This is quite significant because it proves the existence of (,)-list-decodable codes of good rate with a list-decoding radius much larger than . In other words, the Johnson bound rules out the possibility of having a large number of codewords in a Hamming ball of radius slightly greater than d 2 {\displaystyle {\tfrac {d}{2}}} which means that ...
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
A prefix code is a uniquely decodable code: given a complete and accurate sequence, a receiver can identify each word without requiring a special marker between words. However, there are uniquely decodable codes that are not prefix codes; for instance, the reverse of a prefix code is still uniquely decodable (it is a suffix code), but it is not ...
