InterpolationMethod
Defines the interpolation method used by a function.
Elements
Name | Value | Description |
---|---|---|
IMAQ_ZERO_ORDER | 0 | The function uses an interpolation method that interpolates new pixel values using the nearest valid neighboring pixel. |
IMAQ_BILINEAR | 1 | The function uses an interpolation method that interpolates new pixel values using a bidirectional average of the neighboring pixels. |
IMAQ_QUADRATIC | 2 | The function uses an interpolation method that interpolates new pixel values using a quadratic approximating polynomial. |
IMAQ_CUBIC_SPLINE | 3 | The function uses an interpolation method that interpolates new pixel values by fitting them to a cubic spline curve, where the curve is based on known pixel values from the image. |
IMAQ_BILINEAR_FIXED | 4 | The function uses an interpolation method that interpolates new pixel values using a bidirectional average of the neighboring pixels. The function makes the averaging calculations using fixed-point mathematics, which increases the performance of the interpolation but reduces the accuracy. |
