Solution Overview

Problem

Existing landscape painting generation models using CycleGAN for unpaired data produce unstable results with artifacts and noise, while Pix2pix fails to decouple style and content and requires significant memory usage.

Innovation Solution

A landscape painting generation model is developed using a StyleGAN-based generative adversarial network with adaptive instance normalization (AdaIN) for style transfer, followed by a lightweight student network trained through interactive distillation with feature constraints to achieve efficient and accurate landscape painting generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If CycleGAN is used for unpaired data style transfer, then style and content can be separated, but generation stability deteriorates with artifacts and noise

Engineering Contradiction:
Improvestyle and content separationVSAvoidgeneration stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary teacher model (pre-trained StyleGAN) that provides stable style guidance without directly training on unpaired data. The student model learns from the teacher's intermediate representations, filtering out artifacts and noise while maintaining style-content separation capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses a student-teacher architecture where the student model copies useful features from the pre-trained teacher model. The teacher model generates intermediate representations that capture stable style characteristics, which the student model then uses to generate final outputs, avoiding the instability of direct unpaired data training.

Inventive Principle:
Principle #26Copying

2Reliability

If Pix2pix is used for paired data style transfer, then generation stability improves, but style and content decoupling fails and memory usage increases

Engineering Contradiction:
Improvegeneration stabilityVSAvoidstyle and content decoupling
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the generation process into distinct stages: style extraction from the teacher model, content preservation from input images, and synthesis by the student model. This segmentation allows independent optimization of style and content, achieving both stability and decoupling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pre-trained teacher model acts as an intermediary that provides stable style representations without requiring paired data. The student model uses these intermediate style features to maintain stability while achieving style-content decoupling through separate feature extraction paths.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If Pix2pix model is used, then generation stability improves, but memory usage increases and inference speed needs improvement

Engineering Contradiction:
Improvegeneration stabilityVSAvoidmemory usage
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The student model copies only the essential style transfer capabilities from the large teacher model, discarding unnecessary components. This selective copying results in a compact student model that maintains stability while reducing memory requirements and improving inference speed.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent uses a smaller student model that can be deployed efficiently, replacing the need for large Pix2pix models. The student model achieves sufficient performance with fewer resources, acting as a cost-effective alternative to memory-intensive architectures.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
