Description

Two variant of Binary threshold Implemented

  1. Simple Binary Threshold
    If the pixel value is more than the threshold then the pixel value is set to maximum or else to 0
  2. Inverse Binary Threshold
    If the pixel value is more than the threshold then the pixel value is set to 0 or else to maximum

Two Truncation threshold Implemented

  1. Threshold Truncate
    If the pixel value is more than the threshold then it is truncated if the direction specified is regular. If the direction is in inverse then values below the thresholds are truncated.
  2. Truncation to zero
    If the pixel value is less than the threshold then it is set to zero if the direction specified is regular. If the direction is in inverse then values above the thresholds are set to zero.
