fit_gaussian2d(thresh=0.5, cbox=[[0, 0], [0, 0]], **kwargs)

Fit a 2D Gaussian function to the image data, feature update: can specify a box to fit the gaussian function

Parameters:

  • thresh (float, optional) – threshold to limit the fit region. Defaults to 0.5.

  • cbox (list, optional) – the range to specify the bounding box, [[x0,x1],[y0,y1]], default is no bounding. Defaults to [[0,0],[0,0]].

Returns:

fitting results
