Remarks
This processing command is designed to determine orientation of images containing mostly text in Roman alphabet which is rotated by multiple of 90 degrees (e.g., scanned documents with unknown orientation).
The command is not designed for:
Use Vintasoft.Imaging.ImageProcessing.Document.DeskewCommand prior to this command to align the rotated image. Use other processing commands prior to this command to improve the detection quality of image with noise.
The command is not designed for:
- non-textual images
- non-Roman text
- Roman text with only capital letters
- rotated text with rotation angle other than multiple of 90 degrees (use Vintasoft.Imaging.ImageProcessing.Document.DeskewCommand)
- images with only few words, insufficient for making a conclusion
Use Vintasoft.Imaging.ImageProcessing.Document.DeskewCommand prior to this command to align the rotated image. Use other processing commands prior to this command to improve the detection quality of image with noise.
