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。
The LOG module performs a Laplacian of Gaussian filter. This filter first applies a Gaussian blur, then applies the Laplacian filter (see convolution) and finally checks for zero crossings (i.e. when the resulting value goes from negative to positive or vice versa). The end result of this ...
