    Abstract: PROBLEM TO BE SOLVED: To more accurately describe the texture of a video by describing the texture descriptor of the video through the use of a feature value extracted from the respective frequency domains of frequency domain division layouts in the form of a feature vector. SOLUTION: When an arbitrary video is inputted, the inputted video is Randon-transformed. The obtained set of primary Randon transform functions is Fourier-transformed. When a video function is Randon-transformed and is Fourier-transformed, it is moved to a pole coordinate frequency domain and a video signal is transformed into a pole coordinate frequency domain. The texture feature of the video is extracted from the pole coordinate frequency domain having a prescribed frequency sampling structure. A pole coordinate system frequency domain division layout is used. In the pole coordinate system frequency domain division layout, a frequency domain is divided by a human sight recognition system. The texture descriptor of the video, which describes the texture of the video, namely, a feature vector is calculated form the feature value.

    Abstract: A texture description method in frequency domains and a texture-based retrieval method using the same, in which image signals are converted into those in a frequency domain of a Polar coordinate system. The texture description method in the frequency domain includes a first step of generating a frequency layout by partitioning the frequency domain into a set of feature channels; a second step of extracting the texture feature values of the image from the respective feature channels; and a third step of constituting a texture descriptor of the image in a vector form using the texture feature values extracted from the respective feature channels of the frequency layout. In a texture-based retrieval described in the frequency domain, a retrieval method capable of satisfying respective or all the retrieval conditions such as scale-, rotation- and intensity-invariant retrieval of relevant texture images is provided. Also, a retrieval method of computing the rough scheme of texture to provide a browsing functionality in retrieving is provided.

    Abstract: A texture description method in frequency domains and a texture-based retrieval method using the same, in which image signals are converted into those in a frequency domain of Polar coordinate system (Figure 4). The texture description method in the frequency domain comprises: a first step of generating a frequency layout (515) by partitioning the frequency domain into a set of feature channels; a second step of extracting the texture feature values of the image from the respective feature channels (512-514); and a third step of constituting a texture descriptor of the image in a vector form (516) using the texture feature values extracted from the respective feature channels of the frequency layout. According to the present invention, in a texture-based retrieval described in the frequency domain, a retrieval method capable of satisfying respective or all the retrieval conditions such as scale-, rotation- and intensity-invariant retrieval of relevant texture images is provided. Also, a retrieval method of computing the rough scheme of texture to provide a browsing functionality in retrieving is provided.
