There are three types of interpolation provided by our platform:
Most popular type is Linear value interpolation.
Annotations are made by marking the coordinates of exposed marker points, such as the vertices of a Bounding Box frame. As the object moves, its marker points change position, which is observed in subsequent frames. To reduce the operator's time, an interpolation function (Linear value interpolation) is used to automatically calculate the location of points on intermediate frames based on two fixed positions on key frames.
The chart shows the calculated coordinates of Bounding Box placement, which will be located on the conditional line between the annotated frames on keyframes. If the scene change is due to the camera position change, the operator needs to correct the position of marker points on the intermediate frames.

Flat value interpolation is the most basic form of interpolation, where the values between two known points are assumed to be equal to one of those points. This method is used when there is no need for more accurate smoothing or approximation of the data.
No value interpolation. If you select this interpolation type for the class shape, the object mask will only be present on the keyframe and will not exist in all other non-keyframes.
