Role: Use a band-pass filter to extract edges.
Parameter translation (the order corresponds to the order of the above parameters):
Enter a picture,
Output pictures,
Input filter type (currently only'lines' mode)
description:
1. The operator applies a linear filter with a convolution mask to the image;
2. This operator is very different from the sobel_amp edge extraction operation. The edge operation extracts all edges that meet the conditions, and the operator extracts lines
3. When using this operator, the gray value at the edge of the image is mirrored, and the overflow gray value will be discarded;
