摘要
提出了基于Flexible Image Blending算法的遥感图像镶嵌并行算法.该算法根据像素点到中心点的归一化距离计算出相应的羽化权值,克服了现有镶嵌算法需要将图像拆分为两两镶嵌的缺点,能够完全自动地对多幅遥感图像同时进行无缝并行镶嵌,并行遥感图像镶嵌实验结果表明,不仅在视觉效果上有了较大的改善,而且大大提高了执行效率,在大规模镶嵌时有着很大的性能优势.
A novel parallel mosaic approach was proposed based on Flexible Image Blending algorithm.A weighting function is obtained using the normalized distance from current pixel to the center point of each image,by which the mosaiced image is feathered.This approach overcomes the problem that multi-images must be divided into one-to-one′s mosaics,and can be used for parallel seamless mosaicing with great superiority.Experiments show that the new approach can improve both the visual quality and increase the computing efficiency.
