Summary[edit]
| Description |
English: An example of edge detection using an emulation of retinal receptive fields. This is what the output of the optic nerve would look like (as a very rough approximation: the fovea is an almost 1:1 high definition visual area and the receptive fields increase in size from the centre of the retina to the peripheral). This image was processed in Java using a 52-pixel template (contact me for source code). Both types (on centre and off centre) cells are shown in different colours. Here is the original preprocessed image.
Русский: Распознавание границ изображения (краёв, углов) рецептивными полями сетчатки (грубая компьютерная аппроксимация). Размеры рецептивных полей увеличиваются от центра сетчатки к её периферии). Визуальная информация от двух типов клеток (с on- и off-центрами) показана красным и зелёным цветом, соответственно. Автор изображения – User:Simpsons_contributor
