 Genetic algorithm Euler No.

After extracting the features by this three algorithm, the template matching is done, for each individual, but the extracted features vary in size. Therefore a score normalization and fusion is required, as explained in section 5.

## 3.1 Zero Crossing Based 1-D Wavelet

The mother wavelet is defined as the second derivative of a smoothing function θ(x). The zero crossings of dyadic scales of these filters are then used to encode features. The wavelet transform of a signal *f(x)* at scale s and position x is given by
