Fractional Wavelet Filter for Camera Sensor Node with external Flash and extremely little RAM
Stephan Alexander Rein, Stephan Lehmann, Clemens Gühmann · 2008
This paper introduces the fractional wavelet filter as a technique to compute fractional values of each wavelet subband, thus allowing a low-cost camera sensor node with less than 2 kByte RAM to perform a multi-level 9/7 picture wavelet transform. The picture dimension can be 256x256 using fixed-poi
