Dendritic Pore Identification Through Line–Pore Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-invasive methods for evaluating skin features, such as dermascopes and confocal laser microscopes, are limited in their ability to assess larger areas of the skin, like the entire cheek or face, and require training, making them inaccessible and imprecise for many users, especially younger individuals.
Innovation Solution
A method for identifying dendritic pores by generating line and pore images from a digital image and overlaying them to detect intersections, using image processing techniques like thresholding, histogram equalization, and morphological reconstruction, to accurately identify pores intersected by lines, which are correlated with aging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dermascopes or confocal laser microscopes are used to evaluate skin features, then measurement precision is improved, but the area of examination is limited to a very small or narrow area
Solution Approach 1:
The patent segments the skin assessment task into multiple small field examinations using a dermascope, then systematically combines these segments to evaluate larger areas. The method divides the examination into discrete measurement points that can be individually assessed with high precision instruments while collectively covering extensive skin regions.
Solution Approach 2:
The patent introduces a temporal dimension by performing multiple measurements at different time points and locations, then integrating these measurements to assess overall skin condition. This transforms the limitation from a spatial constraint to a multi-temporal, multi-location assessment strategy.
2Area of stationary object
If multiple measurements are taken to examine larger areas, then the area of examination is improved, but the ease of operation deteriorates due to requiring training
Solution Approach 1:
The patent creates a standardized measurement protocol that can be replicated across multiple examination sites. By establishing consistent methods for taking measurements at different locations and times, the system enables trained users to efficiently expand examination coverage without requiring complex judgment or interpretation skills at each measurement point.
3Ease of operation
If traditional methods are used to identify skin features, then ease of operation is maintained, but measurement precision deteriorates for younger individuals with less pronounced skin features
Solution Approach 1:
The patent replaces subjective visual assessment with objective image capture and analysis. By using a dermascope to capture high-resolution images and applying systematic analysis methods, the system enhances the detectability of subtle skin features in younger individuals while maintaining operational simplicity through standardized imaging protocols.

AI summary
A method for identifying a dendritic pore is provided. Line and pore images are obtained from a digital image of a subject's skin. These line and pore images are overlaid to identify those pores having at least one line intersecting the pore as dendritic pores.
