I was in Beijing for International Geosicence and Remote Sensing Symposium (IGARSS) 2016, held in National Convention Center. I have presented my paper robust nonlinear unmixing of hyperspectral images with a linear-mixture/nonlinear fluctuation model is scheduled as oral presentation on 15th July. During these occasion I have also had nice chat with Jocelyn Chanossot, Chein-I Chang, Antonio Plaza.
