Color Layout Descriptor CLD - related to jpeg/mpeg...
|
|
Different scanning methods.. Zigzag scanning? Might matter!
|
|
Median descriptor -> Pearson code? up/down -> Local average
|
|
Color Histogram information ... Binning.. derived code
|
|
Invariance - some SIFT derived descriptor?
|
|
Combined descriptors
|
|
|
|
Experiments
|
|
-Clear goals! -> finding near copies. dont expect too much.
|
|
-Big test! automated
|
|
-Finding near copies
|
|
-Transformations per image (scaling, cropping, text, rotation, noise, contrast, brightness, JPEG compression)
|
|
-Combinations of transformations
|
|
-Modify images -> test for invariance
|
|
-Keyword matching unlikely to work
