Instrument Tracking via Online Learning in Retinal Microsurgery [chapter]

Yeqing Li, Chen Chen, Xiaolei Huang, Junzhou Huang
2014 Lecture Notes in Computer Science  
The performance of the proposed method has been evaluated on a fully annotated dataset of retinal instruments in in-vivo retinal microsurgery and on a laparoscopy image sequence.  ...  To address these problems, we propose a new approach for robust instrument tracking.  ...  The variance filter can be evaluated efficiently by using integral images [14] . The second stage is random ferns (forest) [15] on patches for comparing the pixel values.  ...

2016 Computational and Mathematical Methods in Medicine  
For the same reason, frequent failures in tracking add the overhead of reinitialization of the tracking.  ...  Our approach models the instrument as a Conditional Random Field (CRF) where each part of the instrument is detected separately.  ...  Color, location, and gradient-based features have been associated with the landmarks for training random ferns.  ...
