At Newcastle! - Part Three

Hello everybody,

This blog has been inactive for quiet few months now and I thought it's by time I publish some news. I've been in touch with some of you, filling you in on what I've been up to so feel free to skip on the parts you know.

Many things have happened since October. After spending some time here I realized that keeping a record of my life in this place would be a far more difficult job that I imagined. I've been through a vast number of experiences; academically, socially and otherwise. It didn't take me long to realize that am probably going through the most interesting change in my life.

At the moment, am doing the second semester of my degree program. The first semester was very interesting in terms of subjects, lecturers and schedule. I enjoyed every moment of it, excluding the Christmas vacation when everybody here went back to enjoy the holidays with their families and I was left freezing :P

Despite the stacked schedule, I've been to a number of places during the first semester; notably York and Edinburgh! The latest trip to Edinburgh was magnificent in every aspect! Below are pictures of Edinburgh ...



Some of Edinburgh's Castle ...



and more of Edinburgh from the top of the castle ...

The second semester is going great so far. The courses am doing now are even more interesting than those I did during the first semester. I must say I so much enjoy doing my masters and peruse my studies in gratitude to the chances that brought me here.

Apart from my university, I get to do a whole lot of activities whenever I have the time. I can say my lifestyle has drifted considerably during my stay here. I find myself doing things I never thought I'd be capable of, also enjoying things that never made sense to me ... unbelievable!

Am also adoring the technology available at hand here. Everything starting from life at campus, government work, paying the bills, shopping and down to the simplest things such looking for a place to enjoy a Friday evening is only few clicks away.

The weather in Newcastle is fairly more pleasant than Amman. Although it can get very cold in some days, I still find it more convenient to cope with on contrast to the ridiculously-rapid climate changes in Amman!

Below are photos I've taken for my university during the recent snowfall ...



My friends in this place are adorable! Despite our different cultures, backgrounds, and interests, we still manage to enjoy each others' company and chill like life-time friends. I never bonded with anybody so firmly within months of meeting them. It is really hard to imagine parting ways with them.

Next week I'll be in London to spend a couple of days with the international students society. Chances are I might have something interesting to post about by the time I get back ...

If not ... see ya in some months :P

At Newcastle! - Part Two

Sorry for the delayed post guys! Time passes quickly here :)

I've been taking lectures for the past two weeks and was given some tasks to attend to during my free time. Many things are happening around here and posting about each is pretty much impractical.

To put my news in short, I moved into a shared flat with other International students (no more stays at hotels), met a number of friends, went on a couple of trips around Newcastle, and best of all: got a broadband Internet connection at my place! :D

Anyway, here are the details, starting with the incidents that were mentioned at the end of the previous post ...

An Evening at a Bar

Victor is a Spanish undergraduate student that I met during my first week at the university. He studies music at Newcastle and has invited me to a "Jam Night" at one of the local bars. He said that this bar holds Thursday evenings for jamming sessions and that many bands and solo artists perform there every week.

I made it there that Thursday and watched some bands perform; the evening was amazing! Anybody who wants to play would simply write their names on a chalkboard and wait for their turn. The songs  played ranged from country to some rock oldies, in addition to few originals.

Victor was expecting me to bring my guitar and jam along, but I told him I've been in town for a couple of days and it's not the right time ... yet ;)

Luckily, I got away with my vile no-drinking habit that evening with a simple "Sorry, I have a medical condition, I can't drink" :P

 The Tap

This happened during my first week too! I was heading someplace for dinner when a girl got almost ran over trying to cross the street to my side while yelling "Hey! Hey!".

She looked terrified and asked me if I can get her "a tap". I asked her "What's a tap?" and she acted out smoking a cigarette. I figured that a tap is slang for a cigarette! She said "I can't buy it because the guy at the supermarket thinks am a minor but my 18th birthday was just yesterday!".

Now in normal conditions, if somebody approaches me with such a proposition,  my reaction would range from simple refusal to beating them to death :P, but this girl really did crack me up! :D

So yes, I went to the supermarket and bought her a tap (how responsible). She gave me a pound and asked for the change but I didn't want to bother counting the pennies so I just told her "It's on me" and she was like "Ooooooh" and she hugged me :S

Of course I didn't let her go without some lecturing about the risks of smoking but she looked like a lost cause, or else I wouldn't have saved myself the hassle of denying her request.

Trip to Tynemouth

A couple of weeks ago I went with some friends to Tynemouth, a town at the mouth of the river Tyne at the east coast of England.

We passed by the historical Tynemouth Castle, a castle that stands on a high rocky cliff and is believed to have been there since the 10th century (making it 1000 years old). Anyway, embare7 wella el youm, it looked nothing more than a deserted bunch of stones to me :F



We also spent some time at King Edward's Bay.

