- Abstract summary: We propose 4D-temporal deep learning for end-to-end motion forecasting and estimation using a stream of OCT volumes.
Our best performing 4D method achieves motion forecasting with an overall average correlation of 97.41%, while also improving motion estimation performance by a factor of 2.5 compared to a previous 3D approach.

- Abstract: Forecasting motion of a specific target object is a common problem for
surgical interventions, e.g. for localization of a target region, guidance for
surgical interventions, or motion compensation. Optical coherence tomography
(OCT) is an imaging modality with a high spatial and temporal resolution.
Recently, deep learning methods have shown promising performance for OCT-based
motion estimation based on two volumetric images. We extend this approach and
investigate whether using a time series of volumes enables motion forecasting.
We propose 4D spatio-temporal deep learning for end-to-end motion forecasting
and estimation using a stream of OCT volumes. We design and evaluate five
different 3D and 4D deep learning methods using a tissue data set. Our best
performing 4D method achieves motion forecasting with an overall average
correlation coefficient of 97.41%, while also improving motion estimation
performance by a factor of 2.5 compared to a previous 3D approach.

This work presents a novel framework that can effectively learn a compact and compositional representation for dynamic human.
A simple yet effective linear motion model is proposed to provide a rough and regularized motion estimation.
Experiments demonstrate our method is not only efficacy in recovering dynamic human with accurate motion and detailed geometry, but also amenable to various 4D human related tasks.

We provide a novel motion estimation framework of Dense-Sparse-Dense (DSD), which comprises two stages.
In the first stage, we process the raw dense image to extract sparse landmarks to represent the target organ anatomical topology.
In the second stage, we derive the sparse motion displacement from the extracted sparse landmarks of two images of different time points.

We propose a Modified Pseudo-3D Feature Pyramid Network (MP3D FPN) to efficiently extract 3D context enhanced 2D features for universal lesion detection in CT slices.
