    A processing method for underground image of uneven illumination based on homomorphic filtering theory by LIU Yi, JIA Xu-fen, TIAN Zi-jia

    Published 2013-01-01
    “…It introduced a design scheme of novel homomorphic filter, and proposed a processing method for underground image of uneven illumination based on homomorphic filtering theory. The method uses traditional low pass filter to restrain low-frequency components and traditional high pass filter to strengthen high-frequency components, divides range of low-frequency components of underground images into two sections, and uses different processing methods in the two low-frequency sections, namely restraining low-frequency components in the range of restraining radius of low-frequency and making low-frequency components invariant which are between restraining radius of low-frequency and strengthening radius of high-frequency, so as to avoid restraining low-frequency component overly. …”

    The Effect of Higher Education on Productivity of Iranian Industries: A Comparison of Human Capital and Filter Theories by Vahid Mehrbani

    Published 2016-09-01
    “…While the human capital theory introduces higher education as a factor of productivity enhancement of labor force, but, by contrast, the filter theory denies this idea. The former contends that education as a whole phenomenon is an investment in human beings that enhances their productivity. …”
