Interpolation functions

group NVCV_CPP_CUDATOOLS_INTERPOLATION

Functions

template<NVCVInterpolationType I, int Position = 1, typename IndexType = int64_t> inline constexpr IndexType __host__ __device__ GetIndexForInterpolation (float c)

Function to get an integer index from a float coordinate for interpolation purpose.

Template Parameters

  • I – Interpolation type, one of NVCVInterpolationType.

  • Position – Interpolation position, 1 for the first index and 2 for the second index.

  • IndexType – Type of the returned value

Parameters

c – [in] Coordinate in floating-point to convert to index in integer.

Returns

Index in integer suitable for interpolation computation.
