Correlation Image Sensor-Assisted Single-Frame Optical Flow Estimation in Motion-Blurred Scenes
Single-frame optical flow estimation is a more challenging task than predicting the optical flow between adjacent frames in a video. This paper presents a two-stream network that combines motion information from correlation images with appearance ...

Deep HDR Deghosting by Motion-Attention Fusion Network
Multi-exposure image fusion (MEF) methods for high dynamic range (HDR) imaging suffer from ghosting artifacts when dealing with moving objects in dynamic scenes. The state-of-the-art methods use optical flow to align low dynamic range (LDR) images before

MULTI-ORIENTATION EDGE-BASED SATELLITE IMAGE MATCHING METHOD FOR OPTICAL AND SAR IMAGES [PDF]
Multi-sensor image matching is a key technology to fully exploit complementary information on images from multiple sources. In particular, the nonlinear radiance distortion between optical and SAR images makes image matching very difficult.

Correlation Image Sensor for Algebraic Solution of Optical Flow
In this article, we describe several enhancements of a three-phase correlation image sensor (3PCIS) toward its uses for a direct algebraic method of optical flow detection, i.e., determining velocity field of image patterns for detecting, tracking, and ...
