A Hard Day's Night... well yesterday =).

I have only a couple of class this week, I was coding a lot of our library system, I hope to start some tests this week and finish the borrow books part in this weekend.

A lot of troubles with the administration of my faculty; it's a place full of wolves trying to sink you; I heard the comment of a teacher which was asking 'favors' in order to help you to take more courses, because she is a 'very good friend' of our academic secretary.

Following the burocracy and corruption; our principal faculty say that we send our troubles about the inscription to the university main departments (this due the teacher; and because we were really mad because she left enter before the inscription to other fellows of laboratory departments; she said that wasn't ordered from she... it was from the university... see to believe it).

And finishing the sad news, a new attempt to reduce the internet bandwidth used in the unversity we got a proxy... it will cost us about $1k or $2k (almost one year ago they tried put the proxy, but I think the cost weren't affordable for the university ... about $50k), of course we cannot get some fun or even post my thoughts from there... Look what is a 'Malicious site": http://www.gcossio.org, of course PHP could be Malicious but only to the MS eyes =).

I tried an algorithm I see on the net about enhancement using the edges of an image (the laplacian and the sobel), you can see the images (using the famous lenna, which I don't know it was taken from a playboy magazine =D):

The original picture:


The laplacian


Sobel:


Laplacian * Sobel


Final, Adding the original with the last operation (but reduced the bright to the half):


I've noted a lot of errors in jpg images (I don't know if was the PIL library), because what only enhance is the noise of the square segmented image...
