The technology of document analysis and recognition (DAR) aims to automatically extract information from document images and handwriting by analyzing the structure and textual contents. It has tremendous applications such as digitization of books and financial notes and information extraction from Web document images. Recognizing text from images, known as Optical Character Recognition (OCR) is the core task of DAR. Recently, OCR has achieved a great success in both scientific research and practical application for different scenes. A traditional OCR system is heavily pipelined, with hand-designed and highly-tuned modules, usually composed of line extraction, word detection, letter segmentation, and then applying different techniques to each piece of a character to figure out what the character is. Nowadays, we have entered a new era of big data, which offers both opportunities and challenges to the field of OCR and DAR. We should seek new OCR and DAR methods to be adaptive to big data, and also push forward new OCR and DAR applications benefited from big data.
Deep learning, which is considered as one of the most significant breakthrough in recent pattern recognition and computer vision fields, has greatly affected these fields and achieved impressive progress in both academy and industry. Currently, deep learning is widely accepted as an effective OCR solution, which first learns to detect text lines or words from images, then recognize the sequence of characters directly from extracted text lines or words. The hand-built and highly tuned modules are avoided in the deep learning-based OCR system. It is expected that the development of deep learning theories and applications would further influence the field of OCR and DAR.
Duguang is an OCR cloud product built by the Vision and Beauty team of Alibaba Group. Over the years, we have been integrating the frontier technology and industry experience, and developing the technological architecture that can be applied to multiple industrial applications, forming a complete technical system of image detection, recognition and understanding. Relying on this, Duguang plays an important role in the field of picture management, search, and intelligent audit within the Alibaba group. Duguang cloud products present high-quality and efficient recognition services, including document images, network pictures, form pictures and card pictures. The professional OCR solutions have been provided for the government, justice, finance and other related industries.
We organize this workshop to provide a forum for highlighting the current research, and discussing some future trends on deep learning for OCR and DAR.
