v0.9 [May 5, 2022]
- The previous version of Tonfotos’ facial recognition system performed well on adult faces, but had great difficulty with children’s and infants’ faces. In the new version, the clustering algorithm has been completely redesigned. In addition to the fast algorithm that was used earlier, another one was added, which is noticeably slower, but much more accurate. In addition, the new algorithm uses the date the photo was taken as a feature, which greatly simplifies the task of identifying babies. Now Tonfotos combines the work of both algorithms. If for a person in the library there are still few examples of faces for training, a fast algorithm will be used, with which the user can quickly collect the necessary database of faces to train a more accurate algorithm. After that, the system switches to a more accurate one. The results of the test show that now photos of children are classified as well as photos of adults. In addition, the algorithm copes much better with difficult cases - when the face is only partially visible, or when the person is photographed in profile, or even does not look into the frame at all. And also in low light conditions and low image resolution. As a result of the application of the new algorithm, the proportion of photographs of people that will be classified in semi-automatic mode has increased significantly, and now they are in a significant majority.
- Also made a number of minor fixes and improvements in the recognition function, largely due to user feedback.
