Wavelet, английский
- Compression that is optimized for images containing low amounts of data. the relatively inferior image quality is offset against the low bandwidth demands on transmission mediums.
- A mathematical function that varies over a limited extent of time. wavelets are coming into increasing use for analyzing signals (such as sound). they have limited duration and sudden changes in frequency and amplitude rather than the infinite duration and constant amplitude and frequency, of the sine and cosine functions.
- Особый тип сжатия видеосигналов. особенно хорошо подходит для охранного телевидения. дает больший коэффициент сжатия с качеством, равным или лучшим, чем jpeg.
