Abstract Existing unsupervised visual odometry (VO) methods either match pairwise images or integrate the temporal information using recurrent neural networks over a long sequence of images. They are either not accurate, time-consuming in training or error accumulative. In this paper, we propose a method consisting of two camera pose estimators that deal with the information from pairwise images and a short sequence of images, respectively. For image sequences, a transformer-like structure is adopted to build a geometry model over a local temporal window, referred to as transformer-based auxi...
Existing approaches for SAR image registration focus on the global transformation correction between SAR images. However, there are often local deformations between images. Due to the time-changing viewpoint of video SAR, the images suffer a lot from local deformations, which can result in false alarms in moving target detection. This article presents an unsupervised image registration approach for the use of video SAR moving target detection, which has good registration performance and acceptable processing efficiency. The designed unsupervised learning-based framework is a cascade of two con...
JEMIMA KELLY The Pulitzer Prize-winning journalist Glenn Greenwald, one of Substack’s biggest names, makes between $80,000 and $160,000 a month in subscriptions to his newsletter. … Substack, a newsletter platform whose model is based on paid subscriptions, is flying particularly high. It announced on Tuesday that it was raising a further $65m from investors, in a round led by Silicon Valley VC firm Andreessen Horowitz that will reportedly value it at $650m. Established in 2017, Substack now has more than half a million subscribers — double what it had in December. And some of its bigge...
