  PyTorch CRNN: Seq2Seq Digits Recognition w/ CTC

  This article discusses handwritten character recognition (OCR) in images using sequence-to-sequence (seq2seq) mapping performed by a Convolutional Recurrent Neural Network (CRNN) trained with Connectionist Temporal Classification (CTC) loss. The aforementioned approach is employed in multiple modern OCR engines for handwritten...

  Improving Tesseract 4's OCR Accuracy through Image Preprocessing

  In this work I took a look at Tesseract 4’s performance at recognizing characters from a challenging dataset and proposed a minimalistic convolution-based approach for input image preprocessing that can boost the character-level accuracy from 13.4% to 61.6% (+359% relative...

  PyTorch Iterative FGVM: Targeted Adversarial Samples for Traffic-Sign Recognition

  Inspired by the progress of driverless cars and by the fact that this subject is not thoroughly discussed I decided to give it a shot at creating smooth targeted adversarial samples that are interpreted as legit traffic signs with a...
