A discrete wavelet transform (DWT) technique to calculate the spacing of moire pitches is proposed. The moire pattern image obtained with various resolutions are analyzed. By using the proposed DWT, the moire pattern image is transformed into a periodic waveform. This application indicates that the approach is very robust to noise and distortion.
