2013-03-14 15:59:08 +0100 | answered a question | Image processing Thank you this example works, but what about if my image is not Lena.png (I put that like example). If I put something like this: I=misc.imread(DATA+'myexample.png') and put the rest of Your code I got "TypeError: mat must be a Matrix or a two dimensional array". My image is color image so it's 3D. How I can easy convert to 2D? Thank you in advance! |
2013-03-14 14:39:31 +0100 | asked a question | Image processing Dear all, I have question about manipulating image in Sage. Here is some example. Img is now array with float elements. But I want to add some shapes on this image like circle, rectangle, polygon etc, but c=Circle, b=Rectangle and a=Polygon are object of some clases so if I want to do something like this show(img+c) or show(img+b) it is not allowed. Another question is: How I can put circle on my position (position is corner of image) because Img is array so I don't know where new row start. Is there some simple way to do this? Thank you in advance |
