Talita Perciano is a Research Scientist at Lawrence Berkeley National Laboratory, and a Computer Vision consultant for the National Energy Research Scientific Computing Center (NERSC). She is also part of the Image Analysis team of the Center of Applied Mathematics for Energy Related Applications (CAMERA). Her current knowledge is image processing and pattern recognition applied to different image data, allied to HPC. Relevant research includes: filamentous structures segmentation and quantification using Markov Random Fields (2D ocular fundus photography, plant roots in soil profile images, roads/rivers in satellite images), brain imaging (CT, MRI), vibro-acoustography image formation and restoration, among others. She has been working on computer vision algorithms and statistical computing the past 10 years, and she is a developer of R packages, a software environment for statistical computing and graphics, for image processing and analysis. She earned her doctorate in Computer Science from the University of São Paulo in 2012.
