我们提出了一种基于多尺度梯度的特征提取算法,可以直接应用于不规则或规则图像数据,因此可以用于范围和强度图像。我们在真实图像上使用品质因数评估技术来说明该方法的准确性,证明将该方法应用于距离图像和强度图像比将梯度算子(例如 Sobel)应用于强度图像以及分别将扫描线近似方法应用于距离图像的等效方法更准确。
We present a single multi-scale gradient-based feature extraction algorithm that can be directly applied to irregular or regular image data and hence can be used on both range and intensity images. We illustrate the accuracy of this approach using the Figure of Merit evaluation technique on real images, demonstrating that the application of this approach to both range and intensity images is more accurate than the equivalent approach of applying a gradient operator, such as Sobel, to an intensity image and, separately, the scan-line approximation approach to range images.
