    • Image processing system and methods for aligning features suitable for use in early skin-cancer detection systems Corresponding skin features between a reference image and a later captured image are precisely aligned Curvatures are used to align body outlines of corresponding images using body-background masks An initial-displacement flow field map, generated from the aligned body outlines, may be applied to a filtered version of the later-captured image to generate a pre-warped image The pre-warped image the reference image are divided into a plurality of overlapping chips and a correlation is performed between corresponding chips A transformation map may be generated based on the chip correlations This chipping process may be iterated for successively smaller chip sizes to generate a final transform map which may be applied to the later captured image to generate a registered image having its skin feature aligned with the reference image.
    • 和图像处理系统的实施例用于对准在早期皮肤癌检测系统适合于使用特性的方法被描述英寸 的参考图像与后捕获的图​​像之间相对应的皮肤特征精确地对准。 曲率用于对准使用身体背景掩模对应图像的身体轮廓。 初始位移流场图,从对齐的身体产生的轮廓,可以是施加到稍后捕捉的图像的滤波版本以产生预扭曲图像。 所述扭曲前图像和参考图像的滤波版本被分成重叠的芯片的多个部分并加以的相关性对应的芯片之间进行。 变换映射可以基于芯片的相关性来产生。 此过程碎裂,可迭代为依次更小的芯片尺寸,以产生最终的变换图可以应用到稍后捕捉的图像,以生成具有与基准图像对准皮肤特征的配准的图像。
