Test for Pull Request # 3829
|
|
https://github.com/Itseez/opencv/pull/3829
|
|
|
|
This test code creates brute force matcher for accuracy of reference, and the test target matcher.
|
|
Then, add() and train() transformed query image descriptors, and some outlier images descriptors to both matchers.
|
|
Then, compared with the query image by match() and findHomography() to detect outlier and calculate accuracy.
|
|
And each drawMatches() images are saved, if SAVE_DRAW_MATCHES_IMAGES is true.
|
|
Finally, compare accuracies between the brute force matcher and the test target matcher.
|
|
|
|
The lsh algorithm uses std::random_shuffle in lsh_index.h to make the random indexes table.
|
|
So, in relation to default random seed value of the execution environment or by using "srand(time(0)) function",
|
|
the match time and accuracy of the match results are different, each time the code ran.
|
|
And the match time becomes late in relation to the number of the hash collision times.
|
