    摘要: A wavelet inverse transform method includes a decoding object coefficient extracting step of extracting only coefficients necessary for decoding a specified area from wavelet transform coefficients, and a wavelet inverse transform step of inverse transforming coefficients extracted from the decoding object coefficient extracting step. The decoding object coefficient extracting step extracts transform coefficients not only inside the specified area but also those outside the specified area. This enables only an optional partial picture to be decoded without decoding the entire picture. A corresponding wavelet inverse transform device is also disclosed.

    摘要: In wavelet transform encoding, high-quality encoding is to be realized by enabling picture quality control from one fractional area to another. An input picture 100 is read out in an amount corresponding to a number of lines required for wavelet transform and buffered in a memory unit 6. The input picture then is wavelet transformed in a wavelet transform unit 2 and quantized in a coefficient quantizing unit 3. In quantizing wavelet transform coefficients, the wavelet transform coefficients are multiplied by weighting coefficients from one sub-band to another. The weighting coefficients are determined using the analysis information of a specified block area in a picture, such as motion information and texture fineness information. This enables fine quantization control in terms of a picture block as a unit.

    摘要: The present invention relates to an image coding apparatus/method, an image decoding apparatus/method, and a transmission medium, which conduct high-efficiency coding or decoding of an image, and applicable in a system performing efficient transmission or accumulation of images. In coding an image after splitting the image into a plurality of bands, the invention is characterized in a process comprising the steps of splitting the image into a plurality of bands, applying quadrature transformation to the images of the resultant band components, quantizing the resultant quadrature transformation coefficients, and generating a coded bit stream by variable-length-coding the quantization coefficient. This permits coding less susceptible to block strain at a high compression ratio.

    摘要: A coupling device, having a simple structure, prevents leakage of fluid from an auxiliary valve in a female coupler. The coupling device seals fluid containing air in the female coupler, even in the pressure of the fluid remains or is as low as the ambient pressure level when the male coupler is separated from the female coupler. An annular seal, having integrally formed first and second annular seal elements, is provided in the female coupler. The first annular seal seals between a protruded cylindrical member of the male coupler and a mating cylindrical member of the female coupler. The second annular seal forms a valve body portion of the cylindrical member of the female coupler.
