Image Processing Tool

• This is a Python application that lets you open .pgm image files and edit them.
• Edits include contrast manipulation, filtering and thresholding functions (mainly grayscale processing)
• You can also add random noise and generate an ascii art from you image (find it in output folder)
• To execute it, run the image_processing_tool.bat file.

Interface

• It's made with python tkinter
• Images and histograms are shown using matplotlib.Figure.
• The image statistics are automatically calculated after each operation.
• When you choose manual transformation in the contrast menu, a new window will appear that will allow you to add points to the transformation graph and visiualise it.
