Another look at retina as an image scalar quantizer
We present a novel quantization algorithm based on a biologically realistic vertebrate retina model. Our aim is to investigate the retina transfer function that maps a continuous input signal into a binary-like neural code. We, furthermore, describe a possible decoding procedure. The coder/decoder, we describe here, focuses on the temporal behavior of the three last retina layers. The neural co...
متن کاملStreaming an image through the eye: The retina seen as a dithered scalable image coder
We propose the design of an original scalable image coder/decoder that is inspired from the mammalians retina. Our coder accounts for the time-dependent and also nondeterministic behavior of the actual retina. The present work brings two main contributions: As a first step, (i) we design a deterministic image coder mimicking most of the retinal processing stages and then (ii) we introduce a ret...
متن کاملContrast sensitivity as a function of position on the retina.
Contrast sensitivity has been measured as a function of the eccentricity along several meridians. The measurements were carried out with a two-dimensional sinusoidal grating (cross grating) presented in a surround with a luminance equal to the average stimulus luminance. The advantage of this stimulus over a one-dimensional grating is that it permits presentation of small-sized stimuli. in a su...
متن کاملCompressed-Sampling-Based Image Saliency Detection in the Wavelet Domain
When watching natural scenes, an overwhelming amount of information is delivered to the Human Visual System (HVS). The optic nerve is estimated to receive around 108 bits of information a second. This large amount of information can’t be processed right away through our neural system. Visual attention mechanism enables HVS to spend neural resources efficiently, only on the selected parts of the...
متن کاملAdjoining to Wythoff's Game its P-Positions as Moves
A rewarding method for generating a new game ? i+1 from a known game ? i is to adjoin an appropriate subset of the P-positions (2nd player winning positions) of ? i to ? i+1 as moves. We illustrate this statement by adjoining to the generalized Wythoo Game three subsets of its P-positions as moves, resulting in three diierent classes of games. We analyze these classes, characterizing the P-posi...
