Speech likeliness or a degree of speech is determined with a simple configuration or with a small amount of processing, and speech parts are separated from an input sound signal. The input sound signal is subjected to a waveform slicing process in frame units. The increase and decrease rate of a half wavelength in the frame is computed. The rate of a zero cross in the frame is computed. The increase and decrease rate of a half wavelength is computed by determining the rate of the portion where the upward half-wavelength or the downward half-wavelength of the waveform of the input sound signal changes to increase and decrease alternately or to decrease and increase alternately. The degree of speech is determined using each rate. Speech processing for separating or accentuating/attenuating speech and background noise in accordance with the degree of speech is performed on the sound signal for each frame.

Corresponding to the compared results of threshold values of uniformly random numbers supplied from a uniformly random number generator and pixel values of an original picture signal, each pixel value of the original picture signal is encoded. The resultant encoded picture signal is transmitted. When a decoding apparatus receives transmission data, the decoding apparatus cumulates encoded values of the transmission data for each pixel value, counts the number of cumulation times, and decodes the cumulated encoded values for each pixel value of the original picture signal corresponding to the number of cumulation times.

摘要:
A retinal disease analyzer processes data obtained by processing a color retinal image and measured visual field data provided by a perimeter to detect the condition of the optic disc and defects in the nerve fiber bundles for the clinical analysis of the condition of the optic disc and the defects in the nerve fiber bundles, and combines detected information on a fundus coordinate system taking into consideration the arrangement of the nerve fiber bundles for the comprehensive analysis of the condition and the degree of progress of glaucoma. The detected information is analyzed on the basis of the distribution pattern of the nerve fiber bundles or the corresponding fundus coordinate system to integrate all the data for analysis. The condition and the degree of progress of glaucoma can be determined on the basis of the integrated data.
