FCN — Fully Convolutional Network

Fact

A neural network that uses only convolution layers to predict every pixel.

In Plain Words

FCN treats a photo like a coloring book page. It colors every tiny square: cat here, couch there.

You meet it in medical scans and self-driving car vision. It gives pixel positions, not one big label.

CNN
FCN is a dense prediction version of CNN. It outputs a pixel map.

Image Segmentation
FCN helped image segmentation move from whole-image labels to pixel labels.

U-Net
U-Net follows the fully convolutional idea and improves detail blending.
