然而,Laplace算子对噪声敏感,这在一定程度上限制了其在噪声图像中的应用。为了克服这一缺点,研究者们通常会在进行Laplace操作之前先对图像进行高斯平滑滤波处理,从而得到高斯-拉普拉斯算子(Laplacian of Gaussian, LoG)。此外,Laplace算子还具有旋转不变性,即其处理效果不受图像旋转的影响,这一特...
The Laplace operator is given by: The derivatives in laplace_of_gauss are calculated by appropriate derivatives of the Gaussian, resulting in the following formula for the convolution mask: AttentionNote that filter operators may return may return unexpected results if an image with a reduced domain...

The original image Convolved by a Laplacian of Gaussian filter is translated to a binary or ternary image according to threshold,in which the algorithm uses the SUSAN detector to detect corners. 新算子首先使用拉普拉斯-高斯核对图像进行卷积,并将图像转换为二值或三值图像,然后使用SUSAN算子检测角点。
