چکیده

This paper presents an integrated approach to parsing textual structure in freeform handwritten notes. Textgraphics classification and text layout analysis are classical problems in printed document analysis, but the irregularity in handwriting and content in freeform notes reveals limitations in existing approaches. We advocate an integrated technique that solves the layout analysis and classification problems simultaneously: the problems are so tightly coupled that it is not possible to solve one without the other for real user notes. We tune and evaluate our approach on a large corpus of unscripted user files and reflect on the difficult recognition scenarios that we have encountered in practice.

Discerning Structure from Freeform Sketches

ion The MultiTree communication protocol abstracts recognizers from one another and from the application. Incrementality Recognition can occur incrementally as new strokes are added to the page with minimal computation, and this is built into the architecture. Efficiency The MultiTree is compact and supports data caching on each of the nodes to allow recognizers to store precomputed values for ...

Structuralizing Freeform Notes by Implicit Sketch Understanding

People are accustomed to capture important events and ideas by sketching notes on papers. Pen and paper offer people great freedom and naturalness to perform these activities. During note sketching, people generally don’t pay much attention to the organization of notes, instead they use implicit spatial relationships and concise informal organizing symbols to structuralize notes. We conducted a...

Finding words in alphabet soup: Inference on freeform character recognition for historical scripts

This paper develops word recognition methods for historical handwritten cursive and printed documents. It employs a powerful segmentation-free letter detection method based upon joint boosting with histogram-of-gradients features. Efficient inference on an ensemble of hidden Markov models can select the most probable sequence of candidate character detections to recognize complete words in ambi...

Context modeling for text/non-text separation in free-form online handwritten documents

Free-form online handwritten documents contain a high diversity of content, organized without constraints imposed to the user. The lack of prior knowledge about content and layout makes the modeling of contextual information of crucial importance for interpretation of such documents. In this work, we present a comprehensive investigation of the sources of contextual information that can benefit...

Estimating Writing Neatness from Online Handwritten Data

Handwriting is the most fundamental expressive activity in learning. In order to utilize the nature, digital pen technology has been emerged to capture notes and transfer them. We have developed AirTransNote, a student note-sharing system that facilitates collaborative and interactive learning in conventional classrooms. With AirTransNote system, a teacher can immediately share student notes to...
