OK, after playing around with it more I found out that `vote_threshold` has little effect if any, and `stepsize` makes the biggest difference. Here’s a run with some results:

```julia
julia> hough_transform_standard(tf, max_linecount = 3, stepsize = 2)
3-element Array{Tuple{Float64,Float64},1}:
 (1059.0, 0.6204604563369107)
 (1053.0, 0.6286459504838356)
 (1059.0, 0.6253717528250656)

```

Although I’m not entirely sure if that’s what I want… I’ll try to correlate that to the line’s endpoints.
