Class DeblurHorizHalftone

java.lang.Object
  jjil.core.PipelineStage
      jjil.algorithm.DeblurHorizHalftone

public class DeblurHorizHalftone
extends PipelineStage

Uses deconvolution to remove blur from a Gray8Image. The blur removed is a horizontal Gaussian blur with a given standard deviation. The background noise level in the input image can be adjusted. The output Gray8Image is rescaled so the maximum and minimum values fill the range from Byte.MIN_VALUE to Byte.MAX_VALUE.
