Multiresolution Analysis of Sar Images
SAR images have shown to be of high complexity and to require dedicated processing techniques. This paper presents two applications of the wavelet and multiresolution theory to the enhancement and characterization of SAR data. The rst application describes an improved method for speckle reduction. The second method uses a fractal-based texture measure to provide elements for SAR image segmentat...

15 صفحه اولImproving the visualisation of polarimetric response in SAR imagery - from pixels to images
1 Presented at IGARSS 2002, Toronto, 2002. This work was partially supported by NSF (CCR-0086065). Abstract— This paper presents a new method for the visualisation of polarimetric response patterns on a synoptic basis. The aim of this approach is to synthesise traditional polarimetric response graphs with the spatial overview provided by standard remote sensing image processing techniques. By d...
متن کاملSegmenting Sky Pixels in Images
Outdoor scene parsing models are often trained on ideal datasets and produce quality results. However, this leads to a discrepancy when applied to the real world. The quality of scene parsing, particularly sky classification, decreases in night time images, images involving varying weather conditions, and scene changes due to seasonal weather. This project focuses on approaching these challenge...
متن کاملImages as Bags of Pixels
We propose modeling images and related visual objects as bags of pixels or sets of vectors. For instance, gray scale images are modeled as a collection or bag of (X,Y, I) pixel vectors. This representation implies a permutational invariance over the bag of pixels which is naturally handled by endowing each image with a permutation matrix. Each matrix permits the image to span a manifold of mult...
