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 method for transmitting variable length packets based on FEC coding. Data packets are successively and contiguously stored in a two-dimensional storage device. FEC coding is performed to generate parity packets. The parity packets are stored in the two-dimensional storage device. The data packets, offsets representing positions of the data packets in the two-dimensional storage device, types of packets, and the parity packets are then transmitted.
