More image processing with python and opencv
Friday, October 26th, 2007Continuing with the image processing with python I have done some experiments with the opencv wrappers for python.
Its easy to configure this wrappers in windows. What I did was:
>cd C:\Program Files\OpenCV\interfaces\swig\python
>c:\Python25\python.exe setup-for-win.py build
>c:\Python25\python.exe setup-for-win.py install
from opencv import highgui
from opencv import cv
win = ’showtime’
highgui.cvNamedWindow(win)
im = highgui.cvLoadImage(‘c:\image_file.jpg’)
highgui.cvShowImage(win,im)
highgui.cvWaitKey(10)
hope this works for you
python for image processing
Thursday, October 25th, 2007I am learning a bit about python programming. This programming language is becoming a popular scripting program inside oder programs such us arcgis. The most surprising thing for me is it increasing use in windows machines.
So I have decided to learn python. I have started with some easy functions from the python image library.
First I will read a pixel.
import Image
im= Image.open(“mytif.ti”);
pixel= im.getPixel((44,33));
print “And the pixel is!!: “, pixel
