Edge detection depends on achromatic channel in Drosophila melanogaster.

Edges represent important information in object recognition, and thus edge detection is crucial for animal survival. Various types of edges result from visual contrast, such as luminance contrast and color contrast. So far, the molecular and neural mechanisms underlying edge detection and the relationship between different edge information-processing pathways have been largely undemonstrated. I...

Co-occurrence of color and luminance edges in natural scenes

Spatial resolution for color is poor, and reports that V1 simple cell respond to oriented achromatic stimuli have led to the view of two independent processing streams, a high-resolution achromatic form system and a low-resolution unoriented color surface system. Recent data have challenged this view, showing that V1 simple cells respond also to oriented chromatic stimuli [5, 7] and that color ...

Noisy images edge detection: Ant colony optimization algorithm

The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...

Quantitative properties of achromatic color induction: An edge integration analysis

Edge integration refers to a hypothetical process by which the visual system combines information about the local contrast, or luminance ratios, at luminance borders within an image to compute a scale of relative reflectances for the regions between the borders. The results of three achromatic color matching experiments, in which a test and matching ring were surrounded by one or more rings of ...
