Prototype

Implemented the prototype of the proposed CBIR system using SIFT and test with some images.Now need to improve the efficiency of that to process more images and to get best results..

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.
Met the supervisor and submitted the first progress report to academic and publication branch on 3rd July 2015.
