Required Methods

Provided Methods

Detects edges in a grayscale image and prepares them to detect lines and ellipses.

Parameters
  • src: 8-bit, single-channel, grayscale input image.

returns Edge Image prepared by detectEdges() function.

Parameters
  • dst: returns 8-bit, single-channel output image.

returns Gradient Image prepared by detectEdges() function.

Parameters
  • dst: returns 16-bit, single-channel output image.

Returns std::vector<std::vector> of detected edge segments, see detectEdges()

Detects lines.

Parameters
  • lines: output Vec<4f> contains the start point and the end point of detected lines.

Note: you should call detectEdges() before calling this function.

Detects circles and ellipses.

Parameters
  • ellipses: output Vec<6d> contains center point and perimeter for circles, center point, axes and angle for ellipses.

Note: you should call detectEdges() before calling this function.

this function is meant to be used for parameter setting in other languages than c++ like python.
