Summary:The embodiment of the present invention relates to the field of fingerprint recognition, and discloses a fingerprint extraction method and apparatus. The fingerprint extraction method comprises: acquiring the sensing pixel value of each pixel point in a fingerprint sensing area when a finger touch is detected; recognizing the line feature corresponding to each pixel point according to a mixed Gaussian background model of the sensing pixel value of each pixel point and a preset pixel point; and generating a fingerprint image of a finger according to the line feature corresponding to each pixel point. The present invention also provides a fingerprint extraction device. According to the present invention, based on a fingerprint extraction image of the mixed Gaussian background model, a fingerprint image with high quality can be obtained. 本发明实施例涉及指纹识别领域，公开了种指纹提取方法及装置。本发明的指纹提取方法包括：当检测到手指触摸时，获取指纹感应区域中每个像素点的感应像素值；根据每个像素点的感应像素值与预设的每个像素点的混合高斯背景模型，识别每个像素点对应的纹路特征；根据每个像素点对应的纹路特征，生成手指的指纹图像。本发明还提供了种指纹提取装置；本发明中，基于混合高斯背景模型提取
