Stats

kernel_points(image, point, step=1)

Returns coordinates of pixels in a square matrix of width 2*step, whose center is point

Parameters:

• image: ndarray (width, height)
• point: tuple (2,)
• step: int

Returns: tuple (n_points,2)

stats_preprocess(array, step)

Rounding angles to multiples, e.g. 0, step, 2*step, etc.

Parameters:

• array: list, ndarray (n,)
• step: int

Returns: array_copy, array_copy_set, dens_curve

gaussian(x, mu, sigma, amp=1)

ellipse(a, b, angle, xc=0, yc=0, num=50)

Returns coordinates of an ellipse constructed from given parameters. Center is (0,0) by default. Angle in radians, decreasing the angle denotes clockwise rotation of the ellipse

Parameters:

• a: float
• b: float
• angle: float, rad
• xc: float, center coord x
