Deep Spectral CNN for Laser Induced Breakdown Spectroscopy

no code implementations3 Dec 2020 Juan Castorena, Diane Oyen, Ann Ollila, Carey Legget, Nina Lanza

This work proposes a spectral convolutional neural network (CNN) operating on laser induced breakdown spectroscopy (LIBS) signals to learn to (1) disentangle spectral signals from the sources of sensor uncertainty (i. e., pre-process) and (2) get qualitative and quantitative measures of chemical content of a sample given a spectral signal (i. e., calibrate).

Diagram Image Retrieval using Sketch-Based Deep Learning and Transfer Learning

no code implementations22 Apr 2020 Manish Bhattarai, Diane Oyen, Juan Castorena, Liping Yang, Brendt Wohlberg

We then use our small set of manually labeled patent diagram images via transfer learning to adapt the image search from sketches of natural images to diagrams.

Motion Guided LIDAR-camera Self-calibration and Accelerated Depth Upsampling for Autonomous Vehicles

no code implementations28 Mar 2018 Juan Castorena, Gint Puskorius, Gaurav Pandey

This work proposes a novel motion guided method for target-less self-calibration of a LiDAR and camera and use the re-projection of LiDAR points onto the image reference frame for real-time depth upsampling.
