EasyImage::ProfileDerivative

Computes the first derivative of a profile extracted from a gray-level image.

Namespace: Euresys::Open_eVision

[C++]

void ProfileDerivative(
EBW8Vector* sourceVector,
EBW8Vector* destinationVector
)

void ProfileDerivative(
EBW16Vector* sourceVector,
EBW16Vector* destinationVector
)

Parameters

sourceVector

Pointer to the source vector.

destinationVector

Pointer to the destination vector.

Remarks

Taking the derivative transforms transitions (edges) into peaks.

Note. Since the EBW8 data type only handles unsigned values, the derivative is shifted up by 128. Values under [above] 128 correspond to negative [positive] derivative (decreasing [increasing] slope).
