Abstract
The present invention relates to a process without a therapeutic target that evaluates at least one facial clinical sign and/or evaluates make-up, in particular evaluates wrinkles or fine lines from a portion of the face, including steps consisting in: —from a sequence of facial images of a person filmed while emitting at least one sound, extract from the sequence one or more images coinciding with the emission of at least one predefined sound, —from the resulting image or images extracted, evaluate at least one facial clinical sign appearing on the image or images extracted and/or evaluate at least one characteristic related to make-up.
Claims20
A method to evaluate at least one facial clinical sign, comprising:
- from a digitized sequence of facial images of a person filmed while emitting at least one sound, extract, with a device with a processor, one or more images coinciding with the emission of at least one predefined sound, the image extraction being performed automatically based on an analysis by the device of the sound emitted;
- from the resulting image or images extracted, evaluate, with the device with the processor, at least one facial clinical sign appearing on the image or images extracted, the evaluation comprising comparing automatically by the device the images extracted with reference images.
A method to evaluate make-up, comprising:
- extract, with a device with a processor, from a digitized sequence of facial images of a person filmed while emitting at least one sound, one or more images coinciding with the emission of at least one predefined sound, the image extraction being performed automatically based on an analysis by the device of the sound emitted;
- from the resulting image or images extracted, evaluate, with the device with the processor, the hold of a make-up and its effect on facial appearance to be evaluated during facial deformations, and/or make-up visibility as a function of facial deformations, the evaluation comprising comparing automatically by the device the images extracted with reference images.
