Inventor: PARI ATUL
IPC: H04N19/94
Filed: 2003-08-07
Abstract: A method and apparatus for performing motion estimation in a digital video system is disclosed (Fig.1). Specifically, the present invention discloses a system that quickly calculates estimated motion vectors in a very efficient manner (Fig.1, item 160). In one embodiment, a first multiplicand is determined by multiplying a first display time difference between a first video picture and a second video picture by a power of two scale value (Fig.1, items 150, 160). This step scales up a numerator for a ratio (Fig.1, item 120). Next, the system determines a scaled ratio by divi ding that scaled numerator by a second first display time difference between the second video picture and a third video picture. The scaled ratio is then stored calculating motion vector estimations. By storing the scaled ratio, all the estimated motion vectors can be calculated quickly with good precision since the scaled ratio saves significant bits and reducing the scale is performed by simple shifts (Fig.1, item 180).

Title: Noise spectrum estimation method and apparatus
Inventor: KAZAMA MICHIKO
IPC: G10L21/0232
Filed: 2005-03-30
Abstract: A method is provided for recurrently estimating a spectrum of noise at each signal observation interval from a sound signal which contains the noise and which is observed at each signal observation interval. In the method, there are acquired an envelope of a previous spectrum of the noise which has been previously estimated from the sound signal observed at a previous signal observation interval, and an envelope of a current spectrum of the sound signal which is observed at a current signal observation interval subsequent to the previous signal observation interval. Then, a value of correlation is computed between the envelop of the previous spectrum of the noise and the envelope of the current spectrum of the sound signal. A current spectrum of the noise contained in the sound signal observed at the current signal observation interval is estimated in accordance with the computed value of the correlation and based on the previous spectrum of the noise and the current spectrum of the sound signal.
