商品描述

In real-world applications, new data, patterns, and categories that were not covered by the training data can frequently emerge, necessitating the capability to detect and adapt to novel characters incrementally. Researchers refer to these challenges as the Open-Set Text Recognition (OSTR) task, which has, in recent years, emerged as one of the prominent issues in the field of text recognition. This book begins by providing an introduction to the background of the OSTR task, covering essential aspects such as open-set identification and recognition, conventional OCR methods, and their applications. Subsequently, the concept and definition of the OSTR task are presented encompassing its objectives, use cases, performance metrics, datasets, and protocols. A general framework for OSTR is then detailed, composed of four key components: The Aligned Represented Space, the Label-to-Representation Mapping, the Sample-to-Representation Mapping, and the Open-set Predictor. In addition, possible implementations of each module within the framework are discussed. Following this, two specific open-set text recognition methods, OSOCR and OpenCCD, are introduced. The book concludes by delving into applications and future directions of Open-set text recognition tasks.

This book presents a comprehensive overview of the open-set text recognition task, including concepts, framework, and algorithms. It is suitable for graduated students and young researchers who are majoring in pattern recognition and computer science, especially interdisciplinary research.

商品描述(中文翻譯)

在現實世界的應用中，常常會出現未被訓練數據涵蓋的新數據、模式和類別，這需要能夠增量地檢測和適應新字符的能力。研究人員將這些挑戰稱為開放式文本識別（OSTR）任務，近年來，它已成為文本識別領域中的一個重要問題之一。本書首先介紹了OSTR任務的背景，涵蓋了開放式識別和識別、傳統OCR方法及其應用等重要方面。隨後，介紹了OSTR任務的概念和定義，包括其目標、用例、性能指標、數據集和協議。然後，詳細介紹了OSTR的一般框架，包括四個關鍵組件：對齊表示空間、標籤到表示映射、樣本到表示映射和開放式預測器。此外，還討論了框架中每個模塊的可能實現方式。接下來，介紹了兩種特定的開放式文本識別方法：OSOCR和OpenCCD。本書最後深入探討了開放式文本識別任務的應用和未來發展方向。

本書全面介紹了開放式文本識別任務的概念、框架和算法。適合主修模式識別和計算機科學，尤其是跨學科研究的研究生和年輕研究人員閱讀。
