Aplha mask and compositing tool


To build a tool which lets one alpha mask a green screen image composite that image with a background.


openimageio library was used to input, display and write images. Various keyboard presses enable different operations like writing, moving back and forth between images and so on. Alpha masking was first done using binary mask and an advanced greyscale mask was tried.

The petro vlahos algorithm and spill suppression extensions were successfully implemented. The alpha masked image was composited onto a background.


Some of the images generated using the tool,

Dr. Malloy, always smiling
Dr Davis on planet X001
Dr. Duchowski on Mars


Planning a project in stages. Have a plan B because plan A will never work out.


The satisfaction one gets when the hard-work one puts in, pays off.
