Education
PhD in Electrical Engineering (2020)
- Institution: Faculty of Physical Sciences and Mathematics, University of Chile
- Thesis: Color–Texture Pattern Classification Using Global–Local Feature Extraction, an SVM Classifier, with Bagging Ensemble Post-Processing
- Description:
This research proposed a novel approach to classification problems using color and texture features, highlighting the importance of multiscale feature extraction to integrate color and texture information effectively. The results led to two publications: a conference article and a journal article.
Diploma of Technology in Electrophysiology (2019)
- Institution: Faculty of Medicine, University of Chile
- Description:
Specialized in bioelectric signal processing and electrophysiology of sensory systems. Final work involved a theoretical analysis of an electrophysiological signal for clinical use and a proposal for clinical application.
Electrical Engineering (2010)
- Institution: Faculty of Physical Sciences and Mathematics, University of Chile
- Thesis: Molds design for iris detection through Particle Swarm Optimization
- Description:
Proposed two methodologies to create templates for iris localization: a handcrafted approach and an automated method using Particle Swarm Optimization (PSO). The PSO method generates templates independent of anthropometric data and captures key eye features for improved iris detection accuracy.
