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.
Claims25
A skin analysis unit comprising at least one processor configured to:
- analyze an image showing skin using a hierarchical differential image filter to determine and provide a skin analysis rating, wherein the hierarchical differential image filter computes two enhancements to the image at two different levels of enhancement, determines a differential image using the two enhancements and computes the skin analysis rating from the differential image.
A method of skin analysis comprising:
- analyzing an image showing skin using a hierarchical differential image filter to determine and provide a skin analysis rating, wherein the hierarchical differential image filter computes two enhancements to the image at two different levels of enhancement, determines a differential image using the two enhancements and computes the skin analysis rating using the differential image.
A computer program product comprising a storage device storing instructions in a non-transient manner to configure one or more processors when executed to provide a skin analysis unit, the one or more processors configured to:
- analyze an image showing skin using a hierarchical differential image filter to determine and provide a skin analysis rating, wherein the hierarchical differential image filter computes two enhancements to the image at two different levels of enhancement, determines a differential image using the two enhancements and computes the skin analysis rating using the differential image.
