2013-11-21 22:28:51 -0600 | answered a question | How to build opencv_world in 2.4.7? looks like you need the zlib library - I haven't installed it but a good place to start would be to head to their site and follow their instructions. Best of Luck! |

2013-08-03 19:40:32 -0600 | commented answer | How to read/write a PCA object from/to a cv::FileStorage ? Agreed, otherwise the above posted solution by Mostafa is what I do |
2013-08-03 19:39:23 -0600 | commented answer | FileStorage: can write but can't read Size, Rect, etc. Yeah I usually do something like this too - however I wonder if this could be done cleanly? The problem is also there for cv::Vec I think, maybe we should open a ticket? |

2012-10-29 17:16:56 -0600 | asked a question | Webcam Select Timeout error on Linux Hello, after running standard opencv video capture code for several seconds I receive an error that says: select timeout and the program freezes. I've followed standard build procedures, has anyone else encountered this error before? Thanks! |
2012-10-26 14:00:12 -0600 | asked a question | Webcam capture freezes after a few seconds in Ubuntu Hello, I am having an issue capturing from a webcam using OpenCV, the capture starts and works fine but then freezes after a few seconds. Here is the code I was running: I have tried on a few different computers and the same problem happens. It also happens when I try and view the webcam using cheese. I must be doing something wrong (is this a v4l issue?), I've followed standard OpenCV build tutorials and I've had this issue since at least 2.4.1. I'd like to get this issue fixed has anyone else had an issue like this? |

2012-09-12 14:59:29 -0600 | asked a question | OpenCV and Point Grey Grasshopper Issues Hello, We're having issues with capturing images from our Point Grey Grasshopper camera. The camera returns images fine but if an image is not captured for a while then the image that gets returns is not the latest image but an image from a while ago in between the last capture and the current time. Anyone else encountered this? |
2012-08-17 15:07:19 -0600 | asked a question | cv::FileStorage for custom Types Problem Hello, I am trying to write code allowing me to cleanly use opencv FileStorage with classes I have built - I have done this before with success but this time it is not working and I don't know why, plus the compiler error output is strange. Here is a code snip that is what I am trying to do: The only thing that is different from when I have done this before is the use of a base class and the fact that I have the code for the saving and loading in the header. I tried moving the static void write and read to the cpp but I get the same error. The error I get is: no matching function for call to 'write(cv::FileStorage&, std::sting&, const Alg_Params&)' but the weird part it I also get this warning 'write(cv::FileStorage&, std::sting&, const Alg_Params&)' defined but not used [-Wunsed-function] This doesn't make sense it should see this function way before it needs it. I am building using Qt Creator on Linux. Thanks for the help! |
