how to test with my camera?

Exception of type InvalidArgument encountered while initializing the input pipeline: InputBase :: Image sequence folder ../../../Datasets/CMT/sylvester does not exist

Set img_source to u for USB camera and f for firewire camera.

If you want to test on a dataset sequence (like sylvester from CMT as in your cfg file), set db_root_path to the folder containing the dataset files.

hope to any suggestions!

There seems to be something wrong with either your OpenCV installation or the v4l2 driver used for accessing USB cameras. To check if the driver is OK, you can install visp and change pipeline to v to use the visp pipeline instead.

This page addresses the same error as yours so might help you fix v4l2 issues in OpenCV.

why? show a window with title: "Please select the object to track by clicking at its four corners" but when i click, no response and print select timeout

[abhineet123]

Are you sure the camera is working correctly and actually capturing images because the window in the screenshot seems blank ? Also, I can see a lot of output in the terminal that should not be there. Did you add these for debugging ?

I have never seen the "select timeout" before nor is there any code within MTF that would print it, so this too seems something to do with compatibility issues between OpenCV and your camera.

Refer these for possible causes of the select timeout: http://answers.opencv.org/question/120525/opencv-select-timeout-at-high-resolutions/ https://stackoverflow.com/questions/12715209/select-timeout-error-in-ubuntu-opencv?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa
