چکیده

Text/graphics separation aims at segmenting the document into two layers: a layer assumed to contain text and a layer containing graphical objects. In this paper, we present a consolidation of a method proposed by Fletcher and Kasturi, with a number of improvements to make it more suitable for graphics-rich documents. We discuss the right choice of thresholds for this method, and their stability. We also propose a post-processing step for retrieving text components touching the graphics, through local segmentation of the distance skeleton.

Directional Stroke Width Transform to Separate Text and Graphics in City Maps

One of the complex documents in the real world is city maps. In these kinds of maps, text labels overlap by graphics with having a variety of fonts and styles in different orientations. Usually, text and graphic colour is not predefined due to various map publishers. In most city maps, text and graphic lines form a single connected component. Moreover, the common regions of text and graphic lin...

Text/Graphics Separation and Skew Correction of Text Regions of Business Card Images for Mobile Devices

Separation of the text regions from background texture and graphics is an important step of any optical character recognition system for the images containing both texts and graphics. In this paper, we have presented a novel text/graphics separation technique and a method for skew correction of text regions extracted from business card images captured with a cell-phone camera. At first, the bac...

A Proposed Scheme for Performance Evaluation of Graphics/Text Separation Algorithms

We propose an objective, comprehensive, and complexity independent metric for performance evaluation of graphics/text separation (text segmentation) algorithms. The metric includes a positive set and a negative set of indices, at both the character and the character string (text) levels, and it evaluates the detection accuracy of the location, width, height, orientation, skew, string length, an...

Text/Graphics Separation in Maps

The separation of overlapping text and graphics is a challenging problem in document image analysis. This paper proposes a specific method of detecting and extracting characters that are touching graphics. It is based on the observation that the constituent strokes of characters are usually short segments in comparison with those of graphics. It combines line continuation with the feature line ...
