Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for animating a single image are used, then animation can be created, but the computational resources are required to be server-side and internet connectivity is needed
Solution Approach 1:
The mobile application integrates multiple functions (image segmentation, pose estimation, 3D model generation, animation creation, and effect application) into a single device, eliminating the need for external server-side processing and internet connectivity. The application performs all animation generation tasks locally on the mobile device, making the system self-sufficient and independent of external computational resources.
2Productivity
If existing animation methods are used, then basic animation can be produced, but real-time effect application is not possible
Solution Approach 1:
The application pre-processes the input image by segmenting the body portion and generating a 3D model in advance, storing these processed elements for rapid animation generation. This preliminary processing enables real-time animation creation and effect application without requiring extensive computational resources during the animation phase, thus achieving both high productivity and versatility.
Solution Approach 2:
The application implements dynamic effect application where users can select and apply various effects (clothes substitution, background replacement, illumination effects, object addition) to animated characters in real-time. The system dynamically adjusts the animation parameters and effects based on user selections, enabling versatile effect application while maintaining real-time performance through optimized local processing.
3Manufacturing precision
If detailed body segmentation and 3D model generation are performed, then photorealistic videos are produced, but computational overhead increases
Solution Approach 1:
The application segments the input image into distinct body portions and background portions, processing each segment separately. This segmentation allows the system to focus computational resources on the essential body regions for photorealistic rendering while simplifying or pre-processing the background, thereby reducing overall computational energy consumption while maintaining high video realism quality.
Solution Approach 2:
The application creates a 3D model copy of the input image that can be reused across multiple animations and effect applications. Once the detailed 3D model is generated from the segmented body portion, this model serves as a reusable template for generating various animations and applying different effects, significantly reducing the computational energy required for subsequent processing while maintaining photorealistic quality.
