openpiv_cxx.filters.intensity_cap

openpiv_cxx.filters.intensity_cap(img, std_mult=2.0, keep_dtype=True)

Set pixels above threshold to threshold.

Set pixels higher than calculated threshold to said threshold. The threshold value is calcualted by img_mean + std_mult * img_std.

Parameters:

• img (ndarray) – A two dimensional array containing pixel intenensities.

• std_mult (float) – Lower values yields a lower threshold.

• keep_dtype (bool) – Cast output to original dtype.

Returns:

img – A filtered two dimensional array of the input image.

Return type:

ndarray
