Today, the accuracy of face expression recognition (FER) algorithms is very low, and it does not go only for our products since it is a general tendency connected with the technological capacity of these algorithms. Given that this technology does not work accurately enough, these projects don't come into wide use on an industrial level, because the cost of development and operation is high, and the results are relatively low. Our solutions do have emotion recognition as a feature. However, we would like to emphasize that there are no flawless algorithms for emotion detection, and we would not like to misinform either our partners or our clients. We recommend implementing tried-and-true technologies that are sure to bring the expected results immediately.
