The effects of the median filter with different window sizes for ultrasound image
(Institute of Electrical and Electronics Engineers Inc., 2017)
Ultrasound is widely used in medical imaging. Unfortunately, speckle noise decreases the quality of the ultrasound image. One of the filters to reduce speckle noise in ultrasound image is the median filter. The median ...
Wide bandwidth absorption in the MWIR region using a thin and simple metamaterial absorber
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of ...
