An improved 2D optical flow sensor for motion segmentation [PDF]
, 2002 A functional focal-plane implementation of a 2D optical flow system is presented that detects an preserves motion discontinuities. The system is composed of two different network layers of analog computational units arranged in a retinotopical order.

Convective regularization for optical flow
, 2015 We argue that the time derivative in a fixed coordinate frame may not be the most appropriate measure of time regularity of an optical flow field. Instead, for a given velocity field $v$ we consider the convective acceleration $v_t + \nabla v v$ which ...

Optimal Filter Estimation for Lucas-Kanade Optical Flow
Sensors, 2012 Optical flow algorithms offer a way to estimate motion from a sequence of images. The computation of optical flow plays a key-role in several computer vision applications, including motion detection and segmentation, frame interpolation, three ...

Registration of Consecutive Frames From Wireless Capsule Endoscopy for 3D Motion Estimation
IEEE Access, 2021 Wireless Capsule Endoscopy (WCE) is a non-invasive medical procedure devised for painless in vivo inspection of the gastrointestinal (GI) tract. It is especially valuable for the examination of the small intestine since it is difficult to reach by ...

Integrated 2-D Optical Flow Sensor [PDF]
, 2004 I present a new focal-plane analog VLSI sensor that estimates optical flow in two visual dimensions. The chip significantly improves previous approaches both with respect to the applied model of optical flow estimation as well as the actual hardware ...

OptiFlex: Multi-Frame Animal Pose Estimation Combining Deep Learning With Optical Flow
Frontiers in Cellular Neuroscience, 2021 Animal pose estimation tools based on deep learning have greatly improved animal behaviour quantification. These tools perform pose estimation on individual video frames, but do not account for variability of animal body shape in their prediction and ...

DDFlow: Learning Optical Flow with Unlabeled Data Distillation
, 2019 We present DDFlow, a data distillation approach to learning optical flow estimation from unlabeled data. The approach distills reliable predictions from a teacher network, and uses these predictions as annotations to guide a student network to learn ...

Computation of Smooth Optical Flow in a Feedback Connected Analog Network [PDF]
, 1998 In 1986, Tanner and Mead \cite{Tanner_Mead86} implemented an interesting constraint satisfaction circuit for global motion sensing in aVLSI. We report here a new and improved aVLSI implementation that provides smooth optical flow as well as global motion
