Due to the coherent processing of synthetic aperture radar (SAR) systems, multiplicative speckle noise arises providing a granular appearance in SAR images. This kind of noise makes it difficult to analyse and interpret Earth surface images. Therefore, the search for new techniques to mitigate the speckle is a constant task in the image processing literature. Current state-of-the-art filters in remote sensing area explore the philosophy of similarity between patches (neighborhoods). This thesis aims to expand a recently proposed filtering algorithm:the Non-Local Means (NLM), which represents a new paradigm for filtering images, and analyses and compares its capacity of speckle reduction in intensity SAR images, technique known in the...
