Luis A. Figueroa

Hello there! I'm a Research Engineer in the Research Engineering and Design Lab at Adobe Research. Previously, I was a GEM Full Fellow in the Biomedical Engineering Department at Carnegie Mellon University.

 

My main research interests are in computer vision, machine learning, and deep learning. I have broader interests in applied mathematics, cognitive science, health, and medicine.

 

I earned my BA in Computer Science and Mathematics from Occidental College where I was advised by Dr. Celia Chen and Dr. Kathryn Leonard in the Department of Computer Science and by Dr. Jay Daigle in the Department of Mathematics.

 

I'm always happy to chat about anything and everything, feel free to connect with me to grab a cup of coffee!

PDF   Abstract   Bibtex  

Image segmentation is one of the fundamental steps in computer vision. Separating targets from background clutter with high precision is a challenging operation for both humans and computers. Currently, segmenting objects from IR images is done by tedious manual work. The implementation of a Deep Neural Network (DNN) to perform precision segmentation of multi-band IR video images is presented. A customized pix2pix DNN with multiple layers of generative encoder/decoder and discriminator architecture is used in the IR image segmentation process. Real and synthetic images and ground truths are employed to train the DNN. Iterative training is performed to achieve optimum accuracy of segmentation using a minimal number of training data. Special training images are created to enhance the missing features and to increase the segmentation accuracy of the objects. Retraining strategies are developed to minimize the DNN training time. Single pixel accuracy has been achieved in IR target boundary segmentation using DNNs. The segmentation accuracy between the customized pix2pix DNN and simple thresholding, GraphCut, simple neural network and ResNet models are compared.
