it introduces an independent edge self-reinforcement algorithm to link edge curves and strengthen the salient edges . according to the reinforced results, the salient edges of the image could be easily extracted, and the image features are thus described by those salient edges 它利用獨(dú)立邊界自增強(qiáng)算法來(lái)連結(jié)邊緣和增強(qiáng)顯著邊緣,依靠增強(qiáng)后的結(jié)果,就能夠較容易地提取圖象中的顯著邊緣,使用顯著邊緣的特征代表圖象的形狀特征。
3 ) for weak noise interferogram or filtered interferogram, dyadic wavelet can be used to detect fringe edges . a gvf snake model was used to link discrete edges, the linked edges were kept well accordance with fringes of phase map . 4 ) phase unwrapping algorithm based on edge detection is suitable to well separated fringes, the unwrapped phase can be rewrapped to the original phase map 4)對(duì)于低噪聲情況下或?yàn)V波后的干涉條紋圖,在基于邊緣檢測(cè)的相位解纏過(guò)程中,利用snake模型可以高效準(zhǔn)確的實(shí)現(xiàn)邊緣點(diǎn)的連接,所連接的邊緣線與干涉條紋很好的吻合,可將連線的精度控制在三個(gè)像元。
