Medical image enhancement using threshold decomposition driven adaptive morphological filter [PDF]
, 2008 One of the most common degradations in medical images is their poor contrast quality. This suggests the use of contrast enhancement methods as an attempt to modify the intensity distribution of the image.

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Designing the fast filter bank with a minimum complexity criterion
, 2004 The fast filter bank (FFB) is an extremely efficient single-rate filter bank due to the sparse population of non-zero coefficients in the subfilters. Its subfilters are designed and operated based on the frequency response masking (FRM) technique.

Design of a Multilayer Dual-Band Balanced Bandpass Filter on a Circular Patch Resonator
Frontiers in Physics, 2021 This letter presents a novel multilayer dual-band balanced bandpass filter (BPF) design by using two perturbed circular patch resonators. The TM11 mode and TM21 mode of the resonator with odd-symmetric field distributions are explored to realize the ...
