Door state detector

Videoanalytics module detecting the state of the door: open or closed. The module had to work on doors of different types, including glass and sliding doors, as well as to react to half-open doors and ignore people and other objects partially overlapping the doorway.

To solve the problem we used a monocular MiDaS depth detector. It was used to analyze the depth changes on the edges of the doorway.

Document edge detector

Boundary recognition of certain types of documents: passports, ID card, ticket ...

It was required to define clear document boundaries, assuming that each boundary can be defined by a straight line. That is the document is described by 4 points instead of 2 as with the normal detection. The problem was solved by segmenting the photo and then post-processing it.
The model was ported from Pytorch to C++ to run in the product environment.
