Recommendations for converting raster images to vector graphics

Question

If a person is looking to batch convert a large number of raster images into vector graphics, are there any tools out there that do that well?

For an example, think of j

Answer 1

As of today 2021.1.13,

I think Vector Magic is still the best tool on the market, they are pround to declare that on their website:

"Simply the Best Auto-Tracer in the World"
You can test out their online raster to vector conversion for free. https://vectormagic.com/

But there are, Indeed, so many techniques in Lab seems quite appearing, Like this one:
Perception-Driven Semi-Structured Boundary Vectorization

You can get their tech details and demo software here: http://www.cs.ubc.ca/labs/imager/tr/2018/PerceptionDrivenVectorization/

The result turn out to be so good, quite impressive, but the speed of conversion is quite impressive too, way too slow.

Authors of that paper are from:
1 University of British Columbia, 2 Adobe, 3 National Taiwan University

I don't know why they not do some speed optimization, build an better UI and make an awesome tool from that work.
