imagetools

Imagetools is a school project made at Polytech Paris Sud. It is develop with C langage.

This project can manipulate BMP and PGM pictures.

Features

  • Read a picture
  • Save a picture
  • Set filters
    • Reversed
    • Horizontal rotation
    • Vertical rotation
    • Linear filtering
      • FIR 1D horizontal
      • FIR 1D vertical
      • FIR 2D with matrix convolution
        • FIR 2D border x
        • FIR 2D border y
        • Sobel filter
  • Get histogram
    • With only intensity
    • With all component (only for BMP)
  • Save histogram
  • Set histogram equalisation

Interfaces

Imagetools have 3 interfaces :

  • Console interface
  • Commande line interface
  • Graphical interface

Compilation

To compile the whole project : make

If you only want one interface :

  • Console interface : make ci
  • Command line interface : make cli
  • Graphical interface : make gui

Use

CI : Console interface

Launch : ./imagetools-ci.out

CLI : Command line interface

Launch ./imagetools-cli.out

Command's list

  • Open an image (-p for pgm and -b for bmp)
  • Set a filter
    • --gray
    • --reversed
    • --h-rotate
    • --v-rotate
    • --fir1d-h (+ int_depth)
    • --fir1d-v (+ int_depth)
    • --fir2d-x
    • --fir2d-y
    • --sobel
    • --equalize-hist
  • Get histogram (--histogram + r,g,b,i or c + path)
  • Save image (-s path)

Each command will be apply in the order which they are passed

Examples

We get lena.ascii.pgm, and we set the reversed filter, we save the intensity histogram and save the new picture as reversed/lena.ascii.pgm

./imagetools -p img/lena.ascii.pgm --reversed --histogram i histogram/lena.ascii.pgm -s reversed/lena.ascii.pgm

GUI : Graphical interface

Launch ./imagetools-gui.out
