Clustering

StarStarStarStar

Groups data into clusters based on similarity without pre-labeled categories. Applied in image segmentation and object categorization.

StarStarStarStar

Random Forests

StarStarStarStar

An ensemble learning method constructing multiple decision trees during training and outputting the class that is the mode of the classes of the individual trees. Employed in scene labeling and detection tasks.

StarStarStarStar

Hidden Markov Model (HMM)

StarStarStarStar

Statistical model where the system being modeled is assumed to be a Markov process with hidden states. Used in speech and handwriting recognition.

StarStarStarStar

Support Vector Machines (SVM)

StarStarStarStar

Supervised learning model that finds the hyperplane maximizing the margin between classes. Used for classification and regression tasks.

StarStarStarStar

Feature-Based Method

StarStarStarStar

Identifies unique features within an image and uses them to compare different images. Common in image stitching and 3D reconstruction.

StarStarStarStar

Bayesian Classification

StarStarStarStar

Applies Bayes' theorem with strong independence assumptions between the features. It's applied in spam detection and medical diagnosis.

StarStarStarStar

Template Matching

StarStarStarStar

Compares a template image to an input image, aiming to detect instances of the template. Used in object detection and quality control.

StarStarStarStar

Bag of Visual Words (BoVW)

StarStarStarStar

A model used for image classification, based on the idea of representing images through the histogram of visual words. Effective in texture and object recognition.

StarStarStarStar

Neural Networks

StarStarStarStar

Computational models inspired by the human brain, capable of learning patterns from data. Essential in facial recognition and autonomous vehicles.

StarStarStarStar

Decision Trees

StarStarStarStar

Tree-like model used for decision making by creating a flowchart-like structure. Utilized in object classification and image categorization.

StarStarStarStar

Principal Component Analysis (PCA)

StarStarStarStar

A statistical process that uses orthogonal transformation to convert a set of observations into a set of linearly uncorrelated variables. Applied in face recognition and dimensionality reduction.

StarStarStarStar

Genetic Algorithms

StarStarStarStar

Optimization and search algorithms based on the principles of genetics and evolution. Applied in feature selection and optimizing parameters for other techniques.
