Besides the problems of incorrect perspectives and area outside boundaries, the images captured using mobile devices may have:

  • Shadows
  • Inconsistent lighting

The mobile web capture SDK cleans up the images that are captured using smart phone cameras. Image processing such as noise removal, ink save printing, sharpness, etc. are also available.
