【摘要】 图像处理是近年来人们研究的热点,图像匹配技术是图像处理技术中颇为重要的部分,SIFT算法是其发展的重要根基。由于SIFT算法有其自身局限性,提出了将图像增强技术与SIFT算法结合起来,以增加图像特征点的数量。采用了直方图均衡化和拉普拉斯增强进行处理,并提出了一种改进的图像增强算法。最后以实验验证了该方法的可行性。更多还原

【Abstract】 Image processing is a hot topic in recent years. Image matching is an important part of image processing. The SIFT algorithm is an important foundation for its development. Because SIFT algorithm has its own limitations, this paper proposes to combine image enhancement and SIFT algorithm to increase the number of image feature points. Histogram equalization and Laplacian enhancement are used for processing, and an improved image enhancement algorithm is proposed. Finally, the feasibility of the method is verified by experiments.更多还原
