Image denoising is the process to remove the noise from the image naturally corrupted by
the noise. The wavelet method is one among various methods for recovering infinite …

Magnetic resonance (MR) images are often contaminated by Gaussian noise, an electronic
noise caused by the random thermal motion of electronic components, which reduces the …

The directional characteristic of the low-frequency and high-frequency coefficients based on
the wavelet transform for original images is discussed and analyzed, and a novel image …

Several image denoising algorithms are developed so far to obtain a better denoised sensor
images. But they fail to preserve the edges of the images. In order to overcome this, an …

Medical images like X-ray, computed tomography, ultrasound, and magnetic resonance
imaging (MRI) are produced using different techniques; during this process, noise is added …

With the gradual maturity of computer vision technology, using intersection surveillance
videos for vehicle trajectory extraction has become a popular method to analyze vehicle …

Aiming at the strong spot noise caused by the reflection of meat slices in fish image with
foreign matters that collected by ordinary camera or Single Lens Reflex (SLR) camera, we …

The insulation pull rod is the main transmission mechanism of the circuit breaker. In addition
to strong electrical performance, it should also have strong mechanical properties. Studying …

Diabetic retinopathy (DR) causes vision loss insufficiency due to impediment rising from
high sugar level conditions disturbing the retina. The progression of DR occurs in the foveal …

This paper presents an analysis to image denoising using discrete wavelet transformation
(DWT) and complex wavelet transformation (CWT). The affect of image denoising on the …
