Figure-Ground Discrimination in the Visual System of Drosophila melanogaster
Drosophila inelanog~lster is able to detect a small visual object hidden in a background of identical texture, as long as there is relative motion between their retinal images. The properties of figurc-ground discrimination in the walking fly are studied under experimental conditions where the positions of figure and ground oscillate sinusoidally with similar frequency and similar amplitude but...

Visual processes deal with analyzing images and extracting information from them. They play an important role in many of todays industries, e.g., in the medical instrument industry, the electronic and micro-electronic industry, the movie industry, the robotics industry, and in many other elds which require automatic extraction of visual information from images. One of the major di culties in im...
متن کاملGround from Figure Discrimination
This paper proposes a new, e cient, gure from ground discrimination method. This algorithm is based on the assumption that background data features can be more easily detected than gure data features, thus emphasizing the background detection task (and implying the name of the method). Along the iterative labeling process, data features are sequentially and permanently labelled as "background",...

متن کاملFigure–ground discrimination behavior in Drosophila. I. Spatial organization of wing-steering responses
The behavioral algorithms and neural subsystems for visual figure-ground discrimination are not sufficiently described in any model system. The fly visual system shares structural and functional similarity with that of vertebrates and, like vertebrates, flies robustly track visual figures in the face of ground motion. This computation is crucial for animals that pursue salient objects under the...
