Journal ArticleDOI
Multiscale MAP filtering of SAR images
TL;DR: The resulting filter combines the classical adaptive approach with wavelet decomposition where the local variance of high-frequency images is used in order to segment and filter wavelet coefficients.
Journal ArticleDOI
Convolutional Neural Networks for the Automatic Identification of Plant Diseases.
TL;DR: This work surveys 19 studies that relied on CNNs to automatically identify crop diseases, describing their profiles, their main implementation aspects and their performance, and provides guidelines to improve the use of CNNs in operational contexts.
Journal ArticleDOI
Analysis, Evaluation, and Comparison of Polarimetric SAR Speckle Filtering Techniques
TL;DR: Results show that filters performances need to be assessed using a complete set of indicators, including distributed scatterer parameters, radiometric parameters, and spatial information preservation.
Proceedings ArticleDOI
Multi- spectral image resolution refinement using stationary wavelet transform
TL;DR: A pixel-level fusion method to refine the resolution of a multi-spectral image using a high-resolution panchromatic image using the ARSIS method which takes into account the higher-order statistical moments of the wavelet coefficients and allow processing of non-dyadic images.
Proceedings ArticleDOI
SAR Image Filtering Via Learned Dictionaries and Sparse Representations
TL;DR: This work proposes a novel approach for speckle noise reduction in SAR images using a sparse and redundant representation over trained dictionaries called K-SVD, effective in removing white additive Gaussian noise.
