Hi
Quick version: Web page gives 'gradients' in example, but 'gradients' not found in ocroscript. Long version: I see from http://ocrocourse.iupr.com/image-processing an example of the Canny edge detector. The sample program includes the command 'gradients': read_image_gray(byteimage,arg[1]) image:copy(byteimage) gauss2d(image,3.0,3.0) gradients(gradm,gradx,grady,image) I'm using the ocroscript that comes with ocropus-0.2: [EMAIL PROTECTED]:~/ocropus-0.2/ocroscript$ ocroscript -v OCRoscript (interactive) But gradients does not seem to be defined: [EMAIL PROTECTED]:~/Desktop$ ocroscript canny.lua ocroscript: canny.lua:11: attempt to call global 'gradients' (a nil value) stack traceback: canny.lua:11: in main chunk [C]: ? [EMAIL PROTECTED]:~/Desktop$ I looked for gradients in the .pkg files, but didn't find it. Looked around in the subversion server, particularly image.pkg, and didn't see anything there either. Is 'gradients' something that existed in a previous release? Is there an equivalent function in ocropus-0.2?
