An Investigation of Feature Selection and Transfer Learning for Writer-Independent Offline Handwritten Signature Verification

Victor L. F. Souza, Adriano L. I. Oliveira, Rafael M. O. Cruz +1

SigNet is a state of the art model for feature representation used for handwritten signature verification (HSV). This representation is based on a Deep Convolutional Neural Network…

KutralNet: A Portable Deep Learning Model for Fire Recognition

Angel Ayala, Bruno Fernandes, Francisco Cruz +3

Most of the automatic fire alarm systems detect the fire presence through sensors like thermal, smoke, or flame. One of the new approaches to the problem is the use of images to pe…
