boxes_to_spatial_polygons: Convert xml crown annotations into projected bounding boxes....

In weecology/NeonTreeEvaluation_package: Evaluate Individual Tree Segmentation Algorithms against Benchmark Data

Convert xml crown annotations into projected bounding boxes. In order to plot the annotations, they need to be projected and overlayed on RGB boxes

Description

Convert xml crown annotations into projected bounding boxes. In order to plot the annotations, they need to be projected and overlayed on RGB boxes

Usage

boxes_to_spatial_polygons(boxes, raster_object, project_boxes = TRUE)

Arguments

boxes	A data frame with xmin, xmax, ymin, ymax columns. Each row is a crown bounding box.
raster_object	A RGB raster to overlay annotations
project_boxes	Whether boxes need to be projected to utm from image coordinates (origin 0,0 top left)

Value

SpatialPolygons object of annotations

Examples

xml<-get_data("SJER_052","annotations")
annotations<-xml_parse(xml)
rgb_path<-get_data("SJER_052","rgb")
rgb<-raster::stack(rgb_path)
ground_truth <- boxes_to_spatial_polygons(annotations,rgb)
plot(ground_truth)
