Optical Flow
Computer vision technique that measures the apparent motion of objects between two consecutive images by calculating the displacement vectors of each pixel.
Motion Tracking
Algorithmic process of tracking the position of objects or points of interest throughout a video sequence using detection methods and temporal association.
Action Recognition
Automatic classification of human activities from video sequences by analyzing spatio-temporal motion patterns.
Motion Segmentation
Division of a video into homogeneous regions based on similar motion characteristics, allowing to isolate moving objects.
Temporal Difference
Motion detection method based on calculating pixel-by-pixel differences between successive images to identify areas of change.
Motion Vector
Two-dimensional mathematical representation of the displacement of an image element between two successive frames, composed of magnitude and direction.
Background Subtraction
Segmentation technique that isolates foreground objects by statically modeling the background and subtracting this reference from current images.
Gesture Recognition
Automatic interpretation of significant human movements, typically of hands or body, to control systems or communicate intentions.
Motion Amplification
Video processing technique that subtly accentuates subtle movements to reveal phenomena invisible to the naked eye.
Trajectory Analysis
Quantitative study of paths traveled by objects or entities in video space-time to extract kinematic and behavioral characteristics.
Motion History Image
Static visual representation that encodes temporal motion information in a single image by accumulating time-weighted moving silhouettes.
Dense Optical Flow
Calculation of optical flow for each pixel of the image, providing a complete estimation of the motion field but with high computational complexity.
Sparse Optical Flow
Motion estimation only on selected points of interest (corners, features), reducing computational load while capturing the essence of movement.
Motion Edge Detection
Identification of boundaries between regions of different motion in a video, crucial for segmenting interacting objects.
Human Motion Capture
Precise digital recording of human body movements via markers or computer vision for animation or biomechanical analysis.
Motion Pattern Recognition
Automatic identification of recurring patterns in temporal motion data to classify or predict specific behaviors.
Video Stabilization
Reduction of unwanted shakes in video sequences by estimating and compensating for unintentional camera movements.
Motion Compensation
Video compression technique that predicts future frames by applying motion vectors to reference frames, reducing temporal redundancy.
Motion Interpolation
Generation of intermediate frames by estimating object positions between existing frames, used for slow motion or frame rate enhancement.
