The eyebrow is an area of thick, delicate hair above the eye that follows the shape of the lower margin of the brow ridges of some mammals. The most recent research suggests that in humans its primary function is to allow for a wider range of ‘non-verbal’ communication. It is common for people to modify their eyebrows by means of hair removal and makeup.
Near-infrared method and system for use in face detection
ActiveUS7027619B2Improve accuracyReliable face detectionImage analysisPerson identificationPattern recognitionFace detection
A method and system for use in detecting a face of a person includes providing image data representative of reflected light of a scene in at least one bandwidth within a reflected infrared radiation range. Regions of the scene in the image data which may correspond to one or both eyebrows of a person and which may correspond to one or both eyes of the person are extracted from the data. The extracted regions which may correspond to one or both eyebrows of the person are combined with the extracted regions that may correspond to one or both eyes of the person resulting in a composite feature image. The composite feature image is searched based on model data representative of an eye region to detect one or both eyes of the person.

Automatic mask design and registration and feature detection for computer-aided skin analysis
ActiveUS20090196475A1Avoiding skin regions not useful or amenableCharacter and pattern recognitionDiagnostic recording/measuringDiagnostic Radiology ModalityNose
Methods and systems for automatically generating a mask delineating a region of interest (ROI) within an image containing skin are disclosed. The image may be of an anatomical area containing skin, such as the face, neck, chest, shoulders, arms or hands, among others, or may be of portions of such areas, such as the cheek, forehead, or nose, among others. The mask that is generated is based on the locations of anatomical features or landmarks in the image, such as the eyes, nose, eyebrows and lips, which can vary from subject to subject and image to image. As such, masks can be adapted to individual subjects and to different images of the same subjects, while delineating anatomically standardized ROIs, thereby facilitating standardized, reproducible skin analysis over multiple subjects and / or over multiple images of each subject. Moreover, the masks can be limited to skin regions that include uniformly illuminated portions of skin while excluding skin regions in shadow or hot-spot areas that would otherwise provide erroneous feature analysis results. Methods and systems are also disclosed for automatically registering a skin mask delineating a skin ROI in a first image captured in one imaging modality (e.g., standard white light, UV light, polarized light, multi-spectral absorption or fluorescence imaging, etc.) onto a second image of the ROI captured in the same or another imaging modality. Such registration can be done using linear as well as non-linear spatial transformation techniques.

InactiveUS20130169827A1Low costMinimizing effortTelevision system details2D-image generationTouchscreenApplication areas
A system and method are capable of performing make-up virtual images obtained with portable devices with a digital camera. The method automatically detects points of interest (eyes, mouth, eyebrow, face contour) of the user's face image allowing the user to virtually apply make-up using fingers on a touch screen. Another algorithm was created to avoid “blurring” of make-up in the application from the user's fingers. The system allows the creation of virtual make-up faces with high accuracy. To carry out the virtual make-up, methods were created for automatically detecting points of interest in the facial image and enforcing transparency in the image to simulate the make-up and restrict the make-up application area within the region where the points of interest are found. The system allows testing cosmetics application in facial images to aid choosing colors of cosmetics before actually applying them.

A method and apparatus analyzes a scene to determine which pupils correspond to which subjects. First, a machine-readable representation of the scene, such as a camera image, is generated. Although more detail may be provided, this representation minimally depicts certain visually perceivable characteristics of multiple pupil candidates corresponding to multiple subjects in the scene. A machine such as a computer then examines various features of the pupil candidates. The features under analysis include (1) visually perceivable characteristics of the pupil candidates at one given time ("spatial cues"), and (2) changes in visually perceivable characteristics of the pupil candidates over a sampling period ("temporal cues"). The spatial and temporal cues may be used to identify associated pupil pairs. Some exemplary spatial cues include interocular distance, shape, height, and color of potentially paired pupils. In addition to features of the pupils themselves, spatial cues may also include nearby facial features such as presence of a nose / mouth / eyebrows in predetermined relationship to potentially paired pupils, a similarly colored iris surrounding each of two pupils, skin of similar color nearby, etc. Some exemplary temporal cues include motion or blinking of paired pupils together, etc. With the foregoing examination, each pupil candidate can be associated with a subject in the scene.
