Automatic Recognition of Printed Oriya Script
This paper deals with an Optical Character Recognition (OCR) system for printed Oriya script. The development of OCR for this script is difficult because a large number of character shapes in the script have to be recognized. In the proposed system, the document image is first captured using a flat-bed scanner and then passed through different preprocessing modules like skew correction, line se...
متن کاملKnowledge driven Offline to Online Script Conversion
The problem of offline to online script conversion is a challenging and an ill-posed problem. The interest in offline to online conversion exists because there are a plethora of robust algorithms in online script literature which can not be used on offline scripts. In this paper, we propose a method, based on heuristics, to extract online script information from offline bitmap image. We show th...
متن کاملAutomatic Camera Tracking
Camera tracking for uncalibrated image sequences has now reached a level of maturity where 3D point structure and cameras can be recovered automatically for a significant class of scene types and camera motions. However, problems still occur, and their solution requires a combination of theoretical analysis and good engineering. We describe several such problems including missing data, degenera...
متن کاملAutomatic Camera Exposure Control
It is commonplace to use digital video cameras in robotic applications. These cameras have built-in exposure control but they do not have any knowledge of the environment, the lens being used, the important areas of the image and do not always produce optimal image exposure. Therefore, it is desirable and often necessary to control the exposure off the camera. In this paper we present a scheme ...
متن کاملReliable Automatic Camera-Laser Calibration
Camera-laser calibration is necessary for many robotics and computer vision applications. However, existing calibration toolboxes still require laborious effort from the operator in order to achieve reliable and accurate results. This paper proposes algorithms that augment two existing trustful calibration methods with an automatic extraction of the calibration object from the sensor data. The ...
