Faster gradient descent and the efficient recovery of images
, 2013 Much recent attention has been devoted to gradient descent algorithms where the steepest descent step size is replaced by a similar one from a previous iteration or gets updated only once every second step, thus forming a {\em faster gradient descent ...

Earth and Space Science, Volume 12, Issue 12, December 2025.Abstract X‐band Phased array radars are characterized by high spatial and temporal resolution, but suffer from a range of data quality problems, such as echo voids after the filtering of ground clutter, abnormal radials, radial obstructions and irregular missing radar echoes. This paper proposes a radar echo image restoration model (GCD) based on color

Medical Physics, Volume 52, Issue 10, October 2025.Abstract Background Cone beam computed tomography (CBCT) plays a crucial role in verifying patient positioning during radiotherapy. However, CBCT images are often blurred by motion originating from breathing, bowel motion, and/or repositioning. Conventional methods often employ gating techniques to mitigate motion artifacts by assuming periodicity ...
