Hypercomplex color-sensitive smoothing filters
C J Evans, Stephen J. Sangwine, Todd A. Ell · 2002
In this paper we present a new color-sensitive low pass filter that may he tuned to smooth the color image component in the direction of the color C/sub 1/. A new method for detecting the boundaries of C/sub 1/-colored objects using the color-sensitive smoothing filter is also presented. We demonstrate the color-sensitive smoothing filter and edge detection procedure on both synthetic and natural color images.
