I would like to convert PNG images/graphs to EPS without losing even a bit on resolution. All the things I tried (potrace, autotrace, using convert, gimp) the resolution is getting too bad. Any kind of help will be highly appreciated. I am using Ubuntu.

2Related: PNG to eps conversion massive increase in file size, and the article Convert png to eps, which mentions a software named "bmeps" as the solution for high-res conversion. Not tried it myself, but thought mentioning it might be helpful.– IzzyCommented Jul 10, 2014 at 13:30

I'm actually using Inkscape for bitmap vectorization. I don't know if you can directly output EPS, but i'm pretty sure converting SVG to EPS is very easily and totally lossless.– GraveenCommented Mar 17, 2015 at 15:39

Vector Magic is the best image to vector program in my humble opinion.
Here is an example jpg that I have vectorized in the following image using Vector Magic:
Here is a zoomed area of the resultant vector. Vector Magic give great flexibility to choose the number of colors and the degree of vectorization. In this example I chose 3 main colors, black, white and brown. Vector Magic detected and suggested those colors, but I could have chosen more or fewer. You can also choose the degree of vector detail. This example took me less than a minute to generate and I can regenerate on the fly... until I am happy with the result.
If you have a high quality bitmap for input you will quickly get a high quality vector with little need to tweak in illustrator (or your favorite vector package). But, even with a low resolution and image with compression artifacts, Vector Magic can detect the artifacts and provide a quality vector which may need some revision in illustrator. This will still be faster than creating the vector from scratch.
Features:
- Batchable
- Full automation, Basic or Advanced with fine-tuned control.
- Palette selection
- Anti-aliasing engine
- Artifact rejection
- Vector editing tools
- Sharp corner detection
- Path smoothing
- Background removal options
Export to EPS, SVG, PDF, AI, DXF and EMF. Works with Illustrator, Corel, and others.
This page on their site show a good comparison against alternative vectorization packages... http://vectormagic.com/home/comparisons
The software is free to try. You can't save the vector until you buy it. Test it with any bitmap and see for yourself

@panofish could you expand on your answer a bit? Currently its a link only answer. Could you add a screenshot and a bit of personal experience with that tool? Commented Mar 17, 2015 at 10:03
You can use convert from the ImageMagic package.
convert Image.png Image.eps
To install ImageMagic in Ubuntu:
sudo apt-get install imagemagick
You can also use sam2p
It’s a small application that converts raster images into bunch of different formats. You probably won’t find it in a default installation so just do:
sudo apt-get install sam2p
Note that you need to have universe enabled in your apt sources. Once you install it, the rest is easy:
sam2p Image.png EPS: Image.eps
