The megapixel myth

A few month back someone ask me what camera he should buy. His requirement was to have at least 7 mega pixel camera. I had taugh time explaning to him that image resolution(number of pixel) has little to do with image quality. I don't know which camera he brought. To me a 3 mega pixel is enough for daily used unless am trying to print a wall size picture.

There are many people who have the same perception about mega pixel.Let me try to explain why megapixel has nothing to do with picture quality.

Pixel:
Pixel is the smallest element representing a picture. Pixel stand for picture element. They are arranged horizontally and vertically.






Megapixel:
Megapixel (pixel count) is the multiplication of horizontal pixel with the vertical pixel. So a 3 MP will have
2,048 (horizontal) x 1,536 (vertical) pixels, or 3,145,728 pixels. Megapixel are a square function so a small difference in megapixel are unimportant. A 40% increase in horizontal pixel double the pixel count. So a double pixel count increase the real horizontal pixel by 40%.

Image Resolution:
Image resolution is how much pixel are stored horizontally and vertically in a storage medium. A 3 MP camera will have 2048 pixel horizontally and a 14 MP camera will have 4500 pixel. The vertical pixel are much lower. There is no much difference between the number of pixel stored.

Print Resulution:
Print resolution how much pixel you have per inch in the print paper. Most print will have 300 dpi (dot per inch). This did not have anything to do with the camera.


The Myth:

The myth that a higher megapixel camera has better quality then a lesser megapixel camera was created by camera makers. They used is because its easy to increase the megapixel. A 40% increase in linear pixel double the megapixel.
Manufacturer tend to squeeze a large pixel in a small image sensor, which tend to degrade the pixel quality.So more important then megapixel is the pixel quality. A more sensitive high quaity image sensor with lower megapixel will give better image then a higher megapixel.










NB: if you are interested in buying my camera let me know hehehehe

Can engineers be 'Touchy feely'?

Can engineers be 'Touchy feely'? Apparently they can... says author Chetan Bhagat

I remember the incident - I was in a restaurant, and one girl in our group
was especially charming. So I, like any other male, tried to put on a
wooing act. You know the routine, a nanosecond extra eye contact, a few
more nods to whatever she says, and attempts to throw in those
one-liners which you know you wouldn't if she weren't there.
And it seemed to be working. She leaned forward when she spoke to me,
and every now and again, we'd have a small conversation of our own, separate
from our group. She laughed at my approach with the fork and knife, and
I teased her about her hair band, which had little teddy bears. Yes, we
were flirting. A while later, she asked me the question - what did I study?
I said engineering, without any particular meaning attached to it. And
then like a cold metal rail, she went stiff. My jokes weren't funny any more.

Her eyes wandered to everyone else. What was it?

Why? Why? Why?

Two days later, I still couldn't get over my great start that had
dissipated listlessly upon mentioning my education. Engineer? What was
wrong with that? My mom had wanted me to become one since I was five!
I had to call her. 'So what happened to you that day, hot and cold,
missie?' And then she said, trying to be nice, 'Well, it's just that I am
skeptical about engineers as friends. I don't know, they can be, you know, very
logical and everything... not very touchy feely'.

Not touchy-feely. Now what the heck did that mean? Well, she obviously
did not mean it literally, since girls don't really suggest that sort of
stuff, certainly not in the first meeting across the table. I guessed it
was something to do with feelings, sort of having an emotional side. The
stereotype being, the nerdy guy who sees relationships like laws of
physics, to whom love is just a bunch of chemicals going crazy in your
brain, and getting to know a person means obtaining their bio-data.

It's time to set the record straight.
It's true that a lot of what engineers study (and they end up studying
quite a lot), has to do with formulaes, laws and numbers. No matter how
hard we try, some of the vocabulary we read all day gets into our
language. So when my mother said, 'Are you getting married next year or
not?' I was liable to say, 'Well, at this moment in time, the
probability is relatively low,' and felt it was completely normal to say it. And
when my sister went sari shopping and couldn't explain the shade she wanted,
I told the shopkeeper the percentages of pink, orange and red in the sari.

