pynrc.reduce.ref_pixels.channel_smooth_fft(im_arr, winsize=64)[source]¶

Channel smoothing using smooth_fft

Function for generating a map of the 1/f noise within a series of input images. The input images should show some clear noise structure for this to be useful. Uses M. Robberto smoothing algorithm.

One might prefer the channel_smooth_savgol or channel_smooth_butter functions due to their quickness.

Parameters

im_arr (ndarray) – Input array of images
winsize (int) – Window size chunks to break up
