Class Subtraction

  • public class Subtraction
extends java.lang.Object
    Given two images of same dimension it'll apply subtraction operation on each pixel pair & return modified image

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      protected java.awt.Color[] extractRow​(int row, java.awt.image.BufferedImage img)
      Given a buffered image & row index, it'll extract out all pixel intensities present along that row
      protected boolean isEligible​(java.awt.image.BufferedImage operandOne, java.awt.image.BufferedImage operandTwo)
      Operand images on which we'll apply any arithmetic operation needs to be of same dimension
      java.awt.image.BufferedImage operate​(java.awt.image.BufferedImage operandOne, java.awt.image.BufferedImage operandTwo, boolean clip)
      Concurrently applies subtraction operator on two buffered images of same dimension, where each row gets processed in a different thread, making overall execution faster, leveraging power of multi threaded multicore CPUs
      java.awt.image.BufferedImage operate​(java.lang.String operandOne, java.lang.String operandTwo, boolean clip)
      Invokes previous implementation, after reading two operand images into buffered image object
