B404 可視化画像のウェーブレット解析(第2報)

This paper describes an image analysis by multiresolution technique, which is the same kind of the method as the so-called dyadic wavelet analysis. In the case of homogeneous images such as the tracer images by particle or mist, it is possible to obtain the characteristics of images using the histogram of gray level of high-frequency passed image data. The differentiation of the signal data with the different scale (resolution) means the analysis of spatial frequency of images. The variance of the luminance distribution has a relationship with the entropy. The fractal is not strong in these images.
