Abstract: A method of detecting a target includes generating an image pyramid based on an image on which a detection is to be performed; classifying candidate areas in the image pyramid using a cascade neural network; and determining a target area corresponding to a target included in the image based on the plurality of candidate areas, wherein the cascade neural network includes a plurality of neural networks, and at least one neural network among the neural networks includes parallel sub-neural networks.

Abstract: Disclosed is a liveness test method and apparatus. A liveness test apparatus determines a pre-liveness score based on a plurality of sub-images acquired from an input image, determines a post-liveness score based on a recognition model for recognizing an object included in the input image, and determines a liveness of the object based on any one or any combination of the pre-liveness score and the post-liveness score.

Abstract: Provided is a 3D registration method and apparatus that may select a key point from among plural points included in 3D target data, based on a geometric feature or a color feature of each of the plural points, may adjust a position of the selected key point of the 3D target data based on features of, or a distance between, a key point of the 3D source data and the selected key point of the 3D target data, may calculate reliabilities of plural key points of the 3D source data based on respective features of at least one key point of the 3D target data determined to correspond to the plural key points of the 3D source data, and may generate 3D registration data by performing 3D registration between the 3D source data and the 3D target data based on the calculated reliabilities.
Abstract translation: 提供了一种可以基于多个点中的每一个的几何特征或颜色特征来选择包括在3D目标数据中的多个点中的关键点的3D登记方法和装置，可以调整所选择的关键点的位置 基于3D源数据的关键点和3D目标数据的所选关键点之间的特征或距离的3D目标数据可以基于3D源数据的各个特征来计算3D源数据的多个关键点的可靠性 所述3D目标数据的至少一个关键点被确定为对应于所述3D源数据的所述多个关键点，并且可以基于所计算的可靠性通过在所述3D源数据和所述3D目标数据之间执行3D注册来生成3D注册数据。
