Other AbstractThe definition of analytic signal and the computation algorithm for instantaneous frequencies and instantaneous ampfitudes have important significance in signal processing domain The quaternfonie analytic signal is all appropriate extension of lD analytic signal to 2D cⅡBe Whereas.the existing phase definition of quaternionic analytic signal isn’t fit for extracting instaRtaneou$frequencies of images According to the properties of quatornionic analytic signal,a novel phase definition of quaternionic analytic signal is proposed in this paper and two decomposition tools are utilized to test the effectivene9s of the definition The experimental results of synthetic and natural textures indicate that the new definition is more coincident with image intrinsic characters and advantageous for image analytic feature extraction and classification
