Foreground estimation in dynamic background conditions

Dynamic background cancellation is a fundamental problem in video processing. Eventhough estimating the foreground is trivial in static background conditions, estimating the foreground can be tricky when the background is dynamic as well. In this project we try differrent approaches to detect the background and foreground in a video. We start with classical approaches and try to evaluate their pros and cons. Finally, we propose the most suitable combination of video processing operations to get the most accurate results.

Galvans - autonomous robots

Two robots (one stationary and one moving). Moving robot had capabilities to follow a line maze, identify coloured boxes and transmit the colour to the stationary bot that could shoot a ball to the colored target. The mobile bot could follow a wall as well.

8.

Theseus - autonomous robot

A robot that can find it’s way through a wall maze, pick up a coloured payload and deliver it along a path marked by the particular coloured arrow.
