This extended abstract is for the “Audio Melody Extraction” contest of MIREX2009. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on temp...

This extended abstract is for the “Audio Melody Extraction” evaluation in MIREX2010. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement.

PURPOSE The deformable registration of pulmonary computed tomography images before and after radiation therapy is challenging due to anatomic changes from radiation fibrosis. We hypothesize that a line-enhanced registration algorithm can reduce landmark error over the entire lung, including the irradiated regions, when compared to an intensity-based deformable registration algorithm.
