Orientation tracking algorithm

[bruno-f-cruz]

Currently, we are using an algorithm identical to the one previously suggested by Goncalo.

Since the lab already appeared to have a better working solution it would be good to have access to that piece of code and try to implement it in the current workflow.

I am summarizing here the orientation tracking algorithm.

1st: check the major axis orientation vs the previous orientation. if it is flipped, correct it to follow the same direction as the previous tracking point. 2nd: check the cosine similarity between the orientation vector (centroid to head) and the motion vector (centroid to previous centroids). if cosine similarity > 0 then we save a 1 into an array. if cosine similarity < 0 then we save a -1 into an array. if the motion vector is smaller then a threshold, we save a 0 into an array. 3rd: Sum the array over a specific amount of frames (last 9 frames). if the sum of the array is < 0, then it flips the orientation vector and resets all the array values to 0 to reset the algorithm.

Could you show me how to implement a similar algorithm or an alternative that does the same calculations in bonsai.

Tell me if there are any questions?

Could you place here the bonsai code that was done by gonçalo during the last bonsaiclub where this issue was addressed?
