3D Convolutional Neural Networks (3D-CNNs) are a class of deep learning architectures designed to process volumetric data, sequences of images, or spatial-temporal datasets. Unlike traditional 2D CNNs that operate on two-dimensional image slices, 3D-CNNs extend convolution operations into three dimensions, enabling the model to capture complex spatial and temporal features. They are widely used in medical imaging (e.g., MRI, CT scans), video analysis, and other applications requiring the understanding of three-dimensional structures or sequences.
