__init__()

def __init__	(		self,
			tau = 10,
			theThreshMatch = 0.5
	)

@brief  Constructor for the puzzle piece sift class.

Args:
    tau: The threshold param to determine similarity for SIFT feature.
    theThreshMatch: The threshold to determine match (0-1).

Member Function Documentation

compare()

def compare	(		self,
			piece_A,
			piece_B
	)

@brief  Compare between two passed puzzle piece data.
See https://opencv24-python-tutorials.readthedocs.io/en/latest/py_tutorials/py_feature2d/py_matcher/py_matcher.html
and https://scikit-image.org/docs/dev/auto_examples/transform/plot_matching.html

Args:
    piece_A: A template instance saving a piece's info.
    piece_B: A template instance saving a piece's info.

Returns:
    Comparison result & rotation angle(degree) & other params.

Reimplemented from MatchSimilar.

kpFeaExtract()

def kpFeaExtract (   piece )

static

@brief  Compute sift features from the raw puzzle data.

Args:
    piece: A template instance saving a piece's info.

Returns:

    des: The sift descriptor.

process()

def process	(		self,
			piece
	)

@brief  Process the puzzle piece.

Returns:
    The processed feature.

score()

def score	(		self,
			yA,
			yB
	)

@brief  Compute the score between two passed puzzle piece data.

Args:
    yA: A template instance saving a piece's info.
    yB: A template instance saving a piece's info.

Returns:
    distance: The distance between the two passed puzzle piece data.

Reimplemented from Matcher.
