This paper describes how opt imal video preprocessor performance can be achieved using a software recogni t ion system and a set of control led exper iments. It basical ly involves opt imizing on a constant threshold and then using recognit ion logic designed f r om that threshold to optimize an adaptive threshold function or threshold operator. By using this technique, the video preprocessor c...

The importance of effectively retrieving OCR text has grown significantly in recent years. We provide a brief overview of work done to improve the effectiveness of retrieval of OCR text.

IMPROVING TEXT RECOGNITION IN IMAGES OF NATURAL SCENES

The problem of recognizing mathematical expressions differs significantly from the recognition of standard prose. While in prose significant constraints can be put on the interpretation of a character by the characters immediately preceding and following it, few such simple constraints are present in a mathematical expression. In order to make the problem tractable, effective methods of recogni...

Existing literature reveals that during reading, gaze fixations within a word are not necessarily close to the optimal reading position. The optimal position for reading represents the gaze fixation near the center of each word for which recognition time is minimal. In our study, we examined the match between optimal position and initial fixation position, which has not been studied before. We ...

In this paper we prove that, if V is a κ-tame pseudovariety which satisfies the pseudoidentity xyz = xyz, then the pseudovariety join LSl∨V is also κ-tame. Here, LSl denotes the pseudovariety of local semilattices and κ denotes the implicit signature consisting of the multiplication and the (ω − 1)-power. As a consequence, we deduce that LSl ∨V is decidable. In particular the joins LSl ∨ Ab, LS...

Stroke extraction is of great significance for an offline character recognition system. In this paper, we present an efficient stroke extraction method based on a combination of a simple feature point detection scheme and a novel stroke segment connecting method. The algorithm can fast and accurately extract the strokes from the thinned Chinese character images. Experimental results on a large ...
