There are many floating-point functions in the process of fingerprint feature extraction and feature matching processes. 指纹特征提取和特征匹配的过程中,存在大量的浮点运算。
GPU was originally designed to render 3-D environment, and had powerful floating-point computation ability and the parallel feature. GPU最初是为3D图形渲染而设计的,具有强大的浮点计算能力和并行特性。
