Hi everyone,

I am using EyesWeb 5.3.0 and I was able to draw trajectories using the video Micro-dance with the block Geometric Trajectory from points_2. I wanted to compute some trajectory features using TrajectoryAnalysis blocks but I am not being able to do that since I get an error saying that the input I am using is not considered a trajectory. Do you have any idea of how can I compute these features (such as acceleration, velocity, direction etc)? If you have any example patch it would be ideal :)

I also need to find the best way of storing these features in text files.

Many thanks!

Hi, the attached patches show how to make a simple analysis of a trajectory, save it to file, and playback the saved data synchronized with the original video.

Thank you very much for your answer! I tried to run the patch Trajectories Analysis and for some reason I get an error saying that the item specified was not found in the collection and also " Class identifier (ClassID) of the searched item was "geometric_labelled_set_2d_double".

Do you have any idea why this may have happened?

Best wishes,

Inês Vigário

Sorry, I used a newer version of EyesWeb to edit the patch.

Attached is the patch for EyesWeb 5.3.0
