| Summary: | Image Matching process in photogrammetry could be done by analog or digital ways. Expansion in technology and rise of human needs made easier way to automatically do the digital image matching process is needed. One of the method that can be used is by applying wavelet transform, in this case is one dimensional wavelet transform.<p> Wavelet transform is a technique that able to change or transform a function from spatial domain into frequency domain. Using this technique, we can see the different between high and low frequency signals from image, so we can recognize the discontinuity or noise in that signal then reduce it to get the maximum correlation value for the digital image matching process without loosing many spatial information.<p>One dimensional wavelet transform can rise the correlation value of a digital image matching process in every its ascend of decompositions level and searching image window size, mostly to homogeneous images. The best mother wavelet that can be applied is Daubechies-3, in the second level of decompositions for horizontal form and in the third level of decompositions for vertical, with size of searching image window is 61x61 pixel, which case located at SABUGA ITB, Bandung, Indonesia. |
