Deep Learning and Convolutional Neural Networks

Convolutional Neural Networks (CNN)

Convolutional Neural Networks (CNN) are a type of deep learning algorithm specifically designed for image processing tasks. CNNs are inspired by the visual cortex structure in the human brain, as they contain layers that mimic the neurons’ ability to detect and understand visual patterns. By leveraging convolutional layers, pooling, and fully connected layers, CNNs can extract hierarchical features from images, enabling accurate classification, segmentation, and object recognition tasks.

CNN Architecture for Image Processing

The architecture of CNNs for image processing typically consists of multiple layers, including convolutional layers, pooling layers, and fully connected layers. Convolutional layers apply filters to an input image, enabling the network to capture local patterns and features. Pooling layers downsample the convolved features, reducing the computational complexity and enhancing the network’s translation invariance. Finally, fully connected layers aggregate the extracted features and make a prediction or classification based on the learned representations. CNN architectures can vary in depth, width, and connectivity, depending on the complexity of image processing tasks and the available computational resources.
