Abstract Automatic threshold choice is difficult and important to color images edge detection, First of
all, on the base of human visual properties, threshold versus intensity function of human visual system are
researched and analyzed, by using method of mathematic modeling and the result of saturation research,
function of least color difference that can be perceptible by visual systems in detecting edge is given. Finally,
we use the principle of wavelet edge detection and suggest an algorithm of automatic threshold choice
according to difference color background in wavelet edge detection. Emulate experiments demonstrate good
adaptability and edge recognition effeteness of the algorithm.
Key words wavelet edge detection; automatic threshold choice; visual properties; mathematical
modeling
