Sentence examples for character contours from inspiring English sources

The modified direction feature (MDF) extraction technique builds upon the direction feature (DF) technique proposed previously that extracts direction information from the structure of character contours.

The size of the section is chosen as m=20, which is greater than or equal to the period of the ink tails on the character contours.

The character contour roughness of a laser printer is expected to be less than that of an inkjet printer because character contours originated from laser printers are smoother.

Initially, each character contour is divided into several segments.

Contour roughness is drawn from the character contour; it reflects the degree of roughness on the character contour and is mainly used for laser and inkjet printer identification.

This feature describes the degree of character contour roughness between the two printing techniques.

This process can be denoted as the character contour projection from 2-D contour to 1-D vector.

A projection is applied on the character contour to transfer the 2-D contour curve to a 1-D vector used to compute the contour roughness.

The edge searching method based on the binary image is applied to extract the character contour, and the coordinates of contour pixels are recorded in this process.

Due to these periodic tails or satellites, the character contour is rougher than in laser-printed and copied characters, and the value of contour roughness is higher for inkjet-printed characters.

For some brands and models, the period of the ups and downs can be observed in the character contour because the distance between two scanning traces is constant for a printer, and the distance between two tails is therefore the same.
