Provide some help #7

Open Gustry opened 8 years ago

Gustry commented 8 years ago

Is it possible to provide some help ? Differences between Visvalingam, Ramer and Whirlpool ? and maybe also parameters.

Thanks

I am planning to provide a detailed documentation. Just a quick note on the parameters: Visvalingham tipically needs much higher parameter value than Ramer. Whirlpool needs a little lower. I would say if Ramer needs a 1000 epsilon value, Visvalingam needs 100 000, Whirlpool needs 500. For now, I can share two links about Ramer and Visvalingam. https://en.wikipedia.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm http://bost.ocks.org/mike/simplify/

Thanks. Because I have no idea about these parameters :)
