System and method for measuring skin movement and strain and related techniques
Described herein are systems and techniques for a motion capture system and a three-dimensional (3D) tracking system used to record body position and/or movements/motions and using the data to measure skin strain (a strain field) all along the body while a joint is in motion (dynamic) as well as in a fixed position (static). The data and technique can be used to quantify strains, calculate 3D contours, and derive patterns believed to reveal skin's properties during natural motions.

METHOD FOR DETERMINING A CHARACTERISTIC LENGTH OF SKIN SURFACE REPRESENTATIVE OF A QUALITY OF COLLAGENIC INTERNAL ORGANS OF A PATIENT
A non-invasive method for determining a characteristic length representative of a quality of collagenic organs of a patient, includes acquisition of at least one image of a cutaneous replica of a portion of the skin surface of the patient, the cutaneous replica being obtained from a skin patching device applied on the portion of the skin surface; processing of the acquired image in order to obtain a processed image, said processed image being formed by a plurality of geometrical shapes; extraction of a plurality of features from the plurality of geometrical shapes; determination of the characteristic length representative of the quality of the collagenic organs of the patient based on the extracted features.
System and method for applying a reflectance modifying agent to improve the visual attractiveness of human skin
A computer-controlled system determines attributes of a frexel, an area of human skin, and applies a modifying agent (RMA) at the pixel level, typically to make the skin appear more youthful and so more attractive. The system scans the frexel, identifies unattractive attributes, and applies the RMA, typically with an inkjet printer. The identified attributes relate to reflectance and may refer to features such as irregular-looking light and dark spots, age-spots, scars, and bruises. Identified attributes may also relate to the surface topology of the skin, for more precisely enhancing surface irregularities such as bumps and wrinkles. Feature mapping may be used, for example to make cheeks appear pinker and cheekbones more prominent. The RMA can be applied in agreement with identified patterns, such as adding red to a red frexel, or in opposition, such as adding green or blue to a red frexel, according to idealized models of attractiveness.
SKIN GLOSS EVALUATION DEVICE, SKIN GLOSS EVALUATION METHOD, AND SKIN GLOSS EVALUATION PROGRAM
The present invention provides a gloss evaluation device, a gloss evaluation method, and a non-transitory computer readable recording medium storing gloss evaluation program capable of evaluating gloss of skin easily and highly accurately. In the gloss evaluation device of the present invention, a skin evaluation index calculation unit 5 calculates, as a skin evaluation index, a chroma difference between a portion in which it is easy for the gloss of the face of the subject to occur and a portion in which it is difficult for gloss to occur that are set as analysis ranges, and a luster and oiliness evaluation unit 6 evaluates luster and oiliness on the basis of the chroma difference.
VISCOELASTICITY CALCULATION SYSTEM AND VISCOELASTICITY MEASUREMENT METHOD
An object of the present invention is to provide a technique of quantitatively measuring physical properties including both of viscosity and elasticity. A viscoelasticity measurement system includes a measurement apparatus, a processor, and a display apparatus.
