Adaptive algorithm of Gaussian scale parameter
Liu Li · Computer Engineering and Applications Journal · 2010
For the purpose of avoiding the problem of complicated computation or over-distortion because of losing too much key information,it is crucial to choose appropriate scale parameter during constructing Gaussian scale-space in order to represent the image information in uniform distribution.At present,many applications in Gaussian scale-space about the scale parameter is not clear,which may lead to bad effect of layer.The paper proposes a kind of adaptive algorithm of scale parameter in terms of the module of visual characters.The method is evaluated by experiment in the last section.Experimental results present the uniformly distributed information in scale-space which will be useful for higher-level image processing technologies such as object recognition.
