pixel values of an edge image (canny algorithm)
Hi
I simply wish to know what does the EdgeImage pixels getting calling "getEdgeImage()" method in the Canny algorithm founded in this forum, mean.
I print the values for each pixel in this way:
cannyObj.process();
Image edgeImg = cannyObj.getEdgeImage();
...........
pixels = cannyObj.image2pixels(edgeImg);
iw = edgeImg.getWidth(null);
ih = edgeImg.getHeight(null);
System.out.println(" EDGE IMAGE PIXELS");
for (int i = 0; i<iw*ih ; i++)
System.out.println(pixels><i>);
(I've substiuted quad parenthesis with angular one due to problems with html code of this post )
obtaining an array filled with values equals to 255 or 0, and nothing else.
Can anyone tell me what do these array values mean?
To implement my algorithm (dual active contours for shape extraction) I need to find a high gradient value........
thanks very very much in advance, to anyone who will help me!!
(please, help me :p)
