Image Upload Quality Requirements
Below are the requirements for size and quality for document images uploaded to AIO.
Meeting these requirements will result in successful image processing by AIO which will ease and speed the process.
Good lighting
Make sure that the image is not too dark or too bright.
Avoid reflections
Avoid glares and reflections. We recommend not to use flash when capturing document images.
Focus and sharpness
Make sure the image is clear and there are no blurred areas.
Angle
The image angle should align with the document. Horizontal or vertical tilt angle shouldn’t exceed 10 degrees.
Margins (too small)
Make sure there is minimal space around the document. It is recommended that the document takes up 70-80% of the image.
Margins (too big)
Make sure the space around the document does not take up more than 20-30% of the image. It is recommended that the document takes up 70-80% of the image.
Contrast
Ensure that the document is in clear contrast to the background. Avoid light-colored document on a light background, as well as a dark-colored document on a dark background.
Image Resolution
High resolution images improve the document recognition and analyzing results. We recommend using resolution of at least Full HD (1920×1080) and autofocus.
Extraneous objects
Make sure that body parts or other objects do not cover the document data.
Orientation
Make sure that the orientation (portrait or landscape) of the image and the document are the same.
Single document
Include a single document in an image and avoid multiple documents inside the same image.
