There has been a substantial amount of testing of our SIFT algorithm for i ts robustness, processing t ime and i ts efficiency to detect the keypoints and descriptors of an image, invariable of the scale, rotation and brightness.We have run the tests to check the Execution t ime for generating the Do G images, keypoints and descriptors individually.
A range of other input images ( enlarged, blurred, small, blank and with different orientations) have also been tested on the SIFT algorithm. We have been able to draw satisfactory inferences from these.
The outputs have been compared with the SIFT algorithm from other sources. We have derived a better quality of results.
The next milestone would be to reduce the execution t ime taken by SIFT. There is an on- going research on this. Suitable modifications are being made on the existing SIFT algorithm to speed up the process. Watch this space, for our next paper on SIFT which gives an insight on how the Algorithm is made to work faster and get better and more accurate results
