The goal of this clinical trial is to compare the evaluation of a wound area and wound tissue content made by different methods on patient population with need for directed wound healing.

The main question test of the concordance of the measurements between the evaluation of the area of a wound by the technique of transparent (Gold standard) compared to the evaluation of the area by the algorithm of a decision support system (WoundSize)

Patient wounds will be examined:

• by eye by the principal investigator
• using a ruler by the principal investigator
• by WoundCare algorithms (AKA WoundTrack) using smartphone photography by the principal investigator
• tracing the outline of the wound using a transparent sheet by the principal investigator
• by eye by a second investigator
• using a ruler by a second investigator
• by WoundCare (AKA WoundTrack) algorithms using smartphone photography by a second investigator.
• tracing the outline of the wound using a transparent sheet by the second investigator

Inclusion Criteria:

• Patient suffering from a wound requiring controlled healing ranging from 4 to 150 cm²
• Age greater than or equal to 18 years old
• Person affiliated to a social security scheme or beneficiary of such a scheme
• Person having received complete information on the organization of the research and having signed informed consent.
• Wound that can be taken in one photo in its entirety.
