Pyramidal Watershed Segmentation Algorithm for High-Resolution Remote Sensing Images Using Discrete Wavelet Transforms

<table>Discrete wavelet transform of an image (single level). L—Low Pass Filter; H—High Pass Filter. LL—Approximation coefficients (High scale, low frequency)—cA<sub>1</sub>. LH, HL and HH– Detail coefficients (low scale, high frequency)—cH<sub>1</sub>, cV<sub>1</sub>  and  cD<sub>1</sub>.</table>
