Abstract: Technologies for document evaluation and identification of shared textual substrings between documents are described herein. Documents are evaluated and organized according to textual elements within the documents. A suffix index is generated from a reference document. The suffix index is used to identify common substrings of text within query documents using variable evaluation windows within the query documents. Indications of overlapping textual information between the reference document and query documents is generated as an output.

Abstract: First image data including a plurality of values representing the image in one or more first spectral bands of an electromagnetic spectrum is received. Second image data including a plurality of values representing the image in one or more second spectral bands of the electromagnetic spectrum is determined based on the first image data. The one or more second spectral bands of the electromagnetic spectrum include at least one spectral band not included in the one or more first spectral bands of the electromagnetic spectrum. The second image data is stored in a memory and/or provided to a user device for displaying the image in one or more second bands of the electromagnetic spectrum to a user of the user device.
