An Evaluation of Image Feature Detectors Based on Spatial Density and Temporal Robustness in Microsurgical Image Processing

Optical image processing is part of many applications used for brain surgeries.Microscope camera, or patient movement, like brain-movement through the pulse or a change in the liquor, can cause the image processing to fail.One option to compensate movement is feature detection and spatial allocation.This allocation is based on image features.The frame wise pitchy delight onee stick matched features are used to calculate the transformation matrix.

The goal of this project was to evaluate different feature detectors based on spatial density and temporal robustness to reveal the most appropriate feature.The feature detectors included corner-, and blob-detectors and were applied on nine videos.These videos were taken during bosch 4100 table saw motor replacement brain surgery with surgical microscopes and include the RGB channels.The evaluation showed that each detector detected up to 10 features for nine frames.The feature detector KAZE resulted in being the best feature detector in both density and robustness.
