Speckle is a type of multiplicative noise degrading visual quality in imaging using optical coherence tomography (OCT) resulting in difficulty of assessment by experts. Thus speckle reduction algorithms are required for enhancing image quality of OCT and assisting in their visual assessment. The objective of this work is to evaluate the performance of speckle reduction algorithms using five image...
Synthetic aperture radar (SAR) images provide scattering information which can be used under any weather conditions for glacier monitoring. Our purpose is to estimate a displacement field characterizing at each position the local speeds and orientations of the glacier displacement. Recent proposed methods build a vector field by tracking patches between two SAR images co-registered on static areas...
In this paper, we develop a novel method for forest biomass estimation. The intensity values of Advanced Land Observation Satellite-Advanced Visible and Near Infrared Radiometer type 2 and PRISM images and the texture features of the Japanese Earth Resources Satellite 1 image are used in a multilayer perceptron neural network (MLPNN) that relates them to the forest variable measurements on the ground...
