With a total of 4 patents, Agarwal's work focuses on enhancing the accuracy and efficiency of text recognition technologies.

Latest Patents

One of Agarwal's latest patents is titled "Local connectivity feature transform of binary images containing text characters for optical character/word recognition." This invention applies a local connectivity feature transform (LCFT) to binary document images containing text characters. The transformed images are then input into a bi-directional Long Short Term Memory (LSTM) neural network for character and word recognition. The LCFT transformed image is a grayscale image where pixel values encode local pixel connectivity information from the original binary image. The transform provides a unique score for every possible shape represented as a 3×3 block.

Another significant patent is "Text image processing using stroke-aware max-min pooling for OCR system employing artificial neural network." This method digitizes printed text images using an LSTM network. Text images are pre-processed with a stroke-aware max-min pooling method before being fed into the network for both training and prediction. During training, an average stroke thickness is computed, and pooling is applied based on the stroke thickness of the text line images.
