About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
(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.
Disqualifiers
Wounds whose margins could not be fully included within the imaging field.
Trial population
Adult patients with hard-to-heal wounds located on body sites that can be fully captured within a single standardized image.

Trial outcomes
Primary outcomes
Agreement between marker-free and marker-based wound progression indices
To evaluate the agreement between the Marker-Free Wound Progression Index (WPI\_MF) and the gold-standard marker-based Wound Progression Index (WPI\_GS) derived from longitudinal wound photographs.
Secondary outcomes
Minimum image overlap threshold for reliable analysis
To determine the minimum overlap ratio required to achieve statistically acceptable agreement.
