Azzam bakal jadi tahfiz



Alhamdulillah, ini adalah salah satu usaha yang baik, iaitu mengajar anak2 mengenal huruf Al-quran.
Alhamdulillah, azzam kini telah berjaya menghafal and recognize huruf2 al-quran dengan baik. tak caya, tanyalah dia:D

what's edge detection?

Huh! Today is the most boring day I ever had. You might ask why…
Well… I couldn’t give a good focus on my research, however, my reviva will be sooner….waaaa….what happened to meeee?? Arghhhhhhhhh…
I told my hubby that I couldn’t study well at the office today, therfore I request his permission to study at home. Heh! No need to worry about azzam as we sent him to a friend of mine. And of course I pay her to take a good care of azzam. Nothing in this world are free of charge, except the air that we used to breathe. Thanks God (ALLAH) for everything that you gave me.

Ok, I planned to finish up my future plan, but I’m not in the mood to do that. Thus I read something about edge detection. I’ve been thinking that I should write something about it, at least it shows that I do have a good understand besides; I could improve my writing skills, hehehhe…

Ok… what to you know about edge detection? It’s easy; it is a method of detecting edge. What is edge? Well, some might say such as boundaries of objects and some might say a line that shows a difference between two things. Err.. I shouldn’t say more, but I do believe everyone knows what edge is. But how does a computer detect edges? Note that computer even though they are very useful but they are not as clever as human being.

Now, try to think in what situation that edges might occur?

Come up..think first…

Lazy to think? Or don’t have nuch time to think?
Hehhee
Ok, edges often occur at points where there is a large variation in the luminance values in an image. Agree? Not agree, that tell me what you think…

In computer vision, edge detection is traditionally implemented by convolving the signal with some form of linear filter, usually a filter that approximates a first or second derivative operator. An odd symmetric filter will approximate a first derivative, and peaks in the convolution output will correspond to edges (luminance discontinuities) in the image. An even symmetric filter will approximate a second derivative operator. Zero-crossings in the output of convolution with an even symmetric filter will correspond to edges; maxima in the output of this operator will correspond to tangent discontinuities, often referred to as bars, or lines.

Opss… I think I should continue doing what I really planned for today. Well sorry if you are not satisfied with my article as there seems to be continue ( subject to my laziness or not, heh!)

A Clever Trick!

This morning, when i woke up to pray Subuh, my 2 years old son, Azzam also woke up and said, lapar nasi which means i'm hungry, i want to eat rice. Unfortunately, it will be a bit late if i have to cook rice for him as he needed to eat now. Therefore, i gave him bread an biscuits, but he refused. He still wanted to eat rice, and persue me to go to the kitchen. I told him, ok, show me what you really want. I let him down but he lies down and cry. I had enough, as the problem for me is, i haven't pray for Subuh and it's already 7 o'clock. I went to the bath, and took wuduk. Outside of the bath, azzam still crying and shouting ummi, ummi...
Just as i went out the bathroom, my dear son put his finger near the door and close the door just like his finger was tercepit kerana pintu. Heh! buat2 kesian le , pandai betul anak ummi berlakon, tangan tercepit...kasihanilah daku....
