Natural images follow statistics inherited by the structure of our physical (visual) environment. In particular, a prominent facet of this structure is that images can be described by a relatively sparse number of features. To investigate the role of this sparseness in the efficiency of the neural code, we designed a new class of random textured stimuli with a controlled sparseness value inspired by measurements of natural images. Then, we tested the impact of this sparseness parameter on the…

Mapping a Complete Neural Population in the Retina
This work shows that the combination of a large, dense multielectrode array and a novel, mostly automated spike-sorting algorithm allowed them to record simultaneously from a highly overlapping population of >200 ganglion cells in the salamander retina, allowing unprecedented access to the complete neural representation of visual information.
Role of Homeostasis in Learning Sparse Representations
By quantitatively assessing the efficiency of the neural representation during learning, a cooperative homeostasis mechanism is derived that optimally tunes the competition between neurons within the sparse coding algorithm.
Sparse models for Computer Vision
It is proposed that bio-inspired approaches may be applied to computer vision using predictive coding schemes, sparse models being one simple and efficient instance of such schemes.
Decorrelation and efficient coding by retinal ganglion cells
It is found that a steep response threshold enhanced efficient coding by noisy spike trains and that the effect of this nonlinearity was near optimal in both salamander and macaque retina.
Coding static natural images using spiking event times: do neurons Cooperate?
Results show that this algorithm provides an efficient spike coding strategy for low-level visual processing which may adapt to the complexity of the visual input.
Adaptation of the simple or complex nature of V1 receptive fields to visual statistics
Normalization of the linear/nonlinear input ratio suggests a previously unknown form of homeostatic control of V1 functional properties, optimizing the network nonlinearities to the statistical structure of the visual input.
Efficient Coding of Spatial Information in the Primate Retina
A novel and unique prediction of efficient coding, the relationships between projection patterns of individual cones to all ganglion cells, was consistent with the observed projection patterns in the retina, indicating a high level of efficiency with near-optimal redundancy in visual signaling by the retina.
Spatial Correlations in Natural Scenes Modulate Response Reliability in Mouse Visual Cortex
This study developed a novel noise-masking method to systematically alter spatial correlations in natural movies, without altering their edge structure, and found that responses in mouse V1 were much less reliable at both the single neuron and population level when spatial correlations were removed from the image.

Sparse Approximation of Images Inspired from the Functional Architecture of the Primary Visual Areas
A sparse approximation scheme inspired from the functional architecture of the primary visual cortex is implemented, which models simple and complex cell receptive fields through log-Gabor wavelets and incorporates inhibition and facilitation interactions between neighboring cells.
