چکیده

Skew detection is an important stage of document image processing. It is desirable t o have a fast, all-purpose skew detector. This paper describes a fast skew detector using directional profile analysis. It can quickly and accurately detect skew on a wide variety of document images, including images with multiple text alignments and nontext regions. The complexity of the skew detection process directly depends on the document layout complexity.

Skew Detection for Complex Document Images Using Fuzzy Runlength

A skew angle estimation approach based on the application of a fuzzy directional runlength is proposed for complex address images. The proposed technique was tested on a variety of USPS parcel images including both machine print and handwritten addresses. The testing results showed a successful rate more than 90% of the test set.

Two Phase Data Reduction for Hough Transformation to Detect Skew

An important pre-processing task in an automated document image processing system is detection of skew in the image. Skew detection and correction is the first step in the document analysis and understanding processing steps. Correction the skewed scanned document image is very important, because it has a direct effect on the reliability and efficiency of the segmentation and feature extraction...

Skewscope: The Textual Document Skew Detector

Skewscope is a software module designed to detect and analyze skew information of textual document images. Its skew detection algorithm, which is the major topic of this paper, directly computes the slopes of all unique pairs of components and draws skew information from their distribution profile. Its validity is examined by using the complete set of University of Washington English Document I...
