Title: Moving body detection method and apparatus and moving body counting apparatus

Abstract: A moving body detection method and apparatus which detects moving bodies by processing image data for said moving bodies, including a process in which spatial phases, which are obtained by the operational formula tan.sup.-1 (AS/AC) or cot.sup.-1 (AC/AS) (where AC is a Fourier cosine transformation and AS is a Fourier sine transformation) in a case where image signals obtained as aggregates of picture elements on the basis of picture element data constituting the image data are subjected to a spatial Fourier transformation in a direction which is not perpendicular to a direction of movement of the moving bodies, are calculated in terms of a time series; and then the moving bodies are detected on the basis of changes occurring in the calculated spatial phases.
