Optimal speed estimation in natural image movies predicts human performance
Accurate perception of motion depends critically on accurate estimation of retinal motion speed. Here, we first analyze natural image movies to determine the optimal space-time receptive fields for encoding local motion speed in a given direction. Next, from the receptive field responses to natural stimuli, we determine the neural computations that are optimal for combining and decoding the res...
متن کاملInternal vs. External Parameters in Fitness Functions
A fitness function is needed for a Genetic Algorithm (GA) to work, and it appears natural that the combination of objectives and constraints into a single scalar function using arithmetic operations is appropriate. One problem with this approach, however, is that accurate scalar information must be provided on the range of objectives and constraints, to avoid one of them from dominating the oth...
متن کاملRunning head: SPEED LIMITS IN NATURAL SCENE DISCRIMINATION Speed Limits: Orientation and Semantic Context Interactions Constrain Natural Scene Discrimination Dynamics
The visual system rapidly extracts information about objects from the cluttered natural environment. In five experiments we quantified the influence of orientation and semantics on the classification speed of objects in natural scenes, particularly with regard to object-context interactions. Natural scene photographs were presented in an object discrimination task, and pattern-masked with vario...

متن کاملInternal vs. external connections for abutments/reconstructions: a systematic review.
OBJECTIVES The objectives of the review were (1) to evaluate the accuracy of implant-level impressions in cases with internal and external connection abutments/reconstructions, and (2) to evaluate the incidence of technical complications of internal and external connection metal- or zirconia-based abutments and single-implant reconstructions. MATERIALS AND METHODS A MEDLINE electronic search ...
