After adding hat function, clamping descriptor and remap float to u8, I got better result. The paper weighted each bin in descriptor with 1 - d. I don`t know why I can`t get better result. But clamp magnitude to 0.01 ~ 0.99 works fine in my implementation.
I can`t wait to try this ! So I made a simple implementation to stitch image : SIFT + Affine + RANDSAC + SVD. Replace affine model should get better result, I will try it later.
