Olexa Bilaniuk	5748cea80d	Removed unnecessary precision in damped Cholesky decomposition. Cholesky decomposition is stable; It is not necessary to carry it out internally at double precision if the result will be truncated to single precision when stored.	10 years ago
Vladislav Vinogradov	44e41baffe	use new functions before all tegra:: calls	10 years ago
Dmitry-Me	2311504c44	Reduce variables scope	10 years ago
Mansour Moufid	b7be49426d	Cast some image coordinates and sizes to double.	10 years ago
Olexa Bilaniuk	f454929d9c	PRNG changes: xorshift128+ algorithm, and seeding API. - Switched to the extremely fast, while simple and high-quality, xorshift128+ PRNG algorithm by Sebastiano Vigna in "Further scramblings of Marsaglia's xorshift generators. CoRR, abs/1402.6246, 2014" (2^128-1 period, passes BigCrush tests). Performance improved by 10% over random(). - Added an API to allow seeding with a specified seed, rather than using rand() or random(). This allows deterministic, reproducible results in tests using our algorithm (although findHomography() does not yet support passing an entropy source on its own end).	10 years ago

ASUS	6dbf13d7b5	saveBestModel() is modified. accuracy test is passed.	10 years ago
Olexa Bilaniuk	ff2509af56	Fixed printouts in testcase to blame the correct method for a failure. Previously, certain test failures by the method RHO would result in an error blaming RANSAC instead. The fix involves a parameter change to several functions in test_homography.cpp.	10 years ago
Dmitry-Me	c3f8fc41b7	Parameters should have been passed by reference	10 years ago
Olexa Bilaniuk	ccd33a721e	Fixed build failures related to designSPRTTest().	10 years ago
Olexa Bilaniuk	adac8c04bb	Converted to C++ style, + bugfixes. The code has been refactored in response to feedback on Pull Request Also, outputZeroH() now also zeroes the inlier set, much like outputModel().	10 years ago
Olexa Bilaniuk	87c2b8197a	Bug fixes in mask output. Previously, the output mask of inliers could remain completely uninitialized. This fix is the first part of a solution.	10 years ago
Olexa Bilaniuk	b90800f0c7	Corrected typo in comment. The inverted JtJ does not multiply itself, but rather Jte. Correct this in the comment.	10 years ago
Olexa Bilaniuk	2609e77af7	Silence spurious loss-of-data warnings from Windows. Added explicit casts to silence warnings in fundam.cpp and rhorefc.cpp.	10 years ago
Olexa Bilaniuk	ce0570b777	Splitting vectorized code into separate branch. Deleted SSE code from master branch. Slight cleanups in fundam.cpp were made as a consequence.	10 years ago
Olexa Bilaniuk	69b146412a	Edited Doxygen documentation in the module calib3d. Added a mention within calib3d.hpp that the flag RHO is available as an option on calls to findHomography().	10 years ago
Olexa Bilaniuk	02124f19e6	Further LevMarq improvements. Implemented a damping-parameter choice strategy similar to that described in http://www2.imm.dtu.dk/documents/ftp/tr99/tr05_99.pdf. Removed a few debug statements. Chosen a new starting lambda value, 0.01. We now actually output the mask of inliers.	10 years ago
Olexa Bilaniuk	ff91af825d	LevMarq made semi-functional. Replaced the complex rules OpenCV uses to select lambda with a naive but fast heuristic. It's imperfect but produces good results. It is still subject to the same problem as OpenCV - namely, on occasion LevMarq will make a poor result even worse.	10 years ago
Vijay Pradeep	1292fdf71a	Now using default arg instead of overloads	10 years ago
Olexa Bilaniuk	4401095b38	Optimizations to Jacobian and error calculations. Deleted multiplications by zero and consequent additions of zero terms.	10 years ago
Olexa Bilaniuk	7fca146b21	More LevMarq bugfixes. LevMarq now doesn't outright fail, but doesn't seem to improve things much if at all.	10 years ago
Olexa Bilaniuk	33a3fba2d1	Work on LevMarq code. Refactoring of Cholesky decomposition. Fix for memory corruption bug. LevMarq as a whole still non-functional.	10 years ago

Olexa Bilaniuk	68e59d6154	[RHO] Initial commit of RHO algorithm for rapid homography estimation. Implements the RHO algorithm as presented in Paper: Bilaniuk, Olexa, Hamid Bazargani, and Robert Laganiere. "Fast Target Recognition on Mobile Devices: Revisiting Gaussian Elimination for the Estimation of Planar Homographies." In Computer Vision and Pattern Recognition Workshops (CVPRW), 2014 IEEE Conference on, pp. 119-125. IEEE, 2014. - Complete, heavily documented reference C implementation, as well as temporarily disabled dirty SSE2 port. - Enabled tests for RHO in test_homography; Currently these fail presumably due to too-stringent accuracy requirements. - Refinement and final refinement are not yet functional; Do not pass their corresponding flags to RHO.	10 years ago
