  abstract =     "Genetic Programming (GP) has been used for edge
                 detection, but there is no previous work that analyses
                 the outputs from a GP detector before thresholding them
                 to binary edge maps. When the threshold used in a GP
                 system slightly changes, the final edge map from a
                 detector may change a lot. Mapping the outputs of a GP
                 detector to a grayscale space by a linear
                 transformation is not effective. In order to address
                 the problem of the sensitivity to the threshold values,
                 we replace the linear transformation with an S-shaped
                 transformation. We design two new fitness functions so
                 that the outputs from an evolved detector can obtain
                 better edge maps after mapping into a grayscale space.
                 Experimental results show that the S-shaped
                 transformation obtains soft edge maps similar to the
                 fixed threshold and the new fitness functions improve
                 the edge detection accuracy.",
