Free form deformation algorithm

WebMar 9, 2024 · Specifically, our data augmentation algorithm includes a B-spline free form deformation method to randomly distort the strokes of characters but maintain the overall structures. We generate 20–40 augmented images for each training data and use this augmented training set to train a deep neural network model in a standard pipeline. WebGround deformation contains important information that can be exploited to look into the dynamics of a geothermal system. In recent years, InSAR has manifested its strong power in the monitoring of ground deformation. In this paper, a multi-temporal InSAR algorithm, WLS InSAR, is employed to monitor and characterize the Yangbajing geothermal field in …
