Bone length coherence represents how well the initial inter-articular length is maintained throughout the sequence. Near the maximum value, similar to the initial bone length, near the minimum value, different from the initial bone length. If bone length consistency is measured low, people may question the integrity of the data. 

To find the local maxima, we identify the ranges where the values reach a peak within the dataset. A local maximum is a point where the value is higher than its neighboring values. This indicates periods of high activity or dynamic movement. The detection is based on a threshold percentage (e.g., 80% of the maximum value) to focus on the most significant peaks. The output lists the frame ranges where these peaks occur and their respective values.
