Question 2. (1 point) Biovision BVH is a very popular file format for storing human body motion data. Learn this file format by yourself from online resources, then 1) describe it in a short paragraph. 2) How can you use its data to compare the similarity between two body poses?
1) The BVH file format was originally developed by Biovision, a mobile hosting services company, as a way to provide capture information to their customers. The term BVH stands for Biovision sequence data. This format mainly replaces the previous format they developed, the BVA format discussed in the next section, as a way to provide bone detail with the addition of motion data. The BVH format is an excellent all-encompassing format, whose only problem is the lack of a complete description of the base of the pose (this format has only descriptive descriptions of children's parts from their parent, no rotating offset description), and has no explicit details on how to draw parts but that doesn't affect in the description of the proposal.
2) There are a total of two methods through which we can use it's data to compare the similarity between two body poses:
The three angles included in the points between - 1 and 1 are the
following equation:
The part represents the points of the category, and
the main points mean the similarity of the abetter. The chances of
getting a negative side are slim due to the limitations of the
human body.
:
Similarity points for root frames that can be obtained by adding
∆θx, ∆θy, and ∆θz. If the points are large, the difference between
the two root systems is small.
