1
Infrared thermography (IRT) measures brain surface temperature, revealing physiological and pathological processes during neurosurgery.
-
2
Motion artifacts significantly hinder IRT applications by disrupting the spatiotemporal correspondence essential for accurate temperature gradient analysis.
-
3
Existing motion correction techniques for IRT include cepstrum-based methods, phase correlation, and optical flow, each with varying effectiveness and limitations.
-
4
The proposed Bispline registration technique offers a fast, robust motion correction solution using bilinear interpolation without requiring multimodal imaging.
-
5
This method minimizes least squares error while ensuring physically plausible motion vector fields, preserving the contiguous nature of brain tissue.
