Edge Based Template Matching

Different

These differences can write less code and use opencv acceleration

1 Use Canny directly

The reference article implements the Canny algorithm itself.
Inserts the operation that creates the gradient template into it.

The implementation here is different.
First use Canny algorithm to find the edges.
Then use FindContours find the edges to create a gradient template.

2 Use CartToPolar to get magnitude

Referencing the article by traversing the calculation magnitude.

Here use the opencv's CartToPolar to get the magnitude and direction directly
