Abstract
A system that automatically recognizes checkboxes within a document and extracts the contents thereof. A user views a digitized document and annotates the document by identifying checkboxes contained in the document, by way of visually perceptible bounding boxes. The annotated document is processed by a machine learning engine that employs multiple convolutional operations followed by a global average pooling layer, a fully connected layer with 1024 node and ‘ReLU’ activation, a fully connected layer with 2 node and ‘softmax’ activation. The identified checkboxes and their contents are stored as label-value pairs, where the label identifies the checkbox and the value identifies the value of the checkbox, which can be either Yes, No, or No checkbox found.
