I will post the bird stamps inherited from both fathers in chronological order. Today's stamp is the International Letter Writing Week stamp issued on October 7, 1974. The design is pine tree and a hawk painted by Shukei Sesson. The original painting is stored by Tokyo National Museum.
Yesterday's 293 starlings were counted manually, but since we live in an age where AI is being touted as taking away people's jobs, I decided to try automating the count. First, I tried using an app called CountThings. The results are below.
If the template is Bar-tailed Godwits: 76 birds (correct rate 26%, incorrect rate 0%, miss rate 74%)
If the template is Insects (Aphelinidae): 232 birds (it cannot be used because the same bird is counted double or triple)
Image of count result: See below
Conclusion: Cannot be used as is. If a template for the starling can be created, the accuracy may be improved a little more.
It seems that some bird researchers are thinking about similar ideas, and we can expect more useful tools in the future. In a limited application such as counting geese using a drone, results have already been achieved in which the error is within ±15%.
