The body curvature comparison between wild-type zebrafish and transgenic zebrafish.

<p>(A) wild-type zebrafish; (B) transgenic zebrafish; (C) the comparison of curvatures measured along twenty body locations of wild-type zebrafish (green plot) and transgenic zebrafish (red plot), respectively. The fish body (blur curve) is characterized at twenty body locations (red dot) in (A) and (B). In (c), the x-axis represents the fish body location index, and the y-axis represents the body curvature value (in the unit of degree). Note that we extracted the skeleton of the fish body and used twenty control points to describe the posture of fish. These control points are uniformly distributed along the fish body skeleton from the head to the tail. The first point is located at fish head and the last point is located at fish tail. The body curvature is measured at each point location.
