    • 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.
    • 公开了用于自动生成描绘包含皮肤的图像内的感兴趣区域(ROI)的掩模的方法和系统。 该图像可以是包含皮肤的解剖区域,例如面部,颈部,胸部,肩部,手臂或手等,或者可以是诸如脸颊,额头或鼻子等部分的区域 。 生成的面具是基于图像中的解剖特征或地标的位置,例如眼睛,鼻子,眉毛和嘴唇,其可以从主体到主体和图像到图像而变化。 因此,在描绘解剖学标准化的ROI的同时,掩模可以适应于个体主体和相同主体的不同图像,从而促进在多个对象上和/或多个图像上的标准化,可再现的皮肤分析。 此外,面罩可以限于包括皮肤均匀照射部分的皮肤区域,同时排除阴影或热点区域中的皮肤区域,否则会提供错误的特征分析结果。 还公开了用于自动登记在一种成像模式(例如,标准白光,紫外光,偏振光,多光谱吸收或荧光成像等)捕获的第一图像中描绘皮肤ROI的皮肤掩模的方法和系统, 在相同或另一成像模式中捕获的ROI的第二图像。 这种注册可以使用线性和非线性空间变换技术来完成。
