get_events_matrix: Generates events matrix for selected events

In alan-turing-institute/DetectorChecker: A package for analysing pixel damage in CT Scanners

Description

Generates events mask (a matrix with pixels as 0 and events as 1) indicating if a pixel is in an event as calculated by find_clumps(detc) Note that the parameter incl_event_list is a list of integers from 1-8. For all events this would be list(1,2,3,4,5,6,7,8). The integer values declare which damage events to include: 1=singletons, 2=doublets, 3=triplets, 4=larger clusters, 5=upper horizontal lines, 6=lower horizontal lines, 7=left vertical lines, 8=right vertical lines

Usage

get_events_matrix(detector, incl_event_list = NA)

Arguments

detector	Detector object
incl_event_list	a list of events to be included

Value

Events matrix

Examples

# Create a detector
detector_pilatus <- create_detector("Pilatus")
# Load a pixel matrix
file_path <-  system.file("extdata", "Pilatus", "badpixel_mask.tif",
                         package ="detectorchecker")
detector_pilatus <- load_pix_matrix(
 detector = detector_pilatus, file_path = file_path)
# Identify events
detector_pilatus <- find_clumps(detector_pilatus)
# Get events matrix
get_events_matrix(detector_pilatus)
