چکیده
2 Fast Wavelet Transform The 2D fast wavelet transform can be represented as a convolution of the image with one-dimensional low-pass h(n) and high-pass g(n) filters (see Figure 1). This procedure results in subband images which provide the global context as well as image details at horizontal, vertical and diagonal directions. Therefore, this tool is suitable for representing numerical characters in a recognition system [1].

متن کاملWavelet Feature Extraction for the Recognition and Verification of Handwritten Numerals
Two kinds of wavelet features are proposed: (a) Kirsch edge enhancement based 2D wavelets and (b) 2D complex wavelets. The two sets of hybrid features are congregated by combining them with the geometrical features for the recognition of handwritten numerals. Experiments conducted on handwritten numeral recognition and verification show that the two hybrid feature sets can achieve high recognit...
