This function analyzes image data to determine rotation based on tape coverage, assuming more tape is present on the upper side of the tube.
Usage
estimate_rotation_center(
img,
tape.brightness = 0.66,
extra.rows = 100,
search.area = 0.45,
tape.quantile = 0.98,
nclasses = 3,
select.layer = NULL
)Arguments
- img
Input image as raster, file name, or array
- tape.brightness
Brightness threshold for tape detection (0-1)
- extra.rows
Additional rows to add for analysis
- search.area
Proportion of image to analyze (0-1)
- tape.quantile
Quantile used to align brightness with tape (0-1)
- nclasses
Number of classes for pixel clustering
- select.layer
Integer. Specifies which layer to use if the input is a multi-band image. Default is `NULL`.
