### I have the hyperelliptic curve y^2=x^4+81473/1024*x^2-1. How do I convert this curve to an elliptic curve in a short weierstrass form?

I have the hyperelliptic curve ~~y^2=x^4+81473/1024~~$y^2=x^4+81473/1024~~x^2-1. ~~x^2-1$. How do I convert this curve to an elliptic curve in a short weierstrass form?
Also, how can I convert the point ~~(x,y,z)=(1,i,0) ~~$(x,y,z)=(1,i,0)$ on the ~~y^2=x^4+81473/1024~~$y^2=x^4+81473/1024x^2*z^2-1*~~z^4 ~~z^4$ curve to the point on the elliptic curve?
Thanks.
