  2. Turtle graphics - Wikipedia

    en.wikipedia.org/wiki/Turtle_graphics

    Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.

  3. Object detection - Wikipedia

    en.wikipedia.org/wiki/Object_detection

    Objects detected with OpenCV's Deep Neural Network module (dnn) by using a YOLOv3 model trained on COCO dataset capable to detect objects of 80 common classes. Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos.

  4. Soft sensor - Wikipedia

    en.wikipedia.org/wiki/Soft_sensor

    Soft sensor or virtual sensor is a common name for software where several measurements are processed together. Commonly soft sensors are based on control theory and also receive the name of state observer. There may be dozens or even hundreds of measurements.

  5. Logo (programming language) - Wikipedia

    en.wikipedia.org/wiki/Logo_(programming_language)

    The first working Logo turtle robot was created in 1969. A display turtle preceded the physical floor turtle. Modern Logo has not changed very much from the basic concepts predating the first turtle. The first turtle was a tethered floor roamer, not radio-controlled or wireless. At BBN Paul Wexelblat developed a turtle named Irving that had ...

  6. Sensor - Wikipedia

    en.wikipedia.org/wiki/Sensor

    A chemical sensor array is a sensor architecture with multiple sensor components that create a pattern for analyte detection from the additive responses of individual sensor components. There exist several types of chemical sensor arrays including electronic, optical, acoustic wave, and potentiometric devices.

  7. Corner detection - Wikipedia

    en.wikipedia.org/wiki/Corner_detection

    To improve the corner detection ability of the differences of Gaussians detector, the feature detector used in the SIFT [20] system therefore uses an additional post-processing stage, where the eigenvalues of the Hessian of the image at the detection scale are examined in a similar way as in the Harris operator. If the ratio of the eigenvalues ...

  8. Cycle detection - Wikipedia

    en.wikipedia.org/wiki/Cycle_detection

    In computer science, cycle detection or cycle finding is the algorithmic problem of finding a cycle in a sequence of iterated function values.. For any function f that maps a finite set S to itself, and any initial value x 0 in S, the sequence of iterated function values

  9. Electro-optical sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-optical_sensor

    An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output. An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively between circuits ...
