A simple command line tool for calculating spatial information for images based on Soble operator.
Warning: this tool is very alpha.
The command line tool calculates spatial information based on the Sobel operator. The
spatial information mean value (SImean) is printed to stdout.
Spatial information is defined as
SIr = sqrt(sX^2 + sY^2)
where sX and sY are output of the Sobel kernel.
SImean is defined as
(1 / pixel) * sum(SIr)
where pixel is the amount of pixels in the image.
Use
si <image>
from command line where <image> is the filename of the PNG or JPEG image to get SImean for.
Precondition: installed go 1.8.3
Clone the repository and type
go build si.go
go build msss.go
