Convolutional Neural Networks (CNNs) have revolutionized the field of computer vision. They are designed to process data with a grid-like topology, making them particularly effective for image recognition and classification tasks. CNNs automatically and adaptively learn spatial hierarchies of features through backpropagation by using multiple building blocks, such as convolution layers, pooling layers and fully connected layers. This architecture allows CNNs to capture local patterns and assemble them into complex, abstract representations.
However, a new player has entered the arena: Vision Transformers (ViTs). Inspired by the success of transformers in natural language processing, ViTs apply self-attention mechanisms to image recognition tasks. Unlike CNNs, which focus on local connectivity, ViTs can capture global relationships within the data, leading to improved performance on large-scale image recognition challenges. Research has shown that ViTs can outperform state-of-the-art CNNs when trained on sufficiently large datasets, indicating a potential shift in the foundational architectures used in computer vision.
Enhanced Image Processing and Analysis
The advancements in neural networks have significantly enhanced image processing and analysis capabilities. Techniques like semantic segmentation, where each pixel of an image is classified into a category, enable detailed understanding of the scene. Instance segmentation takes this further by identifying individual instances of objects within the same category.
Real-world Applications:
Medical Imaging: In healthcare, these techniques assist in early diagnosis by accurately identifying and segmenting anomalies in medical scans, such as tumors or lesions, enabling prompt and targeted treatment.

Unsupervised learning methods enable models to learn from unlabeled data by discovering hidden patterns and structures.
Generative Models:
Generative Adversarial Networks (GANs): GANs consist of two networks—the generator and the discriminator—that compete against each other. The generator creates synthetic data, while the discriminator evaluates its authenticity. This competition results in the generation of highly realistic synthetic images, which can be used to augment training datasets.
Variational Autoencoders (VAEs): VAEs learn to encode input data into a latent space and then decode it back to reconstruct the input. They are useful for tasks like image reconstruction and generating new images with similar characteristics.
These generative models help overcome the limitations of labeled data scarcity and improve the robustness and generalization of computer vision models.
