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 parameters during the construction of the Gaussian scale- space in order to represent the image information in uniform distribution. At present, the scale- parameter relations between the layers of the Gaussian scale-space in many applications is not clear, which may lead to bad effect on the layers. The paper proposes an adaptive algorithm of the Gaussian scale parameters based on the scale-space of visual feature informati...
