From April 2009 until September 2010, I worked under supervision of Professor Ricardo de Queiroz, co-oriented by Professor Díbio Leandro Borges and Professor Camilo Chang Dorea, on the study of color constancy and calibration between color devices using a commercial camera as calibrative device. I also implemented an image scene classification (indoor vs outdoor) algorithm using machine learning. The results were presented at 7th DF’s Scientific Initiation Congress and at the Workshop de Pós-graduação do CIC (UnB).
