/**
|
||
|
|
* latch Class for computing the LATCH descriptor.
|
||
|
|
* If you find this code useful, please add a reference to the following paper in your work:
|
||
|
|
* Gil Levi and Tal Hassner, "LATCH: Learned Arrangements of Three Patch Codes", arXiv preprint arXiv:1501.03719, 15 Jan. 2015
|
||
|
|
*
|
||
|
|
* LATCH is a binary descriptor based on learned comparisons of triplets of image patches.
|
||
|
|
*
|
||
|
|
* bytes is the size of the descriptor - can be 64, 32, 16, 8, 4, 2 or 1
|
||
|
|
* rotationInvariance - whether or not the descriptor should compansate for orientation changes.
|
||
|
|
* half_ssd_size - the size of half of the mini-patches size. For example, if we would like to compare triplets of patches of size 7x7x
|
||
|
|
* then the half_ssd_size should be (7-1)/2 = 3.
|
||
|
|
* sigma - sigma value for GaussianBlur smoothing of the source image. Source image will be used without smoothing in case sigma value is 0.
|
||
|
|
*
|
||
|
|
* Note: the descriptor can be coupled with any keypoint extractor. The only demand is that if you use set rotationInvariance = True then
|
||
|
|
* you will have to use an extractor which estimates the patch orientation (in degrees). Examples for such extractors are ORB and SIFT.
|
||
|
|
*
|
||
|
|
* Note: a complete example can be found under /samples/cpp/tutorial_code/xfeatures2D/latch_match.cpp
