  • Hierarchical differential image filters for skin analysis
    Patent number: 10755089
    Abstract: There is provided a framework including systems and methods for analyzing skin parameters from images or videos showing skin. Using a series of Hierarchical Differential Image Filters (HDIF), it becomes possible to detect different skin features such as wrinkles, spots, and roughness. The hierarchical differential image filter computes two enhancements to an image showing skin at two different levels of enhancement, determines a differential image using the two enhancements and computes the skin analysis rating using the differential image. These skin ratings are comparably accurate to actual ratings by dermatologists.
    Type: Grant
    Filed: June 18, 2019
    Date of Patent: August 25, 2020
    Assignee: L'OREAL
