Abstract: A computer-based matchmaking method utilizing numerical representations of voice as well facial features to improve matchmaking capabilities, the voice features preferably including articulation quality measures, speed of speech measures, audio energy measures, fundamental frequency measures, and relative audio periods. Certain preferred embodiments include: plastic-surgery-unique anthropometric facial measures to enhance system effectiveness; use of both standard and non-standard facial points identified by Gabor kernel-based filtering; and adapting to user preferences by adjusting system parameters based on user responses to potential matches.

Abstract: A system and a method for wavelet-based low bitrate video coding is provided. The system and method of this invention processes each frame of a video sequence based on its content. The discrete wavelet transform of each frame is taken separately. If the difference between the contents of a first frame and a second frame is above a threshold, then the wavelet transformed second frame is quantized and lossless encoded. If the difference is less than a threshold, then motion estimation is employed in wavelet domain. Then the difference between the wavelet transformed second frame and the motion compensated wavelet transformed second frame is quantized and lossless encoded. The quantization is applied by using dynamic adjustment. The quantization tables are optimized based on the coded frame characteristics. In addition to the coded frames, the lossless coded motion vectors are also transmitted to the decoder unit.
