  2. Random sample consensus - Wikipedia

    en.wikipedia.org/wiki/Random_sample_consensus

    Random sample consensus (RANSAC) is an iterative method to estimate parameters of a mathematical model from a set of observed data that contains outliers, when outliers are to be accorded no influence [clarify] on the values of the estimates.

  3. Hough transform - Wikipedia

    en.wikipedia.org/wiki/Hough_transform

    The Hough transform is a feature extraction technique used in image analysis, computer vision, pattern recognition, and digital image processing. [1] [2] The purpose of the technique is to find imperfect instances of objects within a certain class of shapes by a voting procedure.

  4. Randomized Hough transform - Wikipedia

    en.wikipedia.org/wiki/Randomized_Hough_Transform

    Hough transforms are techniques for object detection, a critical step in many implementations of computer vision, or data mining from images. Specifically, the Randomized Hough transform is a probabilistic variant to the classical Hough transform, and is commonly used to detect curves (straight line, circle, ellipse, etc.) [1] The basic idea of Hough transform (HT) is to implement a voting ...

    The American Sleep Apnea Association (ASAA) is a non-profit organization founded in 1990 by persons with sleep apnea, health care providers and researchers. [2] The association offers education and advocacy services to improve the lives of sleep apnea patients.

  6. Upper airway resistance syndrome - Wikipedia

    en.wikipedia.org/wiki/Upper_Airway_Resistance...

    In 2005, the definition of sleep apnea was changed to include patients with UARS by using RDI to determine sleep apnea severity. The diagnosis of UARS is based on findings on a polysomnogram . On polysomnograms, a UARS patient will have very few apneas and hypopneas, but many Respiratory effort-related Arousals.

  7. Scale-invariant feature transform - Wikipedia

    en.wikipedia.org/wiki/Scale-invariant_feature...

    Hough transform identifies clusters of features with a consistent interpretation by using each feature to vote for all object poses that are consistent with the feature. When clusters of features are found to vote for the same pose of an object, the probability of the interpretation being correct is much higher than for any single feature.

  8. Light therapy - Wikipedia

    en.wikipedia.org/wiki/Light_therapy

    Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.

  9. Obstructive sleep apnea - Wikipedia

    en.wikipedia.org/wiki/Obstructive_sleep_apnea

    For those with obstructive sleep apnea unable or unwilling to comply with first line treatment, the surgical intervention has to be adapted to an individual's specific anatomy and physiology, personal preference and disease severity. [112] Uvulopalatopharyngoplasty with or without is the most common surgery for patients with obstructive sleep ...
