How to rasterize an image into multiple paths?

Question

SVG

On the example of the picture:

I need to get an svg with a set of paths, each of which describes the internal areas of the flower (petals, stem, leaves), which are usually painted over in coloring pages + the outer area - the background and the outline of the flower itself, black.

If you rasterize the image, then an outline/path is created along a black outline. Worked around this by pre-inverting black and white. But still, when rasterizing the image, it turns out SVG with a single path. Breaking it up into several gemmorno and not really working.

There is a feeling that this is done very simply, but somehow it does not work out.
