The visual cortex of mammals use simple cells to detect orientation of edges from information from the eye. These cells can be modelled with a Gabor Filter. This app uses a Gabor Filter to find edges of certain orientations in the similar way to the myriads of simple cells in your brain. The app uses your camera to generate Gabor Filtered images real time. You can modify the Gabor Filters by modifying wavelength, bandwidth, aspect ratio etc of the Gabor function to detect edges in different ways.
