This paper gives a method applying wavelet transformation to get the blocklines , and construct a binary control mask to supervise the phase unwrapping , and phase interpolation procedure 在這種算法中,利用小波變換尋找截?cái)嗑€,有效地標(biāo)記出極點(diǎn)和截?cái)嗑€,構(gòu)造出二元模板指導(dǎo)位相展開(kāi)。
With the ability of binary control mask to deal with under - sampling areas successfully , and with the ability of modulation ordering resulting in an optimized path , the new algorithm can be applied to complex phase unwrapping 新算法對(duì)于采樣不足的區(qū)域有著很好的處理效果,并且保留了調(diào)制度函數(shù)本身處理局部陰影等截?cái)辔幌嗖豢煽繀^(qū)域的能力。
According to the relationship between the local modulus maxima of wavelet coefficients and the local singularity , and the multiresolution analysis of wavelet transformation , the blocklines is flagged . then using the method of binary image processing and mathematical morphology to get the complete blocklines , and to construct the binary control mask . the control mask identifies valid and invalid discrete phase distribution , and remains the errors of phase unwrapping within the local confines successfully 針對(duì)直接標(biāo)記截?cái)嗑€的困難,利用小波變換系數(shù)的模極大值與局部奇異性的關(guān)系,通過(guò)檢測(cè)多尺度小波變換系數(shù)模極大值的位置來(lái)標(biāo)記截?cái)嗑€的基本走向,進(jìn)而采用二值數(shù)學(xué)形態(tài)學(xué)處理方法形成完整的截?cái)嗑€,構(gòu)成標(biāo)記出極點(diǎn)與截?cái)嗑€等易產(chǎn)生錯(cuò)誤的區(qū)域的二元模板來(lái),將位相展開(kāi)的錯(cuò)誤限制在局部范圍。
