    Abstract

    Band-pass bilateral filter is an improved bilateral filter which does not have low-pass characteristics but has bandpass characteristics to enhance image contrast around edges. However, the computation time is relatively large due to Gaussian calculation in all pixels. To reduce the calculation cost, we look to a nonlinear filter called ε-filter and propose an advanced ε-filter which does not have low-pass charactersitics but has band-pass characteristics to enhance the image contrast around edge, namely band-pass ε-filter. Due to its simple design, the calculation cost is relatively small the same as ε-filter. To show the effectiveness of the proposed method, we also report the results of some comparative experiments concerning the filter characteristics and computational cost.
