Shape representation as curve
hi,
as seen on the image, i need to represent my hand shape as a time series curve, is there any available method that can provide me that easily.
PS: EDIT :
time-series representation, the start point of this curve is determined by RANSAC.
thanks for any comment and suggests..
EDIT : The angle is denotes horizontal axis denotes
the angle between each contour vertex and the initial point relative relative
to the center point, normalized by 360degrees360 . The vertical axis
denotes the Euclidean distance between the contour vertices and
the center point, normalized by the radius of the maximal inscribed
circle.
