Re: [hugin-ptx] Select all vertical lines and change to horizontal at once - it this possible?
Hello, sorry if I am off-topic, but I think there is something worth to mention here: http://kaiminghe.com/sig13/index.html https://github.com/duanzhibin/Rectangling-Panoramic-Images-via-Warpin When I was looking for an automated way of warping, still with no success, I've found this technique. There is also a step to detect vertical and horizontal lines inside. Would it be feasible to have such feature?

Feels like an interesting feature-request (don't know if it is a low-hanging fruit or something the devs would struggle with for months) and a description of the pros and cons of any heuristics: it constantly fails for some users. -- Sent from my Android device with K-9 Mail.

In most cases seemingly horizontal lines in real live often aren't while vertical ones often are vertical. On March 20, 2020 4:47:00 PM GMT+01:00, "David W.

Re: [hugin-ptx] Select all vertical lines and change to horizontal at once - it this possible?
The vast majority of panoramas don't have sea horizons, detecting horizontal lines would mess things up for everybody else. The code is capable of detecting horizontal lines, but the functionality is disabled. -- Bruno On 20 March 2020 07:58:57 GMT, "David W.

Re: [hugin-ptx] Select all vertical lines and change to horizontal at once - it this possible?
My use case for this is to use horizontal lines for leveling handheld strip panoramas that include sea horizons. The horizon itself never seems to be detected as a horizontal line. Yet if I rotate the image, the find vertical lines function finds the horizon as a vertical line. Maybe the question is why doesn't the point finding function find horizontal lines in the first place? What makes them different from vertical lines that they can't be found?

I think that functionality would be nice, as you outlined it. Only way I can think of now is to save the PTO after first running vertical line detector on it, edit it in text editor, search and replace to change vertical to horizontal. Save it, then reopen it in Hugin, rotate images back, and rerun vertical lines. Maybe the developers have a better idea? -- David W.
