Mobile application for norm control of cleaning

An algorithm was developed for comparing a cleaned room in a hotel with a reference image.
After cleaning the room, the maid takes a photo of the room and sends it to the server using a mobile application. The server receives the image, compares it with a pre-existing reference photo, and sends a response as a percentage match to the reference. Also, the response from the server comes with an image with places not matching the original photo highlighted in red. The results of cleanings and comparisons are accessible in the hotel admin panel.
The algorithm of this system allows to improve the quality of work and automate the process of monitoring the cleaning of rooms in hotels and simplify the workflow of hotel managers.
