Despeckling of Images using Weiner Filter and Hybrid Median Filter
Images are a crucial part of everyone’s life in this modern world. The increase in the number of these has led to a need of better results like better quality, better diagnosis of medical problems etc. Reducing noise from the images is a challenge for the researchers in digital image processing. Several approaches are there for noise reduction. Generally speckle noise is commonly found in the s...
متن کاملA New Classification Approach for PolSAR Images
PolSAR images provide more information than the conventional radar images and so greatly improves the ability to terrain discrimination. This work is focused on the problem of the classification of different terrain types of PolSAR images. The proposed method uses a combination of two different classifiers. This method is named as Meta classifier and compared with other competitive classifiers....
متن کاملDespeckling of Ultrasound Medical Images: A Survey
Digital image acquisition and processing techniques plays important role in clinical diagnosis. Medical images are generally corrupted by noise during their acquisition and transmission. Removing noise from the original medical image is still a challenging problem for researchers. Ultrasound imaging is widely used for diagnosis over the other imaging modalities like Positron Emission Tomography...
متن کاملImproved adaptive complex diffusion despeckling filter.
Despeckling optical coherence tomograms from the human retina is a fundamental step to a better diagnosis or as a preprocessing stage for retinal layer segmentation. Both of these applications are particularly important in monitoring the progression of retinal disorders. In this study we propose a new formulation for a well-known nonlinear complex diffusion filter. A regularization factor is no...
متن کاملAn adaptive window hybrid median filter for despeckling of medical ultrasound images
Speckle is a random multiplicative noise which obscures the perception and extraction of fine details in ultrasound image and despeckling is necessary for better diagnosis. The main aim of despeckling is to keep the important features such as edges of the ultrasound image. In this paper an adaptive window hybrid median filter is proposed for despeckling of medical ultrasound images. In the prop...
