“…The median filter is among the most widely used nonlinear spatial domain filters. In 2010 the scientist Yen suggested the use of ultrasound enhancement method by employing the dual tree wavelet method [10]. Ultrasound scanning is highly open to human error while measuring size of organs and tissues because of noisy US images and inexperienced sonographers.…”

Ultrasound imaging helps the doctor to view the tissues and organs in the body's abdominal area with no ionization risks compared to other internal organ examination methods dependent on radiation. It offers highly precise renal imaging of suspected acute kidney diseases. This paper proposes temporary filtering methods to improve ultrasound images from ultrasonic kidney video. The proposed filters focus on the detection and diagnosis of kidney disease by processing consecutive images of the acquired kidney video. Extending the spatial median image filters to temporal dimensions after the picture frames are manually clipped and aligned in MATLAB by image processing Toolbox to suppress speckle noise, and enhance a doctor's diagnostic information quality.
