Some cases of grass carp where the scale shape is cross-shaped and the scale is in the fish picture


Correct case

  • Measuring scale shape is cross-shaped.
  • Light-coloring and single shooting background.
  • Try to keep the fish straight and not twisted.
  • The fish body and measuring scale should be complete and not overlapping.
  • The length of the fish body should not exceed 75% of the length of the picture.
  • The file name should consist entirely of English alphabets and numbers.

Wrong case

  • There is overlap between the fish body and label, which leads to unrecognizability.

Wrong case

  • The fish body is twisted, which leads to unrecognizability.

Wrong case

  • The fish body is distorted and not the side of the fish body, which leads to unrecognizability.

Wrong case

  • The proportion of fish body in picture is too large, which leads to unrecognizability.
  • If your image isn't recognized for this reason, you can manually add a border and recognize it again. As shown in the picture on the right.

Correct case
