Underwater No-Reference Image Quality Assessment for Display Module of ROV

Figure 7

Qualitative analysis on the influence of simplification on . (a) Seven common colors. (b) of different colors in different water bodies. (c) of different colors under different cameras. We simplify the types of water into three. It can be seen from (b) that the calculation error of yellow water caused by simplification is larger than that of blue and green water body caused by simplification. The yellow water body in the underwater image is not common, so the simplification of water body type is applicable to most occasions.
