Image Segmentation
Image segmentation is the process of partitioning an image into meaningful regions or classifying each pixel into a category. It is used in medical imaging, autonomous driving, and satellite analysis.
Understanding Image Segmentation
Image segmentation is a computer vision task that partitions an image into distinct regions or assigns a class label to every individual pixel. Unlike image classification, which labels the entire image, segmentation provides precise spatial understanding of where objects and boundaries exist. Semantic segmentation labels every pixel with a category, instance segmentation distinguishes individual objects of the same class, and panoptic segmentation combines both approaches. Architectures like U-Net, Mask R-CNN, and the Segment Anything Model (SAM) have driven major advances. Image segmentation is essential in medical imaging for delineating tumors and organs, in autonomous driving for understanding road scenes, and in satellite imagery for land-use mapping. The task requires models to capture both local details and global context across the image.

Bounding Box
A bounding box is a rectangular border drawn around an object in an image to indicate its location and extent. Bounding boxes are the primary output format for object detection models.
Computer Vision
Computer vision is a field of AI that enables machines to interpret and understand visual information from images and videos. Applications include facial recognition, autonomous driving, medical imaging, and augmented reality.
Face Recognition
Face recognition is a computer vision technology that identifies or verifies individuals by analyzing facial features in images or video. It is used in security systems, phone unlocking, and photo organization.
Image Captioning
Image captioning is the AI task of generating natural language descriptions of images. It requires both visual understanding (computer vision) and text generation (NLP) capabilities.
Image Classification
Image classification is the computer vision task of assigning a label to an entire image based on its visual content. Deep learning models like ResNet and Vision Transformers achieve near-human accuracy on this task.
Instance Segmentation
Instance segmentation is a computer vision task that identifies each object in an image and delineates its exact pixel boundary. Unlike semantic segmentation, it distinguishes between individual instances of the same class.
Masked Autoencoder
A masked autoencoder is a self-supervised learning method that masks random patches of an image and trains the model to reconstruct them. It has proven highly effective for pre-training vision models.
Neural Radiance Field
A Neural Radiance Field (NeRF) is a deep learning method that represents 3D scenes as continuous functions, enabling photorealistic novel view synthesis from 2D images. NeRFs have transformed 3D reconstruction and rendering.
