Dear all,

Following a suggestion by Henrik Bengtsson I installed EBImage/biocondutor package. I also installed ImageMagick and GTK software because EBImage need it. After look at EBImage I find a function that compute Haralick texture on images. I tryed to run it with following simulated image, but I get error.

myimage<-as.Image(matrix(sample(100*100),nc=100)) image(myimage)

haralickMatrix(x=myimage,ref=myimage,nc=12)

> haralickMatrix(x=myimage,ref=myimage,nc=12)
Error in function (classes, fdef, mtable) :   unable to find an inherited method for function "haralickMatrix", for signature "Image", "Image"
>

Any suggestion are wellcome.

Kind Regards,

miltinho
