    • Disclosed is a computer-implemented method for representing and analyzing a material having associated therewith spatial domain material-related data. The method converts the spatial domain data into frequency domain using a frequency transform function for generating frequency domain signals having frequency and magnitude composites. After converting, the method selects active regions based on a pre-defined threshold, the active regions being defined by the frequency domain signals having magnitudes above the pre-defined threshold. Further, the method generates active region coefficients by transforming the frequency domain signals related to the active regions into the spatial domain. Thereafter, the method processes the generated coefficients to construct a representation of the material which can comprise constructing an image of the material, determining and illustrating the physical characteristics of the material and/or generating a digital representation of the material and storing and/or transmitting and/or further processing said digital representation, depending on the application.
    • 公开了一种计算机实现的方法,用于表示和分析具有与其相关联的空间域材料相关数据的材料。 该方法使用频率变换函数将空间域数据转换成频域,用于产生具有频率和幅度复合的频域信号。 在转换之后,该方法基于预定义的阈值选择活动区域,有源区域由具有高于预定阈值的量值的频域信号定义。 此外,该方法通过将与有源区域相关的频域信号变换为空间域来生成有源区域系数。 此后,该方法处理生成的系数以构建材料的表示,其可以包括构建材料的图像,确定和说明材料的物理特性和/或生成材料的数字表示,并且存储和/或发送 和/或进一步处理所述数字表示,这取决于应用。
