Analyzed the SIFT(Scale Invariant Feature Transform) and its Variants.
- SIFT
- PCA-SIFT
- GSIFT
- CSIFT
- SURF
- ASIFT
Summary
According to research work done by researchers ,
- SIFT and CSIFT perform the best under scale and rotation change.
- CSIFT improves SIFT under blur change and affine change, but not illumination change.
- GSIFT performs the best under blur change and illumination change.
- ASIFT performs the best under affine change.
- PCA-SIFT is always the second in different situations.
- SURF performs the worst in different situations, but runs the fastest.
