中文摘要:
      针对岩心图像由于光照不均,及其自身因素导致的拼接图像出现明显拼接缝的问题,对比分析了多种图像融合算法,并将多分辨率图像融合算法引入到岩心图像拼接中,该算法利用拉普拉斯金字塔结构将图像按频率进行分解,对各个频率上的带通图像分别进行融合,再利用金字塔反变换还原出融合结果图,最终实现了岩心图像无缝拼接。
英文摘要:
      A variety of image fusion algorithms are comparatively analyzed in order to solve the apparent seam problem caused by the non-uniform lighting and by the features of the core images themselves. The multi-resolution image fusion algorithm is introduced into the core images stitching. The Laplacian pyramid structure is used in the algorithm, which decomposes the images according to the frequency, and fuses the band-pass images at each frequency respectively. Then the inverse transform is performed to restore the fusion results of the images, and ultimately the seamless stitching of core images is achieved.
