we saw the various formats in which enterprises receive documents for information extraction and the role of foundational technology in enabling it. We also observed the challenges faced, such as noise, quality, ROI detection, document classification and many more. Now, I will explain how an extraction solution built on top of the foundational technologies can address these challenges. Below are some of the solution elements that solve specific extraction problems:
Noise elements and quality issues: Image correction techniques are applied to reduce and correct the noise present in the document. Geometrical affine transformations can help correct tilt and orientation issues. Gaussian and Laplacian filters can be applied to remove noise from the document image. Background logos, textures and patterns can also be removed using thresholding techniques.
