Pyramidal Refinement of Lucas Kanade Optical Flow based Tracking of Peripheral Air Embolism in OCT Contrast Imaging
International Journal of Computer Applications
Air embolism often causes severe consequences in patients, in which several cases need fast treatment at the earlier stage. This paper proposes a computerized approach for detection as well as estimation of motion trajectory of air emboli using OCT contrast imaging technique. Due to change in optical properties, speckle pattern changes from fluid to air bubble and so does the speckle pattern on the image plane. This phenomenon helps to track the air bubble due to change in brightness patterndoi:10.5120/8252-1777 fatcat:yq3meqwjqvctnkuyhtkzb4yqby
