Una Red Convolucional Completa (FCN) es una especializada architecture of Redes Neuronales Convolucionales (CNNs) that is particularly effective for segmentación de imágenes tasks. Unlike traditional CNNs, which typically output a single class label for an entire image, FCNs are designed to produce a pixel-wise classification, enabling them to assign a class label to each pixel in the input image.
The main innovation of FCNs is the replacement of fully connected layers with convolutional layers. This allows the network to maintain spatial information throughout the entire processing pipeline. The architecture typically consists of an encoder-decoder structure: the encoder captures the context of the image through downsampling, while the decoder progressively upsamples the feature maps to match the original input size. This configuration allows for precise localization of image features.
FCNs utilize techniques such as skip connections, which concatenate feature maps from the encoder to the decoder at corresponding levels. This helps preserve fine-grained details lost during downsampling, ultimately improving the segmentation quality. FCNs can be applied in various domains, including imagen médica, autonomous driving, and satellite imagery.
En general, las Redes Convolucionales Completas han avanzado significativamente en el campo de visión por computadora by enabling more accurate and detailed image segmentation, making them a vital tool in many AI applications.
