Originally, he made fine-tuning within the range of 20%. However, as more and more fingerprints were excluded, by the time of the third 150 fingerprints, the matching fingerprints given by the system were already very exaggerated. Many fingerprints were detected by human eyes. Looking at it, it looks completely irrelevant—the fingerprints after two deformations can't be expected to be sorted accurately by the system, otherwise, Jiang Yuan wouldn't need to sort 150 fingerprints.

But at this time, Jiang Yuan thought of other colleagues.

They must also know how to fine-tune. Moreover, in terms of patience, the policemen who do fingerprint posts are not weak. What is it to look at fingerprints for several hours? Experts can see hundreds of thousands of fingerprints, and it is normal to see thousands of fingerprints for one case.
