Improved Freeman decomposition Gaussian Mixture Model Polarimetric SAR data Iteration desorientation EM algorithm Unsupervised classification
2016/11/23
Due to the increasing volume of available SAR Data, powerful classification processings are needed to interpret the images. GMM (Gaussian Mixture Model) is widely used to model distributions. In most ...
Illumination Decomposition for Material Recoloring with Consistent Interreflections
Illumination Decomposition Consistent Interreflections
2016/5/24
Changing the color of an object is a basic image editing operation,
but a high quality result must also preserve natural shading. A common
approach is to first compute reflectance and illumination i...
