چکیده

Optical and electronic crosstalk in the Focal Plane Assemblies (FPAs) of satellite instruments degrades the radiometric quality of remote sensing data, and can be a major limitation to achieve performance quality needed for environmental and climate monitoring research. Correction algorithms for this effect have been developed, such as the one developed for MODIS short wave infrared (SWIR) bands using lunar data [1]. However, the crosstalk effect is a complex problem, and needs to be tested and corrected during the instrument design phase.

The Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology)

Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of speckle noise. In this study we use a new ensemble framework which is a combination of several Multi-Layer Perceptron (MLP) neural networks to denoise OCT images. The noise is...
