2017-01-24 06:24:56 -0600 | asked a question | Real-Time Multi-Object Tracking with Learning My Goal is to have real-time MultiTracker with Learning. I tried KCF, MIL e.t.c they are not realtime. can you recommend any realtime learning mecahnism or ways to improve above proposed one. |
2017-01-06 04:05:13 -0600 | commented question | Build OpenCV with OpenCL support Thank you. I tried test opencl code and it gave excellent results. Can you please explain this line in testOCL_OCV32.cpp. I understood that m is the average time taken, but sqrt(v) has +/- what does the value indicate and why v is required? |
2017-01-03 04:13:09 -0600 | commented question | Build OpenCV with OpenCL support Thanks for your reply. I am using the latest version of OpenCV from github. I am using face_detection sample code and replaced Mat with UMat.The breakpoint at this line is triggered. but retval is 0. I tried on both AMD processor + Carrizo also on Intel processor + Nvidea Graphics in windows 10 and windows 7. No performance improvement anywhere. How did you get nvcompiler.dll ? I installed AMD-APP-SDK like said in question above, but that didn't help me. also tried installing Intel OpenCL SDK & INtel OpenCL Runtimes..No luck with that as well. |
2017-01-01 05:48:05 -0600 | asked a question | Build OpenCV with OpenCL support in CMake, I built OpenCV with OpenCL Enable ON(It automatically detected the When i make use of I downloaded AMD-APP-SDK from this link and tried to build but there was no OpenCL binaries (instead i saw opengl dll files[glew32.dll & glut32.dll]. How do i build OpenCV with OpenCL by linking the OPENCL_LIBRARY? |

2016-11-25 07:20:56 -0600 | asked a question | opencv_ffmpeg module crash (IP Camera) I'm using IP webcam android app(It converts mobile camera into IP web camera). Getting below error. If the internet connection is slow or if the Wi-Fi is disconnected in my android device the program crashes
even if the code is wrapped within try catch block, it crashes! |
2016-11-24 01:05:09 -0600 | asked a question | CMake error while building MultiTarget-tracker library. I'm trying to build Multitarget-tracker using CMake in windows. Initially i had the warning below,
I manually pointed out the directory of build version of OpenCV library and tried to build. I referred this link while building. Warning:
I checked the OpenCV_FOUND, but after i press 'configure' again, it automatically unchecks. |

2016-11-11 22:38:47 -0600 | asked a question | Getting status of multiple objects. I tried the tracker algorithms (MIL,BOOSTING,MEDIANFLOW,TLD and KCF) , apart from KCF the rest of the algorithms are very slow while tracking objects. Which is the best algorithm for tracking multiple objects? I tried camshift as well, if we move the object is out of the frame, camshift still tracks(marks) somewhere within the frame. How to get the status of the tracker in Camshift or in any other algorithm. My Goal is to track multiple objects also check if object present within the frame. |

2016-09-28 00:37:04 -0600 | asked a question | How to convert SFML image to OpenCV Mat in c++? Below code is used to convert an OpenCV Mat image into SFML image. How to convert SFML image back to Mat image? If texture or sprite can't be converted to OpenCV Mat,then is it possible to convert sf::Image to OpenGL and convert it back to cv::Mat Update: I referred this post, but still was not able to convert. It crashes at below line of code (when i display image ) |
