Balanced codes have the property that no codeword is “contained” in another. This property makes balanced codes attractive for certain applications, such as the encoding of unchangeable data on a laser disk. Donald E. Knuth [1] described a balanced code with 2p information bits and p parity bits, for which serial encoding and decoding is especially ...

Vectograph coding; Efficient coding of line drawing
Computer Vision, Graphics, and Image Processing, 1985Abstract A method for the efficient coding of line drawings is discussed. The intent is to provide an extremely low bandwidth representation for images, preserving “intelligible” image content but not necessarily image quality. This has led to an image transformation involving edge enhancement, detection, line thinning, and polygonal splining which ...

Binocular summation and efficient coding
Vision Research, 2021Two eyes are better than one at detecting a pattern, an advantage termed binocular summation. It is widely believed that binocular summation is mediated by neurons that sum the two eyes' inputs. Here we suggest an alternative model based on a model of binocular interactions proposed by Cohn, Leong & Lasley (Vision Research, 1981, 21, 1017-1023) and ...

Design of efficient balanced codes
IEEE Transactions on Computers, 1994A class of balanced (or DC-free) codes that are useful for unidirectional and asymmetric error detection is defined. Optimal (serial and parallel) balanced codes are constructed. >

Simple codes versus efficient codes
Current Opinion in Neurobiology, 1995Transmission of information is an important function of cortical neurons, so it is conceivable that they have evolved to transmit information efficiently, with low noise and high temporal precision. Such precision is consistent with the output generated by various working models that mimick neuronal activity, from simple integrate-and-fire models to ...

Speech coding using efficient block codes
ICASSP '82. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Digital coders invariably introduce errors into analog signals such as speech. The importance of adjusting the spectrum of the error so as to minimize the subjective distortion is now well recognized. The optimum noise spectrum for minimum subjective distortion is in general non-flat.

IEEE Transactions on Circuits and Systems for Video Technology, 2012
The compression capability of several generations of video coding standards is compared by means of peak signal-to-noise ratio (PSNR) and subjective testing results. A unified approach is applied to the analysis of designs, including H.262/MPEG-2 Video, H.263, MPEG-4 Visual, H.264/MPEG-4 Advanced Video Coding (AVC), and High Efficiency Video Coding ...

On video formats and coding efficiency
1999 Digest of Technical Papers. International Conference on Consumer Electronics (Cat. No.99CH36277), 2001This paper examines the efficiency of MPEG-2 coding for interlaced and progressive video, and compares de-interlacing and picture rate up-conversion before and after coding. We found receiver side de-interlacing and picture rate up-conversion (i.e. after coding) to give better image quality at a given data rate. In contrast with some other publications,
