Second-order statistics of natural images
Assuming adaptation of the visual cortex to its environment, we analyse the invariance found in natural images to explain the selective response of visual cortical neurons. We argue that the invariant structure of images can be formally expressed by dot-products. Utilizing the specific structure of the proposed model we show how non-linear functions can be learned efficiently from natural image...
متن کاملStatistics of Natural Time-Varying Images
Natural time-varying images possess substantial spatiotemporal correlations. We measure these correlations | or equivalently the power spectrum | for an ensemble of more than a thousand segments of motion pictures, and we nd signi cant regularities. More precisely, our measurements show that the dependence of the power spectrum on the spatial frequency, f , and temporal frequency, w, is in gene...
متن کاملStatistics of Natural Images and Models
Large calibrated datasets of 'random ' natural images have recently become available. These make possible precise and intensive statistical studies of the local nature of images. We report results ranging from the simplest single pixel intensity to joint distribution of 3 Haar wavelet responses. Some of these statistics shed light on old issues such as the near scale-invariance of image statist...
متن کاملStatistics of gradient directions in natural images
Interest in finding statistical regularities in natural images has been growing since the advent of information theory and the advancem ent o f the efficient coding hypothesis that the human visual system is optimised to encode natural visual stimuli. In this thesis, a statistical analy sis o f gradient directions in an ensem ble o f natural images is reported. Inform ation-theoretic measures ...
متن کاملNatural Tasking of Robots Based on Human Interaction Cues
When a person gives a task to another person there are at least two sorts of very human processes at work. At the surface level, each person both displays and perceives cross-cultural cues which regulate the interaction. Through facial expressions, body posture, and utterances, the student unconsciously speeds or slows the rate at which the instructor is teaching and directs the instructor to p...
