GAN Image Synthesis via Segmented Feature Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generative adversarial networks (GANs) face challenges in creating realistic photos with depth that meet human scrutiny, as they are trained on two-dimensional images and struggle to replicate complex features effectively.
Innovation Solution
The approach involves pretraining multiple GANs independently to generate different synthetic images, which are then combined using an overlay model to create new images on a template or blank background, leveraging adversarial training to enhance feature creation and combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If GANs are trained on two-dimensional images, then the training process is simple and fast, but the generated images lack depth and realism
Solution Approach 1:
The patent segments the image generation process into multiple independent GAN models, each responsible for generating specific features or layers of the image. This allows each model to specialize in particular aspects while maintaining manageable training complexity for individual models.
Solution Approach 2:
The patent introduces a third dimension by stacking multiple two-dimensional GAN-generated images to create depth perception. By combining multiple 2D images with different features (e.g., foreground, background, depth layers) into a composite 3D-like structure, the system achieves realistic depth without requiring complex 3D training data.
2Manufacturing precision
If multiple GANs are used to generate different features, then the image complexity and realism improve, but the system complexity increases
Solution Approach 1:
The patent divides the overall image generation task into multiple specialized GAN models, where each model generates specific image features or layers. This segmentation allows each model to achieve high accuracy for its specific function while keeping individual model complexity low.
Solution Approach 2:
The patent merges the outputs of multiple independent GAN models into a single composite image through systematic combination methods. This merging process integrates diverse features from different models while maintaining overall system manageability through structured composition rules.
3Productivity
If GANs generate synthetic images independently, then the generation speed is fast, but the combination of features to create depth is difficult
Solution Approach 1:
The patent performs preliminary actions by having each GAN model generate its specific feature layer independently and independently optimize its output. This preliminary generation of well-defined, optimized feature layers simplifies the subsequent combination process, as each layer is already refined and ready for integration.
Solution Approach 2:
The patent resolves combination difficulties by transitioning from 2D to 3D stacking, where independent GAN-generated images are combined along the depth dimension. This dimensional transition provides a natural and systematic method for integrating multiple features while preserving the independence and speed advantages of parallel generation.

AI summary
Logic may create new images by adding more than one synthetic image on a template. Logic may provide a template with a background for a new image. Logic may provide a set of models, each model to comprise a generative adversarial network (GAN), the GANs pretrained independently to generate different synthetic images. Logic may select two or more models from the set of models. Logic may generate, by the two or more models, two or more of the different synthetic images. Logic may combine the two or more of the different synthetic images with the template to create the new image. And logic may train a set of GANs independently, to generate one of two or more different synthetic images on a blank image background, the different synthetic images to comprise a subset of the multiple features of a new image.
