Abstract:
We propose a method to restore colonoscopy videos that
have low quality RGB images. The main problem concerns
a time delay occurring in between the recordings of the R,
G and B colour channels. As the camera is moving along in
the colon, sometimes quickly, the resulting images show non
properly matched R, G and B causing blurry effects that impede
the medical doctors or computer-aided analysis methods.
We proposed to restore this artefact by first equalizing
the colour channels and then performing a robust camera
motion estimation and compensation. Experimental results
show significant improvements from the original videos.
