Why Compress Captured Document?
A captured document is a scanned file that can contain images or text as well as audio- visual elements. The file that was a physical document before has been converted into digital format and can be accessed through a computer. These documents are compendious in size and need compressing. Therefore compression software for captured documents is necessary especially in organizations that preserve millions of captured documents on a regular basis; because such a contrivance can compress captured documents to one-hundredth of their actual size, approximately. This enables data transfer at slow internet connectivity and makes archiving and accessing files easy. Compression software for capture document is instrumental in achieving the goal of a paperless office.
How to Compress Captured Documents?
The process of compressing captured documents is very easy. A document, whether text or image, is usually captured through a scanner and is saved in Portable Document Format or PDF file, or other formats. There are downloadable software that can be used for compressing the PDF file. Once the compression software for captured documentis downloaded it can be set up onto the hard disk. The software will ask about particular criteria for compression; once they are specified the compression will happen within seconds.
What are Lossy and Lossless Document Compressions?
Compressing captured documents can be done in two ways - lossy document compression and lossless document compression. Sometimes the compression process needs to be carried out with cent percent optimization to save utmost memory space. In such case a lossy document compression is carried out that leads to a little loss of data that is barely perceptible to human senses. A lossy document compression that is based on transformed coding is used generally for compression of multimedia files. But incase the compressing process should not cause any loss of data no matter how much space the reduced file take, then lossless compression is done. This process of compressing captured document directs the computer to explore the repetitive patterns in the file's code and thereby generate smaller substitutes for the originals. The algorithm methods used here are Huffman coding and arithmetic coding.
