Overview
This study aims to develop a low-cost, marker-free intelligent wound assessment system that can analyze wound photos taken with a standard smartphone. By comparing wound images over time, the system will generate a quantifiable Wound Progression Index (WPI) to provide objective feedback on whether a wound is improving, stable, or worsening. The long-term goal is to support early detection of wound deterioration and improve wound care in both clinical and home settings.
Detailed description
Participants receiving routine wound care will undergo standardized wound photography during dressing changes. Longitudinal wound images will be analyzed to develop and validate a marker-free wound progression assessment method. No treatment assignment or modification of standard clinical care will occur.
Interventions
- Other Marker-free wound image registration technology
Marker-free longitudinal wound image registration and wound progression assessment using serial wound photographs.
Primary outcome measures
- Agreement between marker-free and marker-based wound progression indices [Time frame: Up to 6 months]
Secondary outcome measures (1)
- Minimum image overlap threshold for reliable analysis [Time frame: Up to 6 months]
Eligibility criteria
Inclusion criteria
- (1) Presence of a hard-to-heal wound that has remained unhealed for more than one month. (2)The wound can be photographed according to the standardized imaging protocol. (3)The participant was aged 18 years or older and provided informed consent personally or via a legally authorized representative, with a signed informed consent form.
Exclusion criteria
- Wounds whose margins could not be fully included within the imaging field.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
