hello - no prob. |
|
drats - ulong should be size_t for other platforms - working... |

Fix for /issues/278 - core dump in the case of no match(...) results.
|
As far as I can see, the fix is merged and this can be closed down. |
|
Yes. Let me put a reference of it here for the record #279 |
|
👍 then you can also close it down :P |
|
I would if I could :) @vpisarev please assist us by closing this issue |

fixes fixed compile error and warning Remove AGAST (for merger to upstream opencv) wrapping remaining xfeature2d classes to scripting added test for http://code.opencv.org/issues/3943; replaced "const InputArray" with "InputArray" to avoid warnings about "const const _InputArray&" added test for http://code.opencv.org/issues/3943; replaced "const InputArray" with "InputArray" to avoid warnings about "const const _InputArray&" adding LATCH fixed warnings in LATCH fixed errors fixed warnings fixed warnings2 fixed warnings3 fixed warnings4 fixed warnings5 added description of LATCH and fixed indentation cleaned the code a bit added tests and renamed LATCH Code to grab the red lined polygon from Google Maps added python support and completed documentation figure update added stdout welcome message and fixed warning fixed warning text enhancement trying to fix python wrapper warning on win64 trying to solve pyhton warnings bugfix4269 included remarks in http://answers.opencv.org/question/59293/problem-with-example-motemplcpp/ Replace tab with four space Add rotation invariance option for BRIEF descriptor. Fix docs and repush for buildbot. Bug fix for feature extraction According to CartToPolar() function documentation, result angles could be in range (0..360). To prevent index overflow this check is important. Adding edge-aware disparity filtering Added basic interface and demo for disparity filtering, added unoptimized fast weighted least squares filter implementation. Current demo tests domain transform, guided and weighted least squares filters on a dataset, measures speed and quality. Fix for Bug 4074. This seems to be just a typo-error, because the Tesseract API can handle correctly with RGB images (double-checked and it works). Fix for Bug opencv#3633: do away with "quads [2][3] = 255;" The four lowest bits in each quads[i][j] correspond to the 2x2 binary patterns Q_1, Q_2, Q_3 in the NM paper [1] (see in page 4 at the end of first column). Q_1 and Q_2 have four patterns, while Q_3 has only two. added INRIA pedestrian dataset autowbGrayworld: include+src+test+testdata+sample Add saturation based thresholding to grayworld WB Add basic perf tests for grayworld Add more doxygen comments Suppress uchar conv related warning on Windows Apply fixes suggested by Vadim Be more correct with int types Remove dangling N_good++ Use cvRound to suppress Windows warnings remove floor call vs2010 does not know, ceil, floor, round and friends. also, those are plain integer divisions, that do not need floor at all. New stereo module created and added some relevant files for this module Update README.md made some extra changes to the modules so I receive no warnings moved the opencv2/core/private.hpp from stereo_binary_sgbm.cpp to precomp.hpp fix for issue opencv#195 avoid overflow in histogram access SurfaceMatching: OpenMP indices Fixes compiler error: "index variable in OpenMP 'for' statement must have signed integral type" Adding confidence support and optimizing disparity filtering DisparityWLSFilter demonstrated the best results, so I removed all the other filters. Quality was significantly improved by adding confidence support to the filter (left-right consistency + penalty for areas near depth discontinuities). Filter was optimized using parallel_for_ and HAL intrinsics. Demo application was rewritten for better compliance with OpenCV standards. Added accuracy and performance tests. Documentation was added, as well as references to the original papers. added PASCAL VOC dataset + add KCF Tracker, initial commit, added: tutorial, trackerKCF.cpp, modified: tracker.cpp, tracker.hpp adding the resize feature References for KCF tracker and KCF-CN tracker Unified the formatting Fixed: ROI extraction when the given ROI is out of image; made the max_patch_size to be adjustable; add the CN feature extraction method Removing all shadowing variables, make functions to const, make the table of color-names become static change the color-names table to const Add a framework for choosing the descriptor Added error message for descriptor other than GRAY Added new line at end of file Fixing the ColorNames table initialization Fixed warning: conversion from double to int Updated the support for color-names features and fixing some typos Fixing the tabulation Split the training coefficient into numerator and denumerator Added the feature compression method Fixing some indentations