calculate_area()

float util.Util.calculate_area ( np.ndarray points )

static

Calculates area from given unordered coordinate points, representing the coordinates of a quadrilateral.

Parameters

points

Corners of the quadrilateral

Returns

The area of quadrilateral

match()

np.ndarray util.Util.match ( Union[cv2.BFMatcher, cv2.FlannBasedMatcher] matcher, KDTuple kd_left, KDTuple kd_right, float threshold = 0.75 )

static

@brief Performs a match between two KDTuples
Performs a KnnMatch between kd_left.descriptor and kd_right.descriptor.
Filters out the bad matches and returns the good matches as an np.ndarray

@param matcher Matcher object
@param threshold Filter threshold. Defaults to 0.75

@return Good matches

static

Applies a mean shift to given image.

Parameters

image	Image to apply mean shift
dest_mean	Destination mean

Returns

Mean shifted image
