We present a new edge detector for automatic extraction of oceanographic (mesoscale) features present in in-frared (IR) images obtained from the Advanced Very High Resolution Radiometer (AVHRR). Conventional edge detectors are very sensitive to edge fine structure, which makes it difficult to distinguish the weak gradients that are useful in this(More)
BACKGROUND Inflammatory markers (IM) are elevated in atrial fibrillation (AF). However the relation of IM to substrate modificationinAF remains unclear.We sought to assess the relationship of IM to fractio ated atrial electrogram (FAE) in patients undergoing AF ablation. METHODS At baseline, left atrial (LA) pressure was recorded and peripheral blood was(More)
