Abstract:
A wound assessment method which can estimate a moisture level of the wound, and related image capture device. The wound area is imaged at least twice where the wound is illuminated under different illumination light intensities. The first image captured using a relatively low illumination light intensity is analyzed to assess the wound, for example measuring its size, color and texture. The second image captures using a relatively high illumination light intensity (e.g. using a flash) is analyzed to estimate the moisture level of the wound. The moisture level estimation method extracts white connected components from the second image, and estimates the moisture level based on the number, sizes, and centroid distribution of the white connected components. A 3D image of the wound may also be captured, e.g. using a structured-light 3D scanner of the image capture device.

Claim (Index 29):
An image capture device comprising:\n a camera for capturing images; a user interface screen for displaying images and information and for interacting with a user; a processor; and a computer usable non-transitory memory having a computer readable program code embedded therein which is configured to be executed by the processor to control the camera and the user interface, and to perform a process of estimating moisture level of a wound of a patient, the process comprising: (a) capturing an image of a part of the patient's body which contains the wound while illuminating the part of the patient's body by a light of a predetermined intensity; (b) extracting a wound area from the image, the wound area including a plurality of image pixels each having a pixel value; and (c) estimating the moisture level of the wound based on a subset of the plurality of image pixels in the wound area which have pixel values within a defined range; and (d) registering the estimated moisture level in a database.
