Stable stitching method for stereoscopic panoramic video
CAAI Transactions on Intelligence Technology, 2018 This paper proposes a stable method of generating a stereoscopic panoramic video with the omnidirectional stereo (ODS) format. Different from the traditional image stitching method which can only be applied to generate a monocular panorama, we adopt an ...

Recognising facial expressions in video sequences [PDF]
, 2008 We introduce a system that processes a sequence of images of a front-facing human face and recognises a set of facial expressions. We use an efficient appearance-based face tracker to locate the face in the image sequence and estimate the deformation of ...

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

Learning the representation of instrument images in laparoscopy videos
Healthcare Technology Letters, 2019 Automatic recognition of instruments in laparoscopy videos poses many challenges that need to be addressed, like identifying multiple instruments appearing in various representations and in different lighting conditions, which in turn may be occluded by ...

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-

Application research on improved CGAN in image raindrop removal
The Journal of Engineering, 2019 Rainy weather can greatly reduce the image quality and hinder the subsequent processing of the image. In order to achieve raindrop removal on rainy images, the single image raindrop removal method based on conditional generative adversarial networks ...
