Elias omega coding is a universal code data compression universal code encoding the positive integers developed by Peter Elias . Like Eliasgammacoding and Elias delta coding , it works by prefixing the integer with a representation of its order of magnitude in a universal code. Unlike those other two codes, however, Elias omega recursively encodes that prefix thus, they are sometimes known as recursive Elias codes . Omega coding is used in applications where the largest encoded value is not known ahead of time, or to Data compression compress data in which small values are much more frequent than large values. To code a number Put a 0 at the end of the representation. If the number to be encoded is 1, stop without recording it if not, add the binary numeral system binary representation of the number as a group to the beginning of the representation. Repeat the previous step, with the number of digits just written, minus 1, as the new number to be encoded. To decode an Elias omega coded integer Start with a variable N , set to a value of 1. Read the first group , which will either be a single 0 , or a 1 followed by N more digits. If it is a 0 , it means the value of the integer is 1 if it starts with a 1 , then N becomes the value of the group interpreted as a binary number. Read each successive group it will either be a single 0 , or a 1 followed by N more digits.

Rate coding is sometimes called frequency coding . This phenomenon was originally shown by Edgar Adrian ED Adrian and Yngve Zotterman Y Zotterman in 1926. ref cite journal title The impulses produced by sensory nerve endings Part II The response of a single end organ. author Adrian ED & Zotterman Y. journal J Physiol Lond. year 1926 volume 61 pages 151 171 http www.ncbi.nlm.nih.gov pmc articles PMC1514782 ref In this simple experiment different weights were hung from a muscle . As the weight of the stimulus increased, the number of spikes recorded from sensory nerves innervating the muscle also increased. From these original experiments Adrian and Zotterman concluded that action potentials were unitary events, and that the frequency of events, and not individual event magnitude, was the basis for most inter neuronal communication.

Merge to Neural coding discuss Talk Neural coding Merger possibilities date July 2010 The correlation coding model of neuron al firing claims that correlations between action potential s, or spikes , within a spike train may carry additional information above and beyond the simple timing of the spikes. It has been theoretically demonstrated that correlation between spike trains can only reduce, and never increase, the total mutual information present in the two spike trains about a stimulus feature. ref KO Johnson, J Neurophysiol. 1980 Jun 43 6 1793 815. ref Any degree of correlation reduces the total entropy thus, by Fisher information Fisher s Information Theorem , correlations can only reduce information. However, this does not prevent correlations from carrying information not present in the average firing rate of two pairs of neurons. A good example of this exists in the pentobarbital anesthetized marmoset auditory cortex, in which a pure tone causes an increase in the number of correlated spikes, but not an increase in the mean firing rate, of pairs of neurons. ref Nature. 1996 Jun 13 381 6583 610 3 ref Contrast this with independent spike coding .

Universal Coding can refer to one of two concepts in data compression Universal code data compression , a fixed prefix code that, for any probability mass function , has a data compression ratio within a constant of the optimal prefix code Universal source coding , a data compression method that limit mathematics asymptotically approaches the data compression ratio of the optimal data compression method, e.g., LZ77 and LZ78 disambig ... more details
Multiple issues orphan February 2009 context April 2008 Motion coding is a technique that can be viewed as extensions of the standard Block matching algorithm block matching techniques in other MPEG standard to image sequences of arbitrary shape. Advanced motion compensation such as overlapped motion compensation and coding of motion vector s for 8x8 blocks, could be used.

Unreferenced auto yes date December 2009 Cover coding is a technique for obscuring the data that is transmitted over an insecure link, to reduce the risks of snooping. An example of cover coding would be for the sender to perform a bitwise Exclusive or XOR exclusive OR of the original data with a password or random number which is known to both sender and receiver. The resulting cover coded data is then transmitted from sender to the receiver, who uncovers the original data by performing a further bitwise Exclusive or XOR exclusive OR operation on the received data using the same password or random number.
