The original Otsu's method is logically correct, however, the float precision issue is fatal during the subtraction if the intra-group means are approximately equal, which will fail in Miri test. That's why an equivalent formula was introduced.
For details, please refer to the documentation (already in Katex format).
The contribution document also be modified to mention the necessity of Miri.
