Engineering Contradiction Analysis
1Manufacturing precision
If high quality neural network-based super-resolution techniques are used, then image quality is improved, but computational load increases making real-time processing impossible on small or edge devices
Solution Approach 1:
The patent divides the super-resolution processing into two distinct stages: a training stage performed on powerful devices to create a lightweight neural network model, and an inference stage performed on small or edge devices using the pre-trained model. This segmentation allows high-quality image processing to be achieved on resource-constrained devices by offloading the computationally intensive model training to more powerful systems.
Solution Approach 2:
The patent performs preliminary training of the neural network model on high-performance devices before deployment to edge devices. During this preliminary action, the model learns optimal parameters and features for super-resolution processing. Once trained, the model can be executed efficiently on resource-constrained devices without requiring the same level of computational power during actual operation.
2Productivity
If conventional real-time super-resolution techniques are used, then processing speed is improved, but image quality deteriorates providing poor quality images
Solution Approach 1:
The patent changes the parameters of the neural network model through systematic training processes. By adjusting training parameters such as loss functions, optimization algorithms, and training data composition, the model achieves optimal balance between processing speed and image quality. The trained model contains optimized parameters that enable real-time processing while maintaining high output quality.
3Productivity
If neural network-based super-resolution is deployed on edge devices, then real-time processing is enabled, but device resources are overwhelmed due to high computational requirements
Solution Approach 1:
The patent extracts the computationally intensive model training process from the edge device and performs it separately on powerful training devices. Only the finalized, optimized model parameters are transferred to the edge device for inference. This extraction allows the edge device to maintain real-time processing capability without being overwhelmed by training computational requirements.
4Ease of manufacture
If standard training protocols are used for super-resolution networks, then training simplicity is improved, but generalization performance deteriorates failing to handle real-world camera-captured images
Solution Approach 1:
The patent introduces dynamic and adaptive elements into the training protocol by using diverse training datasets that include real-world camera-captured images with various imperfections. The training process adapts to different image conditions and characteristics, enabling the model to generalize better to real-world scenarios while maintaining manageable training complexity through structured approaches.
