Preserving invaluable historic recordings has drawn some interest because the traditional record playback system wears out the record gradually. This paper presents a non-contact method to reproduce sound signal from gramophone records using 3D scene reconstruction of the micro-grooves cast on a record surface. Because of the unique shape of the(More)
Preserving historic recording on gramophone records is an important task because the traditional record play back system damages/wears out records eventually. We present an optical flow based method to reproduce the sound signal from gramophone records using 3 D robust scene reconstruction of the surface orientation of the walls of the grooves. The imaging(More)
