affected by warping operations.
Solution Approach 2:
Different deformation fields are applied to different regions of the face based on local requirements. The system assigns normalized coordinates and deformation parameters specifically to landmark points and mesh elements in the selected area, allowing high-quality realistic deformation of the target feature while maintaining natural appearance in non-selected regions.
2Ease of operation
If multiple controls are used to achieve desired modification in conventional systems, then more comprehensive control is possible, but the operation becomes cumbersome and requires iterative inputs
Solution Approach 1:
Multiple deformation fields are combined into a unified face mesh model. The system integrates deformation parameters from different facial feature modifications into a single coordinated transformation, allowing users to achieve comprehensive facial feature modifications through fewer inputs. The combined deformation fields work together to produce realistic results without requiring separate iterative adjustments for each feature.
Solution Approach 2:
The system provides real-time visual feedback by displaying the updated face mesh with combined deformation fields applied. This allows users to see the effect of modifications immediately and make single adjustments rather than requiring multiple iterative inputs. The feedback mechanism enables the system to automatically adjust and refine the deformation based on the combined fields.
3Productivity
If conventional systems process facial feature modifications, then modifications can be achieved, but memory and processor limitations prevent real-time processing
Solution Approach 1:
The face mesh is segmented into discrete regions with landmark points, allowing the system to process and store only the essential deformation parameters for each region rather than entire image data. This segmentation reduces memory requirements and enables faster processing by focusing computational resources on key facial feature points and their associated deformation fields.
Solution Approach 2:
The system transforms facial feature modifications into mathematical deformation field parameters and normalized coordinates rather than manipulating entire image pixel data. This parameter-based approach significantly reduces computational complexity and memory usage, enabling real-time processing of facial feature modifications while maintaining high quality results.

AI summary
In embodiments of facial feature liquifying using face mesh, an image processing application is implemented to modify facial features of a face in an image from a combination of deformation fields. The image processing application can generate a face mesh that includes landmark points, and then construct the deformation fields on the face mesh, where the deformation fields are defined by warpable elements formed from the landmark points. The image processing application can also combine the deformation fields. The image processing application can also receive an input to initiate modifying one or more of the facial features of the face in the image using the combined deformation fields.
