RT Conference Proceedings T1 The effect of image enhancement algorithms on convolutional neural networks A1 Rodríguez Rodríguez, José Antonio A1 Molina-Cabello, Miguel Ángel A1 Benítez-Rochel, Rafaela A1 López-Rubio, Ezequiel K1 Redes neuronales artificiales K1 Visión por ordenador AB Convolutional Neural Networks (CNNs) are widely used due to their high performance in many tasks related to computer vision. In particular, image classification is one of the fields where CNNs are employed with success. However, images can be heavily affected by several inconveniences such as noise or illumination. Therefore, image enhancement algorithms have been developed to improve the quality of the images. In this work, the impact that brightness and image contrast enhancement techniques have on the performance achieved by CNNs in classification tasks is analyzed. More specifically, several well known CNNs architectures such as Alexnet or Googlenet, and image contrast enhancement techniques such as Gamma Correction or Logarithm Transformation are studied. Different experiments have been carried out, and the obtained qualitative and quantitative results are reported PB IEEE SN 9781728188089 SN 1051-4651 YR 2021 FD 2021 LK https://hdl.handle.net/10630/44902 UL https://hdl.handle.net/10630/44902 LA eng DS RIUMA.