The Tyne River

My favorite place in town is the Tyne river, I just can't get enough of it! It's great that this place is only a 15-minute walk from my university!

There are several bridges over the Tyne, some of which are high and expose wonderful scenery of the river, the town and the lands far beyond. The area around the banks of the Tyne (the quayside) has wonderful walks and is a perfect place for spending some moments of tranquility.


There are also some other places that are worth writing about but I'll leave these to other posts.

More news to followup later!

At Newcastle!

Hello everybody, this is to let you all know that I’ve arrived safely and am currently doing just fine in Newcastle, UK!

My trip to Newcastle was great. I had a five-hour stop at London’s reputable Heathrow airport, one of the world’s largest airports, which was such a nice opportunity to look around. I’ve wandered for hours but couldn’t see but a tiny portion of the airport. Heathrow is so big that people use metros to travel from one terminal to another!

My flight to Newcastle was a little bit delayed so I arrived late, unpacked and fell to bed. I woke up the next morning and took a walk around, checking up the places and the routes. My WLAN-equipped mobile phone and Google Maps are really doing me a great service here; I can locate any place and determine the best route to it with only few clicks on my mobile phone! :D


 
Anyway, I’ve been staying in hotels ever since I arrived, looking for somewhere to stay while I finish my Masters. Today I finally signed a contract governing my accommodation for the next year; I’ll be staying in a shared flat with five other international students.

Newcastle is such a great place to live in; there are endless things that I envy the people here for; the weather is great, there are almost no traffic jams and there are many green spaces around.

The town structure is very well planned, organized and friendly for first-timers. The rules that administer this place are so sensible that breaking them will simply do nobody any good!

 
The town can truly be described as “International” because of the great population of International students, workers and residents. Everybody here is friendly because they all realize that they live in a city that brings together a large number of nationalities from all over the world. Even the town locals appreciate this unique feature of their city and are actually happy about having such a variety of people around.

Anyway, I still have a couple of interesting “incidents” that I want to tell you about, in addition to the university … oh the university! (needs a post on its own!) but I’ll leave these for the next posts!

Upcoming events …

Ghaith gets invited by a Spanish guy to a Thursday evening in a bar and he comes over. What happens?

Ghaith is wondering around in a desolate part of the city at night and a girl gets almost ran-over trying to get to him from the other side of the road while yelling “Hey! Hey!”. What does she want?

More 3D Scans

Next week will be our last in our training at KADDB. Our 3D Laser Scanner is now completed and we're adding the final touches. The scanner has undergone tremendous upgrades and is now performing way better than it used to last month.

To put it in short, during the past month we've managed to complete multiple viewpoint scanning and 3D mapping. The device can now automatically capture data from multiple views of the object and merge these sets of data to form a complete 3D model.

We've corrected serious bugs related to surface sampling. We've also programmed algorithms to compensate for inaccurate calibrations and instrument errors. Using these and some additional tweaks we've raised the maximum sampling rate to an amazing 6.66 samples/mm while cutting half the scan time!

The models we're producing now are extremely accurate and look amazing.

Take a look ...


The figures above show two point clouds of the Garfield toy. The cloud on the left is an example of what we were getting a month ago while the one on the right is an example of current scanner output. The new model is of much higher resolution and is completely noise free.

First of all, to help you visualize how our scanner now produces complete 3D models by scanning an object from multiple angles, have a look at these ...


The above models are for a violinist statue. They are actually point clouds, but are so dense that they look like 3D models even before reconstruction.

The cloud on the left has a lightning effect that will help you visualize what the model looks like. The cloud on the right is a special point cloud where data collected from each viewpoint has been represented by a certain color. There are four colors in this point cloud because it was formed by four different scans, each being from a different angle.

I've taken closeup captures on the violinist statue's face (which is smaller than 15cm x 10cm) to show you how accurate our scanner's resolution can be. The models below were constructed using only 25% of the maximum scanning resolution ...


One of the objects we scanned was an old wooden eagle statue. The produced model showed all object details including tiny carved regions ...


The high quality of the models we're producing reflect greatly in rendering.

Here are few shots:


In case you're wondering, that's a camel on the right ;)

The guys at KADDB were amazed by the results of this project.  We've been told that there is a good chance that our 3D scanner will be moved to their central research department where it will be allocated larger funding and continue to be worked on.

I have decided to build a separate web site giving the in-depth technical details for researchers. I will also provide some of the models we've produced and explain few ideas that make our scanner better than many others. The website, however, won't be available anytime soon because it's by time I have some rest now ;)
