Place qPLMarr Data in Tabular Format

Description

qPLMTabulate casts data from the [u,v,3] array format of a qPLMarr object into a qPLMtab matrix.

Usage

qPLMTabulate(qPLMarr, low.pass = 5/256)

Arguments

qPLMarr	A qPLMarr object.
low.pass	A low-pass filter value (as an 8-bit grayscale level, 1-256) to remove noisy in-plane orientation data from low-theta pixels. Default is five.

Value

A [u*v,9] qPLMtab matrix, with columns (1) theta, (2) phi, (3-5) the Euclidean projection of theta and phi, (6-7) the [u,v] address of the pixel as an integer, and (8-9) the [u,v] position of the pixel in millimeters.
