Toolkit for document image processing
Project description
Contextualization
In progress toolkit for document image pre processing.
Aimed for images to be OCRed.
Available methods
-
Auto rotate image
Uses left margin of a document to calculate the angle of rotation present, and correct it accordingly.
Can be given the rotation direction (clocwise or counter_clockwise), or in auto mode tries to determine the side to which the document is tilted (can be none, in which case image won't be rotated).
-
Calculate rotation direction
Calculates rotation direction of an image by finding the biggest sets of the first black pixels appearances (with outliers removed) in the image for each direction: clockwise, counter_clockwise and none.
For none direction, the set is created based on pixels with same 'x' coordinate that with less than a 5% height difference, relative to the image's height.
