HistogramInterpolationMethod

Description

Possible values of HistogramInterpolationMethod:

Values of this enumeration:

  • Linear - Linear interpolation between consecutive bins of the histogram. Results in pixel-precise feature extraction.
  • Quadratic3 - Interpolation that fits a parabola to 3 consecutive bins. Allows subpixel feature extraction - with precision up to 1/6 px.
  • Quadratic4 - Interpolation that fits a parabola to 4 consecutive bins. Allows subpixel feature extraction - with precision up to 1/23 px for gaussian edges and infinite precision for ideal step edges. It is worse than Quadratic_3 only if several edges occur close to each other - with distances less than 3 pixels.
