2013-10-24 11:43:01 -0600 | asked a question | How to do multiple detect using CamShift in OpenCv? I am working on a project it is actually originated from the camshift demo and i really wanted to track in a multiple manner. It is done by color matching. I also modified the demo, i added sounding an alarm and a allowable motion for the tracked object. here is the a part of the code that i added to the demo: ` What i wanted to happen is to trigger the alarm when another object that is of the same color is present, but i dont know how. Can anyone help how to do multi detect? |

I would like to know where I can find links that leads to camshift with kalman filter tutorials or examples that might give a hint to creating my own. Please help. |
2013-08-29 05:35:51 -0600 | commented answer | Error loading xml file. @Siegfried, I have executed the example on the link you gave, but this time the error is stating "Native' has exited with code -1 (0xffffffff)". This is the error upon running the example. The problem is similar but this time, the error message did not show up instead it automatically terminates the project. Also when I execute the .exe it runs and produces output similar to the links example. |
2013-08-28 21:38:24 -0600 | commented answer | Error loading xml file. I have actually placed or stored all the necessary files in the the folder where the project is created. The xml is placed together within the projects folder. I have followed a certain tutorial I found in the internet and somehow i can't identify the problem. I even tested the xml's that came pre-installed in the opencv, but still it can't load the xml. If you could share some links on how to fix this or other examples where I can test it, please let me know. |
