How to convert a raster image in poor quality to vector graphics?

Question

Adobe Illustrator

We need to convert the palm into vector graphics, but what if it's in poor quality?

Answer 1

It is probably in this case that it is easier and faster to draw in illustrator, it will take about 15 minutes at most.
If it were not so detailed, then photoshop could be enlarged and, through multiple overlays of a duplicate image filtered by high pass, achieve a higher resolution. Well, trace later in illustrator

Answer 2

Select only the palm in the picture, save, find better quality through Google image search, trace through the sketch in illustrator, a minute of work

Answer 3

It will be much easier to just draw on the pattern.
