An Ideal Observer Approach to Beamforming
Many signal processing issues in ultrasonic imaging can be viewed as attempts to focus signal energy while preserving the diagnostic information they contain. We have been developing a task-based ideal-observer approach to signal processing with the goal of better understanding the factors that influence the transfer of diagnostic information and improving signal processing algorithms for optim...

متن کاملHow Configural Is the Configural Superiority Effect? A Neuroimaging Investigation of Emergent Features in Visual Cortex
The perception of a visual stimulus is dependent not only upon local features, but also on the arrangement of those features. When stimulus features are perceptually well organized (e.g., symmetric or parallel), a global configuration with a high degree of salience emerges from the interactions between these features, often referred to as emergent features. Emergent features can be demonstrated...
متن کاملFrom Exemplar Theory to Population Coding and Back. An Ideal Observer Approach
Exploiting the analogy between exemplar models and population coding schemes, we characterize, by means of information theoretic tools, the efficiency of a large but finite population of cells coding for a discrete set of categories (e.g. vowels). The optimal code is shown to typically allocate more cells to class boundaries than to regions further apart. We then discuss the predicted perceptua...
متن کاملIdeal observer for heading judgments
Several aspects of the viewing situation affect the ability to determine heading from optical flow. These include the amount of depth variation and number of texture elements in the scene, the location and amount of the visual field stimulated, and the position of the focus of expansion within the stimulus. Without a quantification of the discrimination information provided by the stimuli prese...
