Engineering Contradiction Analysis
1Measurement precision
If super-resolution microscopy imaging technology is used to improve spatial resolution, then resolution is improved, but imaging speed and duration are sacrificed
Solution Approach 1:
The patent replaces hardware-based super-resolution microscopy systems with a computational approach using neural networks. Instead of relying on complex optical hardware to achieve super-resolution, the system uses software-based denoising and deconvolution algorithms to enhance image resolution from standard microscopy images, thereby avoiding the speed and duration limitations of hardware-based super-resolution methods.
Solution Approach 2:
The patent creates synthetic training data by generating pairs of low-resolution/noisy images and high-resolution/clean images through computational processes. These synthetic image pairs are used to train the neural network, allowing the model to learn super-resolution mappings without requiring actual paired real-world data, thus enabling the system to achieve high resolution without the time penalties of capturing such data.
2Measurement precision
If traditional computational super-resolution methods are used, then resolution enhancement is achieved, but labor-intensive parameter tuning is required and noise robustness is poor
Solution Approach 1:
The patent implements a self-supervised learning framework where the neural network trains itself using synthetic data generated from the same imaging system's characteristics. The system automatically learns optimal parameters and noise patterns from the data without requiring manual parameter tuning or external ground truth images, making the process autonomous and eliminating labor-intensive optimization steps.
Solution Approach 2:
The patent transforms the fixed, manually-tuned parameters of traditional computational methods into learnable parameters within the neural network. The network automatically adapts parameters such as denoising strength, deconvolution kernels, and resolution enhancement factors during training, replacing manual parameter adjustment with automated learning based on the specific imaging system's characteristics.
3Measurement precision
If hardware improvements are made to optical microscopy systems, then super-resolution is achieved, but the system complexity and cost increase
Solution Approach 1:
The patent replaces complex hardware-based super-resolution microscopy systems with a computational approach using neural networks. Instead of relying on specialized optical hardware, the system uses software-based denoising and deconvolution algorithms to enhance image resolution from standard microscopy images, thereby simplifying the overall system while achieving comparable or superior resolution.
Solution Approach 2:
The patent develops a universal neural network model that can be applied to multiple types of microscopy imaging systems and various biological samples. The single trained model serves multiple functions across different imaging modalities and sample types, eliminating the need for specialized hardware for each application and reducing overall system complexity.

AI summary
A method for self-supervised microscopic image super-resolution processing, comprising: collecting original fluorescence image data of a biological sample using an optical imaging system; depending on the type of the optical imaging system performing image preprocessing on the collected original fluorescence image data using a computer, to obtain a training set, and, in the computer, training a neural network for image denoising and super-resolution processing using the training set, and using the trained neural network to process the original fluorescence image data, or using the optical imaging system to process additional fluorescence image data acquired for the same biological sample.
