Matrix code probability🔗

Calculates the probability that a matrix code is present in an image patch. For this, gray-level histogram is used.

Inputs🔗

  • image: Input image.

  • corner: Pixel coordinate of the upper left corner of the region of interest. A 1-by-2 matrix.

  • size: The size of the rectangle framing the region-of-interest. If size is undefined (either width or height is NAN), the histogram is computed from the whole image.

  • filterWindow: Window size for smoothing the histogram vector.

Outputs🔗

  • confidence: The probability (0-1) that the region-of-interest in image represents a matrix code (e.g. QR code or data matrix)
