Computer vision aims to provide computers with the ability to perceive and comprehend visual data, similar to how humans do.

Image segmentation involves dividing an image into distinct regions or segments. Edge detection, region growing, and clustering are commonly used techniques for this purpose.

Feature extraction aims to extract meaningful and distinctive characteristics from an image that can be used for various tasks such as object recognition, classification, and tracking.

Convolutional Neural Networks (CNNs) are widely used for image classification tasks due to their ability to learn hierarchical features and their effectiveness in capturing spatial relationships within an image.

Depth estimation refers to the process of determining the distance between the camera and various points in a scene based on information extracted from a single image.

Image filtering involves applying mathematical operations to modify the pixel values of an image to achieve various effects such as noise reduction, edge detection, and sharpening.

Object detection, recognition, and classification are closely related tasks in computer vision. Object detection involves identifying the presence of objects in an image, object recognition involves identifying the specific type of object, and object classification involves assigning a category label to the object.

Image mosaicking is the process of combining multiple images with overlapping regions to create a single, seamless panoramic image.

3D reconstruction involves estimating the 3D structure of an object from multiple 2D images taken from different viewpoints.

The Kalman filter is a widely used technique for object tracking in videos. It is a recursive filter that estimates the state of an object (e.g., position and velocity) over time based on noisy measurements.

Image captioning involves generating natural language descriptions or captions for images, enabling computers to understand and describe visual content.

The Viola-Jones algorithm is a widely used approach for face detection. It utilizes Haar-like features and a cascade of classifiers to efficiently detect faces in images.

Camera pose estimation involves determining the position and orientation of a camera in 3D space based on information extracted from a single image.

The median filter is a widely used technique for image denoising. It replaces each pixel with the median value of its neighboring pixels, effectively removing noise while preserving edges.

Text-to-image synthesis involves generating realistic images from a natural language description. This task requires the model to understand the semantics of the text and generate visually plausible images.
