Semantic Class-Based Image Enhancement System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image enhancement technologies lack the ability to accurately predict user intent and apply enhancements that align with the semantic content of images, leading to inconsistent and suboptimal results across different image types and qualities.
Innovation Solution
A method and system that assign semantic classes to digital images based on their content and apply aesthetic enhancements based on image quality and class, using a model that maps image quality and semantic classes to candidate enhancements, allowing for intent-based image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated image enhancement is applied without considering semantic content, then processing efficiency is improved, but enhancement accuracy and user satisfaction deteriorate
Solution Approach 1:
The system performs preliminary semantic classification of images into categories (e.g., portraits, landscapes, architecture) before applying enhancement operations. This preliminary action enables the subsequent enhancement process to be tailored to the specific semantic content, resolving the contradiction by maintaining high processing efficiency through automation while improving enhancement accuracy through content-aware processing strategies.
2Device complexity
If generic enhancement operations are applied to all images, then device complexity is reduced, but enhancement quality deteriorates
Solution Approach 1:
The system applies different enhancement operations and parameters based on the local semantic characteristics of each image category. For example, portrait images receive skin-tone-preserving enhancements while landscape images receive contrast and saturation enhancements. This local quality approach maintains reasonable system complexity by using category-based rules while significantly improving enhancement quality through targeted processing.
3Measurement precision
If semantic classification is added to the enhancement pipeline, then enhancement precision is improved, but processing time increases
Solution Approach 1:
The enhancement pipeline is segmented into distinct stages: semantic classification stage followed by category-specific enhancement stage. This segmentation allows the system to use efficient, lightweight classification models that quickly identify image categories without excessive processing time, while still enabling precise enhancement operations in the subsequent stage. The segmentation resolves the contradiction by optimizing each stage independently.
4Adaptability or versatility
If multiple enhancement dimensions are considered, then user intent alignment is improved, but system complexity increases
Solution Approach 1:
The system changes parameters of existing enhancement operations based on semantic class classification rather than introducing entirely new complex models. For each image category, the system adjusts enhancement parameters (e.g., contrast levels, saturation, sharpness) within the framework of standard image processing operations. This parameter-based approach improves user intent alignment by adapting to different semantic contexts while avoiding excessive system complexity.

AI summary
A method for image enhancement includes providing for a semantic class to be assigned to a digital image based on image content, the assigned semantic class being selected from a plurality of semantic classes. The method further includes providing for an aesthetic enhancement to be applied to the image based on image quality of the image and the assigned semantic class, the enhancement including at least one enhancement dimension selected from a plurality of enhancement dimensions.
