Description

Image enhanced skin analysis Technical Field The present invention relates to a method for obtaining at least one object condition information item about an object, to a device for obtaining at least one object condition information item about at least one object, to a computer program, and to a non-transitory computer readable storage medium. The method and the device according to the invention can be used in particular in various fields or in science, for example in daily life, security technology, games, transportation technology, production technology, photography (such as digital photography or video photography for artistic, documentation or technical purposes), security technology, information technology, agriculture, crop protection, maintenance, cosmesis, medical technology. However, other applications are also possible. Background The moisture content of the skin can be analyzed by using infrared spectroscopy. The user may not typically be interested in the moisture content itself, but rather in information that may be derived from the moisture content of the skin, such as the need for skin care, early identification of disease, or health level. Therefore, a model is needed that converts skin moisture into information useful to the user. A problem with these models may be that the skin moisture level may vary between different areas of the skin, in particular facial skin. In addition, the measurement may be disturbed by local phenomena such as eczema, lesions or pimples. For some applications, the average skin moisture level may not be sufficient information to obtain meaningful results. US 6 529,67 B1 discloses a set of reference moisture values for a plurality of sample skins measured with conventional skin moisture measuring devices. A set of standard calibration equations is then provided by calculating a set of measured calibration reflectance spectra and the set of reference moisture values using multiple regression and stored in memory. The next step is to measure the skin moisture of the skin under test with reference to the set of standard calibration equations stored in memory. Skin moisture is measured in a repeatable and stable manner by using a portable skin moisture measuring device to radiate near infrared light on the skin of a subject using a near infrared reflectance spectroscopy system and to sense a set of reflectance spectra, independent of changes in temperature or humidity of the external environment. WO 2018 166 749 A1 relates to a method for determining skin moisture content, which method has various forms of embodiments. The method may comprise, for at least one skin area of the user, contacting the at least one skin area with at least one sensor contact area of a skin moisture measuring device, recording a signal related to skin moisture in the skin area, the signal being generated by means of the skin moisture measuring device, and correlating the skin moisture content with the recorded signal by comparing the recorded signal with a reference signal of known skin moisture content. According to the method, the skin moisture content may be associated with the recorded signals using a database stored in a processor-cloud architecture. WO 2023/161331 A1 relates to a method of obtaining at least one object information item about at least one object by spectroscopic measurement. The method comprises the steps of i.

WO 2021/064232 A1 relates to a system and method for diagnosing skin conditions and determining deviations from normal appearance. In one aspect, a computer-implemented method involves receiving, by an image sensor of a computing device, a plurality of images of a subject and determining, by the computing device, a region of interest for each of the plurality of images. The computer-implemented method also involves generating, by a neural network disposed within the computing device, for each of the plurality of images, a skin condition metric related to a severity of at least one skin condition exhibited by the region of interest. The computer-implemented method also involves comparing, at the computing device, the skin condition metric with one or more stored metrics, and providing, by the computing device, a titration suggestion based on the comparison.