Yet, ladies, I don't think we're bad at relationships, love and getting
to know people. We too, can be touchy-feely, as that is part of our
education as well. The reason for this is that most engineering students live in
the ultimate educator - boy's hostels. Now, let me explain how this plays
into this 'touchy-feely' thing. Relationships. Imagine eating, sleeping,
brushing your teeth, bathing (ok rarely this one) and partying with the
same people all the time. So, when you are kicking that bathroom door
down for the tenth time, or when you stand in line for 'gulab-jamuns' in the
mess, and when you are done with the vodka bottle and sharing all your
secrets, you know it is good practice. Yes, hostels maketh the man.

So, next time you are in a flirtatious situation with the techno types,
go on, flirt a bit more. Of course, I am biased towards my kind, but if you
find the conversation turning too geeky, just ask them, 'So, what were
your hostel days like?' and chances are, you'll see a heart behind the
calculator. Coming back to my missie, I thought of what would make me
win her over. Flowers... too cheesy. Music... don't know her taste (nor
trust mine). Teddy bears... don't even go there. Desperate for some good
lines, I just turned it right back at her. 'Yes, I know what you are saying
about engineers. The thing is, unless people with depth like you start hanging
out with us, we won't get any better. Can you meet me some time for some
touchy/feely... oops, I mean coffee/tea?' She giggled. When they giggle,
you have won. Hence proved.

Sugar in the tea

I used to drink tea in office with friends. The usual cup of tea which i used to drink include a spoon of sugar, two tea bags, milk powder and water.
The other day i thought i will drink my tea without milk and sugar. The test was not what i expected, it was bitter and i couldn't swallow it. I have to add sugar to make it sweet.

The tea bag give color to the tea. It give good aroma. By itself it did not give any test to the tea.
Sugar give test to the tea. It make the tea complete. It did not add anything to the appearance to the tea.

In life we could be like tea bags which give color to the tea but test bitter or we could be like the sugar which is invisible
but make the tea sweet.

We can be like the sugar in the tea and make the life of people around us sweet. We don't need to be the most visible part of someone life. We could do it without being visible like the sugar in the tea.

Four years of Professional life

I have never imagine i'll be staying in the same company for four years.
On 15th july 2007 i completed four years of my professional life hear at Atrenta India Pvt (Ltd).
What more can i say then thanking God for guiding me through these years.

I graduate from Delhi College of Engineering in Electronic and communication in june 2003.
I join Atrenta on the 15th of july 2003 as a software engineer. In the four years of my professional life
i have learn lots of things, met different people and visited places i never imagine i'll see.

I dont know why i stay in the same company for fours years while people move on within a year.
It could be the kind of work i did here, it could be the independence i get working here. I came to office whenever i want.
Nobody bother me unless i dont complete on dateline.

In four years i have move from software engineer to senior software engineer and now to lead engineer. I have got
offer from telecommunication consultant india (PSU) which i refuse. The reason i didnt join is i dont like the work.

I thank God, friends and my mentor here at Atrenta for making my stay such a pleasurable experience. I hope to get more experience in future.

God's Plan

For the past few week, i have gone through one of the most difficult phase of my life.
I am no the first one to experience those but there are friends who pray for me, who support me in
my difficult times.

Because of God help, i am able to overcome all my trouble. He made realize that He has a better plan for me.
And i am really thankful to God and the friends he gave me. I never had such confident in life, i'm more happy then before.

Last night (4th june 2007, 10:56 pm to be precise ), i got the answer which i always want to hear. It is something i always wanted to hear, but never expect. When i began to analyze how thing unfold, i realize that it was God plan that i have
to go through all those trouble. No i thank God for the work he did in my life and the joy he give me.
I give thanks to God and to everyone who make all these things possible.

"All things work together for good for those who love God'' (Rom 8:28)
