Automatic Document Image Rectification through 3D Boundary Reconstruction
|
Abstract:
When taking bound document with cameras,image distortion occurs because of the warped document surface.An approach was proposed to rectify the bound document image automatically by abstracting document boundaries in the image as the feature information and through parameter controls.Compared with other people's earlier research,the approach is advanced because it does not need manual marking or special equipment.The experiment results can rectify the distorted document image efficiently.
