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.
Abstract:
A profile of optical reflectance relative to a depth within a depth range from an epidermis to an upper layer of a dermis is created based on a coherence signal obtained by optical coherence tomography, an evaluation index is determined by calculating a difference between reflectance at a local minimum point and reflectance at a second local maximum point from the created profile, and skin conditions are evaluated based on the evaluation index.

A wrinkle detection method comprises the steps of obtaining face data of a subject; setting one or more analytical regions on the obtained face data; producing plural pieces of wrinkle component extracted data by extracting wrinkle components extending in one direction or in plural directions at different angles from each other in an angle range in which wrinkles tend to extend and which is set in advance for the set one or more analytical regions; producing plural pieces of wrinkle component emphasized data corresponding to the pieces of wrinkle component extracted data, respectively, by emphasizing the wrinkle components; producing composite data by combining the pieces of wrinkle component emphasized data; and detecting a wrinkle component having an intensity equal to or greater than a predetermined threshold value from the composite data as a wrinkle of the subject.
Abstract:
Provided are a structure inspection method and a structure inspection system capable of easily detecting an abnormal location and inspecting an internal state of the abnormal location in detail. The structure inspection method includes: a step of capturing a thermal image of a surface of a structure with an infrared camera; a step of detecting a first region estimated to have an internal abnormality, on the basis of the thermal image; and a step of measuring an internal state of the first region in a case where the first region is detected. In the step of measuring the internal state of the first region, the internal state of the first region is measured by capturing an image that visualizes the internal state of the first region using an electromagnetic wave or an ultrasonic wave.
