Analysis and Categorization of 2D Multi-touch Gesture Recognition Techniques
Abstract: Various techniques have been implemented for wide variety of gesture recognition applications. However, discerning the best technique to adopt for a specific gesture application is still a challenge. Wide variety, complexity in the gesture and the need for complex algorithms make implementation of recognition difficult even for basic gesture applications. In this thesis, different techniques for two dimensional (2D) touch gestures are reviewed, compared and categorized based on user requirements of the gesture applications. This work introduces two main paradigms for gesture applications: a) gestures for direct manipulation and navigation, b) gesture-based languages. These two paradigms have specific and separate roles in 2D touch gesture systems. To provide the clear distinction between two paradigms, three different algorithms are implemented for basic to complex 2D gestures using simple sometimes, as well as complex techniques such as linear regression and Hidden Markov Models. Thereafter, these algorithms are analyzed based on their performance and their fit with application requirements.
Document Analysis and Recognition – ICDAR 2021
This four-volume set of LNCS 12821, LNCS 12822, LNCS 12823 and LNCS 12824, constitutes the refereed proceedings of the 16th International Conference on Document Analysis and Recognition, ICDAR 2021, held in Lausanne, Switzerland in September 2021. The 182 full papers were carefully reviewed and selected from 340 submissions, and are presented with 13 competition reports. The papers are organized into the following topical sections: historical document analysis, document analysis systems, handwriting recognition, scene text detection and recognition, document image processing, natural language processing (NLP) for document understanding, and graphics, diagram and math recognition.
