    • Detecting facial landmarks in a face detected in an image may be performed by first cropping a face rectangle region of the detected face in the image and generating an integral image based at least in part on the face rectangle region. Next, a cascade classifier may be executed for each facial landmark of the face rectangle region to produce one response image for each facial landmark based at least in part on the integral image. A plurality of Active Shape Model (ASM) initializations may be set up. ASM searching may be performed for each of the ASM initializations based at least in part on the response images, each ASM search resulting in a search result having a cost. Finally, a search result of the ASM searches having a lowest cost function may be selected, the selected search result indicating locations of the facial landmarks in the image.
    • 可以通过首先裁剪图像中检测到的面部的面部矩形区域并且至少部分地基于面部矩形区域来生成整体图像来检测在图像中检测到的面部中的面部界标。 接下来,可以对面部矩形区域的每个面部标记执行级联分类器,以至少部分地基于积分图像来为每个面部标记产生一个响应图像。 可以设置多个活动形状模型(ASM)初始化。 可以至少部分地基于响应图像来对每个ASM初始化执行ASM搜索,每个ASM搜索导致搜索结果具有成本。 最后,可以选择具有最低成本函数的ASM搜索的搜索结果,所选择的搜索结果指示图像中的面部地标的位置。
