Get projections and detrend

function [Y, p, R, CaliAli_options] = get_projections_and_detrend(Y, CaliAli_options)

Description

Process session data by detrending and computing projections.

This function processes video session data by applying detrending, removing background noise, and calculating projections such as blood vessels, neuron activity, peak-to-noise ratio (PNR), and correlation images.

Function Inputs:

Parameter Name	Type	Description
Y	3D array	Input video session data as a height x width x frames array.
CaliAli_options	Structure	Configuration options for processing, details in CaliAli_demo_parameters().

Function Outputs:

Parameter Name	Type	Description
Y	3D array	Detrended and background-corrected video data.
p	Table	Table containing projections: mean image, blood vessels, neuron projection, PNR, and a fused BV-neuron image.
R	Data range	Data range after detrending, used for normalization.
CaliAli_options	Structure	Updated options structure after processing.

Example usage:

[Y, p, R, CaliAli_options] = get_projections_and_detrend(Y, CaliAli_options);
