Acceleration of Jaccard's Index Algorithm for Training to Tag Damage on Post-earthquake Images
… Networks (NN) to automatically label damages on images of above ground infrastructure (buildings made of concrete) taken after an earthquake. The goal of the supervised NN is to classify raw input data according to the patterns learned from an input training set. This input training data set is …

Damage Assessment and Strength Predictions in S-Glass/Epoxy Laminates Subjected to Low Energy Impact
… computer program was then used to convert the image files into numeric data, which they were presented to a backpropagation neural network in order to predict the residual compressive strength. Microsoft Excel was used to take the average of the diagonal values of the normalized image data. …

ImagePilot 2.0, A Drawing Interpretation Tool for the Sight-impaired
… to help the sight-impaired interpret electronic images. This new tool, known as ImagePilot 2.0, processes electronic image files that contain line drawings and produces audio feedback to guide the user through the drawing. ImagePilot 2.0 receives input through a pointing device, thereby providing …
