The present disclosure relates to a method of extracting and labeling connected elements in images, and more particularly, to a method of detecting connected elements formed as pixels are connected to one another in images and assigning label numbers thereto. A method of extracting and labeling connected elements of images of the present disclosure has the effect of improving productivity by quickly and effectively performing detection and grouping of connection element objects in an image and assigning label numbers thereto by using a small number of operations. A method of extracting and labeling connected elements of images of the present disclosure has an effect of accurately extracting and labeling connected elements without an error even when the shape of the connected elements of an image is complicated.

Method of extracting and labeling connected elements in images

Provided are a method and apparatus for detecting a pattern image, and more particularly, a pattern image detection method and a pattern image detection apparatus for effectively detecting a pattern of a template image from a target image. The pattern image detection method and the pattern image detection apparatus can provide an effect of quickly and accurately detecting the pattern of the template image from the target image while reducing the amount of computation for detecting the pattern of the template image.

Pattern image detection method

A geometric pattern matching method and a device for performing the method includes determining, by a geometric pattern matching device, information on reference geometric pattern contour points for a learning object on a learning image. The method can further include determining, by the geometric pattern matching device, information on detection object contour points for a detection object on a detection image, and performing, by the geometric pattern matching device, geometric pattern matching between the learning object and the detection object on the basis of the information on the reference geometric pattern contour points and the information on the detection object contour points.

USB dongle

A method and device for detecting connected pixels in a two-dimensional (2D) image having a plurality of pixels each having X-Y coordinates may compare an upper-row pixel included in a Yth row with a lower-row pixel included in a Y+1th row depending on a comparison condition, wherein Y is a positive integer, and wherein when a difference in X coordinate between the upper-row pixel and the lower-row pixel is one or less, the upper-row pixel and the lower-row pixel are determined to be positioned adjacent each other, and when the difference in X coordinate is two or more, the upper-row pixel and the lower-row pixel are determined to be spaced apart from each other and update an index map that defines a relationship between index numbers of adjacent pixels depending on the determination to set pixels with the same or associated index number in the same pixel group.
