Impulse noise is the most common noise present in digital images. Removal of impulse noise from the images is a difficult task in image processing. Impulse noise occurs in images during the process of image transmission and image acquisition. Many noise removal techniques have been proposed, each having its own respective advantages and disadvantages. These noise removal techniques must be desi...

many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...

Removal of motion artifacts is a critical challenge, especially in wearable electroencephalography (EEG) and photoplethysmography (PPG) devices that are exposed to daily movements. Recently, the significance artifact removal techniques has increased since EEG-based brain–computer interfaces (BCI) healthcare usage PPG were spotlighted. In this article, development on EEG sensor systems introduce...

Background: The aim of this study was to evaluate functional outcome and complications with a long term followup (minimum of 2 years post-operative) in patients with mid-shaft clavicle fractures treated with precontoured lockingplates.Methods: We included 41 patients. Goniometric measurement of shoulder range of motion (ROM) was performed,as well as functional evaluation using the rating scale ...

INTRODUCTION A late-developing infection after an uneventful initial spinal instrumentation procedure is rare. Delayed infection and new fistula formation have been reported from a few months to 13 years. Here we report an unusual 17-year-delayed fistula formation after primary spinal instrumentation. The patient underwent hardware removal surgery with antibiotic therapy as a definitive treatme...

The isoelastic ultrahigh-molecular-weight polyethylene tension band may be considered an alternative to stainless steel wire for tension band fixation of olecranon fractures. In this article, we present our technique using this isoelastic tension band and describe the outcomes of 7 patients who underwent open reduction and internal fixation of closed, displaced olecranon fractures with minimal ...

UNLABELLED The purpose of this study was to investigate the influence of plate location during ulna shortening osteotomy on the incidence of hardware irritation and clinical outcome. METHODS Forty patients (17 women, 23 men; mean age, 47 years) who underwent a shortening osteotomy of the ulna due to idiopathic ulna impaction syndrome were examined after a mean of 36 months. All complications ...

BACKGROUND Fixation of the greater trochanter with total hip replacement is challenging and associated with short- and long-term complications. Locking plate technology has been used for fixation of other bones and may be applied successfully in trochanteric fixation. The purpose of this retrospective study was to analyze the utility of the use of trochanteric locking plates in total hip arthro...
