An unsupervised optical flow estimation for lidar image sequences
, 2021 In recent years, the LiDAR images, as a 2D compact representation of 3D LiDAR point clouds, are widely applied in various tasks, e.g., 3D semantic segmentation, LiDAR point cloud compression (PCC). Among these works, the optical flow estimation for LiDAR

Imaging Sequences for Hyperpolarized Solids [PDF]
Molecules, 2020 Hyperpolarization is one of the approaches to enhance Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) signal by increasing the population difference between the nuclear spin states. Imaging hyperpolarized solids opens up extensive possibilities, yet is challenging to perform.

Laryngoscopic Image Stitching for View Enhancement and Documentation - First Experiences [PDF]
, 2012 One known problem within laryngoscopy is the spatially limited view onto the hypopharynx and the larynx through the endoscope. To examine the complete larynx and hypopharynx, the laryngoscope can be rotated about its main axis, and hence the physician ...

Adaptive Vector Quantization for Lossy Compression of Image Sequences
Algorithms, 2017 In this work, we present a scheme for the lossy compression of image sequences, based on the Adaptive Vector Quantization (AVQ) algorithm. The AVQ algorithm is a lossy compression algorithm for grayscale images, which processes the input data in a single-

Visual inference of flow flux via free surface PDE model and image sequence assimilation
IET Cyber-systems and Robotics, 2019 The free-surface flows, such as flows in rivers, lakes, and tides, play an important role in hydraulic engineering and environmental monitoring. However, due to their complex and changeable characters, the precise evolution procedure is quite difficult ...
