Methods

Convert(IOutputArray)

Converts objects array from internal representation to standard vector.

public Rectangle[] Convert(IOutputArray objects)

Parameters

objects IOutputArray

Objects array in internal representation.

Returns

Rectangle[]

Resulting array.

DetectMultiScale(IInputArray, IOutputArray, Stream)

Detects objects of different sizes in the input image.

public void DetectMultiScale(IInputArray image, IOutputArray objects, Stream stream = null)

Parameters

image IInputArray

Matrix of type CV_8U containing an image where objects should be detected.

objects IOutputArray

Buffer to store detected objects (rectangles).

stream Stream

Use a Stream to call the function asynchronously (non-blocking) or null to call the function synchronously (blocking).

DisposeObject()
