| Summary: | Near duplicated images refer to a pair of images in which one is close to the exact
duplicate of the other, but different in the capturing conditions, times, rendering
conditions, and/or editing operations.
Near Duplicate Image Identification (NDII) is a computer vision problem. It is more
challenging to identifying near duplicate images with difference in variation and
scale. Spatially Aligned Pyramid Matching (SAPM), a multi-level matching method
which is proposed by D. Xu el at robustly handles spatial shifts as well as scale
changes.
SAPM was implemented and experiment was done to test on effectiveness of SAPM
on NDII. The result clearly shows that SAPM is capable in identifying duplicate image.
A prototype was created to illustrate the use of SAPM in NDII.
To Improve SAPM efficiency and effectiveness, different features detector and other
clustering method can be tested or analysed. Near Duplicate Video Identification
(NDVI) can be implemented with SAPM and recently proposed video matching
framework Spatio-Temporal Pyramid Matching (STPM) could also be researched on
and implemented for NDVI. |
