Devices, systems, and methods for applying cosmetic designs to biological subjects are provided. An applicator array device may include a substrate. The applicator array device may also include, a plurality of applicator elements disposed on the substrate, together defining an applicator array. Each applicator element may include an applicator member having a length substantially orthogonal to an outer surface of the substrate, a first portion of the length extending from the outer surface of the substrate and a second portion of the applicator member extending through the substrate. The first portion may define a first end and the second portion may define a second end opposite the first end. Each applicator element may also include an applicator surface defined by the first end.

A method for processing images includes: detecting a plurality of human face key points of a three-dimensional human face in a target image; acquiring a virtual makeup image, wherein the virtual makeup image includes a plurality of reference key points, the reference key points indicating human face key points of a two-dimensional human face; and acquiring a target image fused with the virtual makeup image by fusing the virtual makeup image and the target image with each of the reference key points in the virtual makeup image aligned with a corresponding human face key point.

Disclosed is a method for simulating the rendering of a make-up product on the face of a subject, using a database of reference images including, for each reference individual, images of the face with and without the makeup product. The method includes: acquiring an image of the subject face without makeup; processing the image to extract, for each spatial area of each spatial frequency range of the image, first color feature values of the spatial area; determining, among the database of reference images, reference individuals having, when wearing no makeup, color feature values similar to the first color feature values of the subject; determining, from the first color feature values of the subject, and from color feature values of the reference individuals with and without the makeup product, second color feature values; and generating a modified image of the subject face based on the second color feature values.

The presently disclosed subject matter relates to a system and method for customizing a cosmetic product. The system includes: an interface device, in electronic communication with a single batch cosmetic device. A container configured, to be imported into the single batch cosmetic device containing a base. The single batch cosmetic device configured to formulate a customized cosmetic product by mixing a cosmetic additive with the base inside the imported container using at least one mixing element. The container exported from the single batch cosmetic device containing the customized cosmetic.

A method for hair analysis of a user. The method segmenting a hair region in an image of the user to obtain a segmented hair region image; identifying one or more dominant hair colour types in; determining RGB values of pixels of the one or more dominant hair colour types; implementing a hair colour dictionary with multiple tints of plurality of hair colours classified as different hair colour names, with each of the classified different hair colour names having a relative RGB value; comparing the determined RGB values of the pixels of the one or more dominant hair colour types and the relative RGB values for the classified different hair colour types to identify the relative RGB value with a minimum distance; and determining the hair colour name corresponding to the identified relative RGB value with the minimum distance.

A battery powered blow dryer having a novel battery cooling feature to simultaneously cool the batteries and improve hair dryer performance.

An application control device according to an embodiment of the present invention has an acquisition unit that acquires image data of a skin; a division unit that divides the image data into a plurality of segments each smaller than or equal to 200 μm; and a calculation unit that calculates, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

The present invention relates to a cosmetic ink application device which functions by producing a region as an alignment marker on human skin and detecting the region to align an applicator with the skin, and a method thereof. A cosmetic ink application device according to the present invention comprises: a light source for irradiating human skin with ultraviolet light; an optical sensor for detecting intensities of fluorescence in a ultraviolet range and/or a visible light range emitted from the skin in response to the irradiation of the ultraviolet light; an applicator for applying a cosmetic ink to the skin; a head portion for holding the light source, the optical sensor, and the applicator; and a controller, wherein the controller defines a region on the skin, which emits fluorescence having an intensity different from fluorescence emitted from other regions of the skin when irradiated with the ultraviolet light, as a marker region, wherein the controller determines a position of the ink application based on the marker region, and wherein the controller causes the applicator to apply the ink on a predetermined portion of the skin.

The present invention relates to a method for identifying ingredients or compositions, based on green chemistry performance, comprising the steps of: (a) identifying a cosmetic ingredient or a cosmetic composition; (b) calculating each of; (b1) a Green Chemistry Performance Score; (b2) a Binary Score; and (b3) a Certainty Score; and (c) selecting the cosmetic ingredient or the cosmetic composition having an aggregate score above the category average.

A beauty product device is disclosed which includes a variety of sensors for sensing the way in which a user is operating the device. The sensor data can be processed and compared with pre-stored data representative of a desired style and feedback messages generated and provided back to the user to help them achieve the style they wish to achieve based on the comparison.
