Image Manipulation using Quadtrees

Quadtrees simplify various image manipulation functions.This project contains various image manipulation functions like Compression of an .ppm Image(Binary File), Decompression, Image Rotations(Upside-Down, Flip, Left by 90 degrees, Right by 90 degrees), Image Filters(Gray, Sepia, Negative) and Union/Overlay of two Images. To know more, go through above presentation.

Run Locally

Clone the project

  git clone https://github.com/Anvita0305/Image-Manipulation-Using-QuadTrees

Build

  make final

  For Compression(image to binary file):
  ./final -c threshold input.ppm output.out

  For Decompression:
  ./final -d input.out output.ppm

  For Rotations:

    a)Mirror Image
    ./final -r m threshold input.ppm output.ppm

    b)Water Image
    ./final -r w threshold input.ppm output.ppm

    c)Rotate Left by 90 degrees
    ./final -r l90 threshold input.ppm output.ppm

    d)Rotate Right by 90 degrees
    ./final -r r90 threshold input.ppm output.ppm

  For Converting an Image to Grayscale:
  ./final -g threshold input1.ppm input2.ppm output.ppm

  For Converting an Image to Negative:
  ./final -n threshold input1.ppm input2.ppm output.ppm

  For Converting an Image to Sepia:
  ./final -s threshold input1.ppm input2.ppm output.ppm

  For Union of two Images:
  ./final -u threshold input1.ppm input2.ppm output.ppm
