We present a statistical approach to skew detection, where the distribution of textual features of document images is modeled as a mixture of straight li...
متن کاملSkew detection and text line position determination in digitized documents
-This paper proposes a computationally efficient procedure for skew detection and text line position determination in digitized documents, which is based on the cross-correlation between the pixels of vertical lines in a document. The determination of the skew angle in documents is essential in optical character recognition systems. Due to the text skew, each horizontal text line intersects a p...
متن کاملHigh-Precision Angle Measuring Technology and High-Precision Angle Sensor
High-resolution and high-precision angle sensors are expected for nanotechnology control system. The technology for manufacturing high-precision disks, and the measurement evaluation technology through the angle calibration system, and the development of a high-resolution optical angle sensor with high-precision and a self-accuracy calibrating function was achieved. This was accomplished using ...
متن کاملSkew angle estimation for printed and handwritten documents using the Wigner-Ville distribution
A skew estimation algorithm for printed and handwritten documents, based on the document’s horizontal projection profile and its Wigner–Ville distribution, is presented. The proposed algorithm is able to correct skew angles that range between 289 and þ898 detecting the right oriented position of the page by the alternations of the horizontal projection profile. It is able of processing successf...
متن کاملA robust and fast skew detection algorithm for generic documents
Abstraet--A robust and fast skew detection algorithm based on hierarchical Hough transform is proposed. It is capable of detecting the skew angle for various document images, including technical articles, postal labels, handwritten text, forms, drawings and bar codes. The algorithm is robust even when black margins introduced by photocopying are present in the image and when the document is sca...
