Solution Overview

Problem

Current image restoration methods, such as Gaussian filtering, require manual design of filters for different restoration problems, leading to low efficiency and poor performance for images with varying noise types and intensities.

Innovation Solution

An image restoration method that inputs a to-be-restored image, image description information, and restoration type into an image restoration model trained with sub-restoration models corresponding to different restoration types, allowing for accurate and efficient restoration by guiding the model's attention to specific areas using target text information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual filter design is used for different restoration problems, then restoration accuracy can be maintained for specific problem types, but restoration efficiency deteriorates significantly

Engineering Contradiction:
Improverestoration accuracyVSAvoidrestoration efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the restoration task by dividing the image into multiple patches and processing each patch independently through the trained model. This allows parallel processing of multiple regions simultaneously, significantly improving efficiency while maintaining accuracy through localized restoration decisions

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces manual mechanical filter design with an automated deep learning-based image restoration model. The model is trained on diverse restoration problems and automatically selects appropriate restoration strategies, eliminating the need for manual filter design while achieving superior restoration accuracy across different problem types

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If a single restoration model is used for all restoration types, then device complexity is reduced, but restoration precision deteriorates for specific problem types

Engineering Contradiction:
Improvemodel complexityVSAvoidrestoration precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent creates a universal image restoration model that can handle multiple restoration problem types (denoising, deblurring, inpainting, etc.) within a single framework. The model is trained on diverse datasets covering different restoration tasks and uses attention mechanisms to adaptively focus on relevant features for each specific problem type, achieving high precision across all tasks without requiring separate specialized models

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If comprehensive text information is input into the restoration model, then restoration accuracy is improved through better image understanding, but processing time increases

Engineering Contradiction:
Improverestoration accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary processing by generating comprehensive text descriptions of the input image before restoration. The text encoder captures semantic information about the image content, which then guides the restoration model's attention mechanisms. This preliminary action enables the model to focus computational resources on relevant regions and features, improving accuracy while the efficient architecture minimizes the time penalty

Inventive Principle:
Principle #10Preliminary action
