2017-04-16 19:09:51 -0600 | commented question | Object tracking while moving After a lot of investigation and some try-outs I found that TLD may be the best option to track objects in moving images, but my main problem remains how to detect movement in the video that is not part of the regular camera movement. Any suggestions? |
2017-04-09 16:47:04 -0600 | commented answer | Object tracking while moving Hi Manuvision, Many thanks for your suggestion. I indeed found this example earlier this week and tried to get it working on Friday. It failed with the message "cannot open file 'opencv_imgcodees320d.lib'". What I thought to be a simple thing of locating the correct library and add it to the project was far from it. I don't seem to be able to locate the file anywhere. Do you know where to find it? Many thanks! |
2017-04-08 17:47:26 -0600 | asked a question | Object tracking while moving Hi, I am looking for a starting point to track moving objects in a video, while the camera is also moving itself. Similar to a car that is driving and detects movement but filters out his own flow/background. I find quite some examples of motion detection and tracking, but for some reason there are a lot of video examples available on tracking moving objects while also the camera is moving, but none share the code. From my research I understand that I should use flow control a possible solution, but I am to new in OpenCV and while like to have some code example to start with. Anyone know a project with code that uses the technique? Thank you! |

2017-03-30 02:11:46 -0600 | answered a question | detect road shape on image without lanes lines Hi, I am still trying to find an approach to solve this issue. Base on a document I found about road edge detection in infrared images, it was suggested to down sample the image using the grassian pyramid technique and detect the convergence common point on the horizon with hough lines. As expected there will be an adaptive threshold as the vehicale is moving. Is someone having an example of these techniques? Or maybe is aware of a project that does exactly this? It appears to be a technique that is used in the automotive industry to detect pedestrians as they are suppose to be on the road sides. My additional issue is that I am a VB .NET developper and the conversion from C++ is not an easy one. Thank you! |

2017-03-24 23:31:28 -0600 | asked a question | detect road shape on image without lanes lines Hi, I am trying to find a way to detect the shape of the road surface. I have experimented a lot with the examples on lane detection, but the issue is that the contrast of the concrete surface and road sides (often grass) is not enough especially when there are no side lines as you have in lanes. A good example is the image below. It uses background abstraction to find the car, but I actually need to road surface shape (preferably without the lighter gray side ways) also without having painted lane lines like your normally have. docs.opencv.org/master/Background_Subtraction_Tutorial_Result_2.png Many thanks |
