For typical images, the values of adjacent pixels are highly correlated; that is, a great deal of information about a pixel value can be obtained by inspecting its neighboring pixel values. This property is exploited in predictive coding techniques where an attempt is made to predict the value of a given pixel based on the values of the surrounding ...

Predictive coding: Neuroscience and art
2020This paper examines the applicability of predictive coding as an explanatory model for perception. This is carried out from two perspectives. First, the central assumptions of the model are re-examined in light of the neuroscientific evidence for the structure and functioning of key brain areas involved in perception. The inferential processes involved

Neuronal Dynamics of Predictive Coding
The Neuroscientist, 2001A critical task of the central nervous system is to learn causal relationships between stimuli to anticipate events in the future, such as the position of a moving prey or predator. What are the neuronal phenomena underlying anticipation? In this article, I review recent results in hippocampal electrophysiology that shed light on this issue.

In a general predictive coding scheme, the correlation between the neighboring pixel values is used to form a prediction for each pixel. By far, the most common approach to predictive coding is differential pulse code modulation (DPCM). In DPCM, the prediction is subtracted from the actual pixel value to form a differential image that is much less ...
