High-resolution urban aerosol monitoring using Sentinel -2 satellite images (University of Tehran, 2019-06-01)Satellite remote sensing aerosol monitoring products are readily available but limited to regional and global scales due to low spatial resolutions making them unsuitable for city-level monitoring. Freely available satellite ...

Application of Local Supervised Feature Selection Approach to Target Detection in Hyperspectral Imagery (University of Tehran, 2019-06-01)Feature selection (FS) for target detection (TD) attempts to select features that enhance the discrimination between the target and the image background. Moreover, TD usually suffers from background interference. Therefore, ...

Handling ill-posedness and overparameterization of rational function model using Bi-objective particle swarm optimization (University of Tehran, 2019-06-01)The existence of both ill-posedness and overparameterization phenomena in the rational function model (RFM), makes it difficult to determine rational polynomial coefficients (RPCs). In this regard, Meta-heuristic algorithms ...
