A novel hybrid filter for image despeckling based on improved adaptive wiener filter, bilateral filter and wavelet filter

H Salehi, J Vahidi - International Journal of Image and Graphics, 2021 - World Scientific
Images are widely used in engineering. But, some images such as medical ultrasound
images are mainly degraded by an intrinsic noise called speckle. Therefore, de-speckling is …
