摘要:

以图像轮廓角点为特征,采用B-spline实现图像的缩放,通过模版匹配寻找拼接位置,并利用小波变换简化模版匹配算法的计算过程,提高了算法的抗噪能力。实验结果表明,该算法的运算速度和拼接效果均比较理想。

关键词: 图像拼接, 模版匹配, 小波变换

Abstract: The zoom of the images is implemented by using B-spline with the character of the image outline angular point. The mosaic position is found through template matching. The computation of template matching algorithm is simplified by using wavelet transform, which enhances its noise-immune ability. Experimental results show the calculation speed and the mosaic effect of this algorithm are both well.

Key words: image mosaic, template matching, wavelet transform
