Imagetools is a school project made atPolytech Paris Sud. It is develop withC langage.

This project can manipulateBMP andPGM pictures.

• 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

Imagetools have 3 interfaces :

• Console interface
• Commande line interface
• Graphical interface

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

Launch :./imagetools-ci.out

Launch./imagetools-cli.out

• 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

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

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

Launch./imagetools-gui.out
