Scene text erasing, which replaces regions with reasonable content in natural images, has drawn significant attention the computer vision community recent years. There are two potential subtasks scene erasing: detection and image inpainting. Both require considerable data to achieve better performance; however, lack of a large-scale real-world scene-text removal dataset does not allow existing methods realize their potential. To compensate for pairwise data, we made use synthetic after...
Scene-text image synthesis techniques that aim to naturally compose text instances on background scene images are very appealing for training deep neural networks due their ability provide accurate and comprehensive annotation information. Prior studies have explored generating synthetic two-dimensional three-dimensional surfaces using rules derived from real-world observations. Some of these proposed scene-text through learning; however, owing the absence a suitable dataset, unsupervised...
In this study, the dynamic deflections and vibrations of a belt conveyor system operating in ironworks are observed using high-speed telephoto mirror-drive active vision that can simultaneously switch viewpoints capture magnified images at rate hundreds frames per second (fps). The captures 160 fps pan-and-tilt scan mechanism. captured as multiple high-frame-rate video images. small vibrations, belts pillars, which have peak frequencies 10 Hz or more estimated with precision dozens...
In this study, dynamic deflections and vibrations of belt conveyors operating in ironworks are observed using a high-speed telephoto mirror-drive active vision that can simultaneously switch viewpoints capture zooming-in images at hundreds frames per second. 160-fps video for conveyor captured by our system with pan-and-tilt scan as multiple high-frame-rate the experiments, small belts pillars, whose peak frequencies 10 Hz or more, estimated precision dozens micrometers image analysis such...
Background and objective: High-resolution radiographic images play a pivotal role in the early diagnosis treatment of skeletal muscle-related diseases. It is promising to enhance image quality by introducing single-image super-resolution (SISR) model into radiology field. However, conventional pipeline, which can learn mixed mapping between SR denoising from color space inter-pixel patterns, poses particular challenge for with limited pattern features. To address this issue, paper introduces...
