Sometimes it happens that the acquired images present dirt consists of isolated points blacks, due to dust deposited on the sensors capture or even to electrostatic interference due to overheating of electronic components. The english term used to identify this type of dirt is the word speckle, and the cleaning operation for the identification and removal of these points is defined despeckle. The software tool that perform this type of elaboration do not require a human intervention, are extremely fast and can work on monochrome, gray-scale or color. The most effective can implement advanced algorithms such that the elements while eliminating dirt that prevents very large punctuation marks or dots on the "i" can be removed accidentally.

Not all paper documents are written in "portrait", that is thinking of a sheet of A4 paper, with the natural orientation for reading such that the narrow part is the basis of the paper. Sometimes it happens that graphs, tables, cards and processed similar to be printed in "landscape", thath is always referring to a sheet of A4 paper, with the wide part of the paper as a base. When you scan documents, you always use the same orientation for which we will be left with rotated images correctly for reading, and with no other. To avoid that, during the next consultation document, the operator must repeatedly use rotation functions to be able to correctly read the full document, have been specifically developed functions of auto orientation that allow you to automatically perform this operation in batch, about a group documents, without human intervention. These tools allow then to identify the correct orientation of reading and decide for yourself if the document is straight or whether to automatically rotate images 90, 270 or 180 degrees.
