In matiasb/biOps: Image processing and analysis

Description

This function does edge detection using the Canny algorithm.

Usage

imgCanny(imgdata, sigma, low=0, high=-1)

Arguments

imgdata	The image
sigma	The standard deviation used for the gaussian smoothing convolution
low	The lower threshold for hysteresis
high	The higher threshold for hysteresis

Value

return an imagedata object

Note

If not specified, the low and high parameters are estimated based in a histogram of the image.

Examples

	## Not run: 
		x <- readJpeg(system.file("samples", "violet.jpg", package="biOps"))
		y <- imgCanny(x, 0.7)
	
## End(Not run)
