I'd try adaphisteq() to flatten the shading across the image. Then use a global threshold, then call imfill().

Thank you Analyst, I just try it and I´m getting a better image, really close to what im looking for, however im still mising a little bit on the side and getting some pixels that are nos supposed to be on the image, should I'm using bwareaopen to get rid of them, but at the same time I´m losing some pixels on the side.
Thanks
