A method of processing optical coherence tomography (OCT) scans through a subject's skin, the method comprising: receiving at least a plurality of OCT scans through the subject's skin (7), each scan representing an OCT signal in a slice through the subject's skin (7), with the plurality of OCT scans being spaced apart such that the OCT scans represent the OCT signal through a volume through the subject's skin; processing each OCT scan using a processor so as to so as to detect at least one three dimensional structure in the skin; classifying, using a processor, the structure as belonging to a class of a plurality of classes of structures; and outputting at least one of the structure and the class.

A measuring apparatus for measuring skin perfusion pressure of an examined region in a subject, the measuring apparatus including: a measuring device configured to measure blood flow in the examined region; a detection unit configured to detect a height of the examined region; and a processing unit configured to determine the skin perfusion pressure of the examined region on the basis of a change in the blood flow in the examined region measured by the measuring device with the height of the examined region being changed and the height of the examined region being detected by the detection unit.

Systems and methods are disclosed herein for determining a diagnosis based on a base skin tone of a patient. In an embodiment, the system receives a base skin tone image of a patient, generates a calibrated base skin tone image by calibrating the base skin tone image using a reference calibration profile, and determines a base skin tone of the patient based on the calibrated base skin tone image. The system receives a concern image of a portion of the patient's skin, and selects a set of machine learning diagnostic models from a plurality of sets of candidate machine learning diagnostic models based on the base skin tone of the patient, each of the sets of candidate machine learning diagnostic models trained to receive the concern image and output a diagnosis of a condition of the patient.

A system and method for providing personalized cosmetic information objectively and scientifically present personalized cosmetics suitable for an individual's skin type by a comparative analysis between genetic skin test result data, from which an individual's skin condition can be scientifically detected, and data obtained by a phenomenological self-skin examination and a skin condition measurement instrument.

A device and method for selectively applying a composition to a treatment surface (e.g., skin) to alter an aesthetic appearance of the skin in the undereye region of the face. The device includes an applicator applying the composition to the skin, and a detector obtaining image data corresponding to an image of an area of skin. The device generates a target reflectance value based on the image data and past image data. The target reflectance value is higher than reflectance of at least half of areas corresponding to the image data and past image data. The device determines a desired level of reflectance modification for a location within the area of skin imaged by comparing image data corresponding to reflectance of the location to the target reflectance value, and directs the applicator to selectively apply the composition to the location based on the desired level of reflectance modification.

Using an optical tomography method of splitting low coherent light into sample light and reference-light, emitting the sample light to a measurement-target in a line shape, generating interference light by superimposing reflected light from the measurement-target due to emission of the sample light and the reference-light on each other, and acquiring a two-dimensional spectroscopic tomographic-image of the measurement-target by spectroscopically detecting the interference light and performing frequency analysis, an arbitrary wavelength region in an ultraviolet region is cut out from low coherent light including a wavelength region from an ultraviolet region to a visible region and the arbitrary wavelength region is shaped into a spectrum having an arbitrary wavelength width, the two-dimensional spectroscopic tomographic-image is acquired as using the low coherent light, and the penetration depth of the sample light for the measurement-target is evaluated based on the two-dimensional spectroscopic tomographic-image.

The method facilitates measuring of a tissue pressure non-invasively utilizing a negative pressure. The device has a pressure chamber, pressure sensor for measuring the pressure in the pressure chamber and a range sensor for measuring the skin tissue rising caused by the negative pressure.

Mental state analysis is performed by obtaining video of an individual as the individual interacts with a computer, either by performing various operations or by consuming a media presentation. The video is analyzed to determine eye-blink information on the individual, such as eye-blink rate or eye-blink duration. A mental state of the individual is then inferred based on the eye blink information. The blink-rate information and associated mental states can be used to modify an advertisement, a media presentation, or a digital game.
