Image enhancement using warping technique
Electronics Letters, 2003 An image enhancement algorithm based on a warping technique is presented. The warping map is chosen in order to sharpen the edges of the image. In contrast to other algorithms, enhancement is performed without introducing overshoot in sharp edges and without amplifying the noise present in the original image.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
