CNNs leverage convolutional layers to automatically learn spatial hierarchies of features from image data. Convolutional layers consist of a set of learnable filters that convolve across the input image, extracting local patterns. Pooling layers are then used to reduce the spatial resolution of the feature maps, making the model more invariant to translations and distortions. CNNs have achieved remarkable success in a wide range of computer vision tasks, owing to their ability to automatically learn relevant features from image data. However, CNNs can have difficulty capturing long-range dependencies in images, and they can be computationally expensive to train, particularly for high-resolution images.
Transformers
Originally developed for natural language processing, Transformers have become increasingly popular in computer vision, particularly for tasks that require capturing long-range dependencies. Transformers employ an attention mechanism to focus on the most relevant parts of an image. The attention mechanism allows the model to weigh the importance of different parts of the image when making predictions. This is particularly useful for tasks such as image captioning and visual question answering, where the model needs to understand the relationships between different objects in the image. Transformers have demonstrated state-of-the-art performance on a variety of computer vision benchmarks. However, Transformers are computationally demanding and require large amounts of training data.
