图像局部特征描述一直是图像配准与图像检索中极为重要的一部分。本文深入研究Gaussian-Hermite矩及其旋转不变矩的性质,根据尺度因子不影响其旋转不变性的特点,提出基于多尺度Gaussian-Hermite矩的图像局部特征描述方法,并通过实例与现有的特征描述方法进行详细比较。实例结果表明,所提出的方法具有更强的特征描述能力。
圖像跼部特徵描述一直是圖像配準與圖像檢索中極為重要的一部分。本文深入研究Gaussian-Hermite矩及其鏇轉不變矩的性質,根據呎度因子不影響其鏇轉不變性的特點,提齣基于多呎度Gaussian-Hermite矩的圖像跼部特徵描述方法,併通過實例與現有的特徵描述方法進行詳細比較。實例結果錶明,所提齣的方法具有更彊的特徵描述能力。

The description of image local features has been the most important part in image registration and image retrieval. In this paper, Gaussian-Hermite moments are studied and their invariants are derived. Due to that the scale parameter does not affect their rotation invariants, a descriptor based on multi-scale Gaussian-Hermite moments is proposed. Finally, the proposed descriptor is tested in a serial experiments with the state-of-the-art methods, and the experimental results show that the proposed descriptor performs much better than the others.
