Clustering by compression

TL;DR: The normalized compression distance (NCD) as discussed by the authors is a similarity metric that approximates universality based on the normalized information distance (NIC) metric, which was proposed by the authors of this paper.

Goal-directed evaluation of binarization methods

TL;DR: This paper presents a methodology for evaluation of low-level image analysis methods, using binarization (two-level thresholding) as an example, and defines the performance of the character recognition module as the objective measure.

A linear-time component-labeling algorithm using contour tracing technique

TL;DR: A new linear-time algorithm is presented in this paper that simultaneously labels connected components and their contours in binary images and extracts component contours and sequential orders of contour points, which can be useful for many applications.

Snakes : Active Contour Models

TL;DR: This work uses snakes for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest, and uses scale-space continuation to enlarge the capture region surrounding a feature.

Eigenfaces for recognition

TL;DR: A near-real-time computer system that can locate and track a subject's head, and then recognize the person by comparing characteristics of the face to those of known individuals, and that is easy to implement using a neural network architecture.
Book

Pattern classification and scene analysis

TL;DR: In this article, a unified, comprehensive and up-to-date treatment of both statistical and descriptive methods for pattern recognition is provided, including Bayesian decision theory, supervised and unsupervised learning, nonparametric techniques, discriminant analysis, clustering, preprosessing of pictorial data, spatial filtering, shape description techniques, perspective transformations, projective invariants, linguistic procedures, and artificial intelligence techniques for scene analysis.
