Title To achieve image observation technology using transform method
Abstract Wavelet transform is in a landmark branch of mathematics developed in the eighties of the 20th century, S。 Mallat 1989 proposed concept of multi-resolution analysis, to construct wavelet methods are unified, and the fast algorithm of binary wavelet transform, makes wavelet transform by gradually become practical, at present, wavelet transform is mainly applied in image processing, fractal geometry, data compression, and so on the field。
In this paper, by using image texture analysis methods and techniques on the sea plane image of a series of processing, which mainly use method of wavelet transform and texture analysis method based on statistics of sea level image analysis based on signal of image texture analysis, then use gray gradient co-occurrence matrix and Tamura texture features of sea level image of sea level image feature extraction。 Through the related parameters of the sea level image texture feature extraction, and then through the calculation to get the sea surface roughness, finally, the experimental results verify the analysis, a conclusion is drawn。 In short, this paper from the near coast video surveillance of, the use of image analysis technique analysis of sea image, to study the air sea interface kinetic roughening and video image rough degree of the precise relationship, establish new based on parameters of the sea surface roughness calculation scheme。
Keywords wavelet transform Image Texture Image Roughness Gray gradient co-occurrence matrix Tamura texture feature method
