Robust spectral analysis of videocapsule images acquired from celiac disease patients

<p>Abstract</p> <p>Background</p> <p>Dominant frequency (DF) analysis of videocapsule endoscopy images is a new method to detect small intestinal periodicities that may result from mechanical rhythms such as peristalsis. Longer periodicity is related to greater image texture at areas of villous atro...
