متن کاملSkew Angle Detection and Correction using Radon Transform
In this paper, skew estimation and correction method for document image has been presented. Image of text document can be acquired via camera or other type of machines which cause sometime a skew angle (alignment) on its horizontal direction. To find skew angle of document image, the Radon transform method is used here. The skew angle used in database within the range of ±90o w.r.t x-axis. Kew ...
متن کاملCooperation of multi-layer perceptrons for the estimation of skew angle in text document images
| Estimating the Skew Angle in text document images can be a crucial problem in Optical Character Recognition. Based on a new sensor array processing technique, an original solution to Skew Angle Estimation (SAE) is proposed. Thanks to the reformulation of the SAE problem in the framework of Angle of Arrival theory, a fast and accurate method is presented, that is based on the cooperation of tw...
متن کاملA Family of Skew-Slash Distributions and Estimation of its Parameters via an EM Algorithm
Abstract. In this paper, a family of skew-slash distributions is defined and investigated. We define the new family by the scale mixture of a skew-elliptically distributed random variable with the power of a uniform random variable. This family of distributions contains slash-elliptical and skew-slash distributions. We obtain the moments and some distributional properties of the new family of d...
متن کاملA Flexible Class of Skew Logistic Distribution
‎Here we consider a new class of skew logistic distribution as a generalized mixture of the standard logistic and skew logistic distributions‎, ‎and study some of its important aspects‎. ‎The tail behaviour of the distribution is compared with that of the skew logistic distribution and a location-scale extension of the distribution is proposed‎. ‎Fu...
