Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective methods for analyzing vortex veins in fundus images, which are crucial for ophthalmic diagnostics.
Innovation Solution
An image processing method and device that detect positions of plural vortex veins in a fundus image and compute the center of their distribution, utilizing a processor and memory to analyze fundus images captured by an ophthalmic device with a wide-angle optical system, enabling detailed imaging of the fundus, including the equatorial portion where vortex veins are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image processing methods are used, then general fundus structures can be visualized, but vortex veins cannot be effectively detected or analyzed
Solution Approach 1:
The patent segments the fundus image processing into distinct functional modules: a vortex vein detection unit that specifically identifies vortex vein positions, and a center computation unit that calculates the distribution center. This segmentation allows specialized processing for vortex veins while maintaining overall system functionality.
Solution Approach 2:
The patent introduces an intermediary processing step that computes the center of distribution from multiple detected vortex vein positions. This intermediary computation transforms scattered vortex vein detection data into a meaningful diagnostic parameter (the center point), bridging the gap between detection and clinical interpretation.
2Loss of information
If detailed analysis of vortex veins is implemented, then diagnostic information is enhanced, but system complexity increases
Solution Approach 1:
The patent extracts only the essential vortex vein position information from the complex fundus image, ignoring unnecessary details. By focusing solely on detecting vortex vein positions and computing their distribution center, the system maintains diagnostic value while avoiding the complexity of comprehensive image analysis.
Solution Approach 2:
The patent transforms the complex spatial distribution of multiple vortex veins into a simplified parameter - the center of distribution. This parameter transformation reduces the complexity of representing vortex vein patterns while preserving the essential diagnostic information about their overall arrangement.
