Several OCR projects were reviewed for their suitability against a set of criterias: Most important was the ability of the OCR solution to integrate with popular app development frameworks and their availability for, at least, the Android operating system. Additionally, the solution should support saving a frame from the video stream as an image file, should run on-device instead of the cloud and should minimally be free to use. Finally, it should be able to analyze every frame of the video rapidly to enable fast digitisation of the values on the balance's display. These criteria were successfully fulfilled by our chosen solution: ML-Kit API ().
