Generalizing the Hough transform to detect arbitrary shapes
- D. Ballard
- MathematicsPattern Recognit.
It is demonstrated that color histograms of multicolored objects provide a robust, efficient cue for indexing into a large database of models and that they can differentiate among a large number of objects.
Predictive coding in the visual cortex: a functional interpretation of some extra-classical receptive-field effects.
Results suggest that rather than being exclusively feedforward phenomena, nonclassical surround effects in the visual cortex may also result from cortico-cortical feedback as a consequence of the visual system using an efficient hierarchical strategy for encoding natural images.

Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions and this target article focuses on how deictic bindings make it possible to perform natural tasks.
Eye movements in natural behavior
Memory Representations in Natural Tasks
A series of experiments are designed to test the use of short-term memory in the course of a natural hand-eye task where subjects have the freedom to choose their own task parameters and reduce the instantaneous memory required to perform the task by serializing the task with eye movements.
Eye guidance in natural vision: reinterpreting salience.
It is argued that there is a need to move away from this class of model and find the principles that govern gaze allocation in a broader range of settings, because the stimulus context is limited, and the dynamic, task-driven nature of vision is not represented.
