Feature (computer Vision)

Feature (computer Vision)

In computer vision and image processing the concept of feature is used to denote a piece of information which is relevant for solving the computational task related to a certain application. More specifically, features can refer to

  • the result of a general neighborhood operation (feature extractor or feature detector) applied to the image,
  • specific structures in the image itself, ranging from simple structures such as points or edges to more complex structures such as objects.

Other examples of features are related to motion in image sequences, to shapes defined in terms of curves or boundaries between different image regions, or to properties of such a region.

The feature concept is very general and the choice of features in a particular computer vision system may be highly dependent on the specific problem at hand.

Famous quotes containing the word feature:

    Columbus stood in his age as the pioneer of progress and enlightenment. The system of universal education is in our age the most prominent and salutary feature of the spirit of enlightenment, and it is peculiarly appropriate that the schools be made by the people the center of the day’s demonstration. Let the national flag float over every schoolhouse in the country and the exercises be such as shall impress upon our youth the patriotic duties of American citizenship.
    Benjamin Harrison (1833–1901)