Fixing some indentations Fixing alignments Fixing some alignments Use Doxigen format Remove whitespaces Removing whitespaces in featureColorName.cpp Add an example code for the KCF tracker update the header in example/kcf.cpp Updating the rectangle drawing, avoid warning from variable conversion Added doxygen documentations Fixing warnings remove warnings Fixing some warnings TLD Fixes & Optimizations 1. TLD now have module structure 2. Made some small code optimizations 3. Fixed Ensemble Classifier according to the original paper - 10 randomized ferns 4. Added comments to most of the functions and methods Added test on TLD Dataset Added BSD-compatible license Added BSD-compatible license to some files Fixed header Fixed build error Fix Fix opencv#2 Fix opencv#3 Fix opencv#4 Fixed Warnings opencv#1 Fixed Warnings opencv#2 Fixed Warnings opencv#3 Shadow Fix Fixing whitespaces Fixing whitespaces opencv#2 Fixing whitespaces opencv#3 Adds a first implementation of the OCRBeamSearchDecoder class using the Single Layer CNN character classifier described in Coates, Adam, et al. paper: Text detection and character recognition in scene images with unsupervised feature learning, ICDAR 2011 Add a demo program for the OCRBeamSearchDecoder class and needed data files trailing whitespaces fix compilation warnings fix win64 compilation error: arrays must be defined with compile-time fixed size :) fix doxygen warnings Fix for opencv#278 - core dump in the case of no match results. Modified reported poses by constraining to the number of poses found. ulong -> size_t fixed warnings in the tracking module Added OCL versions of Sr and Sc functions 2-nd level of parallelization + detector remake 1. Added 2-nd level of parallelization of NN on OpenCL 2. Restructured detector - now all filters work independently: Variance Filter->Ensemble->NN, through "buffers" Warnings Fix opencv#1 Fixing Warnings opencv#2 Fixing Warnings opencv#3 Fixing Warnings opencv#4 Fixing Warnings opencv#5 Fixing Warnings opencv#3 Fixing Warnings opencv#4 Fixing Warnings opencv#5 Added OCL version of "integrateAdditional" function Whitespace Fix Transparent API Support Fixing Warnings Fixed bug in LSDDetector where mask doesn't remove all undesired lines Fixing GCC 4.9 warning Fix memory leak bug #4420 Fix bug #4373: Error (Assertion failed in resize) when passing very elongated contours to the recognition module make sources compile again on MSVC 2012 (VC 11) by adding round() fix suffix that was in-compatible with MSVC 2012 (VC 11) eliminate some warnings use better condition for checking if compiler supports round() fixing facerecognizer tutorials and interface Adds createOCRHMMTransitionsTable() utility function to create a tailored language model transitions table from a given list of words (lexicon) update to use the new createOCRHMMTransitionsTable() function, and fix program description in header comments fix Winx64 warnings Better CNN model for character recognition. Trained with an augmented dataset by adding translation/scale variations. Updated the croped word recognition with new class numbering (compatible with previous NM classifier). Overload the run() method in BaseOCR class in order to adapt to different classifier callbacks. The original run() method accepts only one Mat input image, this is expected to be a binarzed image with black and white text and works both with the OCRTesseract class and the OCRHMMDecoder class when the character classifier callback works with binary images (e.g. NM). The new run() method accepts two Mat input parameters. One for the gray scale (or color) source image and the other for a binary mask where each connected component corresponds to a pre-segmented character in the input image. This way the OCRHMMDecoder is able to work with character classifiers that operate in grey scale (or color) images (e.g. a CNN). Adds example on segmented word recognition. Shows the use of the OCRHMMDecoder with the NM and CNN default classifiers. Minor bugfix: removes unwanted space character at the begining of recognition output strings. Fix w64 warnings Fix w64 warnings Improving DisparityWLSFilter interface and adding a tutorial Now the filter natively supports StereoBM and StereoSGBM with no parameter tuning required. Also, now user won't need to set the ROI and the right matcher parameters manually, it is all done in the respective convenience factory method based on the left matcher instance. Tutorial was added to clarify the provided example of use. doc update

A trivial problem - but one none-the-less (leading to unnecessary time spent) is that the result vector resulting from the match method on PPF3Detector may be of length(size) 0. This possibility is not taken into account in the sample code that follows.
I'll fork, fix, and, create a pull request.
