More tiff learnings

First, the acknowledgements:

Joaquim Luis 's cvlib_mex
and
MATLAB's rtifc.c code (its a utility that uses tifflib to read tiff images)

The problem:

Read many tiff images at a time, while applying a filter on each frame.
It was taking for ever to do this in MATLAB. Essentially I was reading the images in the tiff file in a loop, and then applying a mean filter on each image. It was a real pain - there were 1 GB's worth of image data (about 5000 frames) in each file and using MATLAB's native code was impracticle.

The solution:

I hacked the rtifc.c code to write tiffread_filter.c This essentially reads a grayscale image, n images at a time and filters each.

I used tifflib and opencv for this project. To compile I used gnumex. What I wanted to share here is the compile file. This is inspired from Joaquim Luis make file. Here is my version

function compile2()
% complie the tiffread file
%
% Adjust for your own path
INCLUDE_CV = 'C:\progra~1\OpenCV\cv\include';
INCLUDE_CXCORE = 'C:\progra~1\OpenCV\cxcore\include';
LIB_CV = 'C:\progra~1\OpenCV\lib\cv.lib';
LIB_CXCORE = 'C:\progra~1\OpenCV\lib\cxcore.lib';
INCLUDE_TIFF = ['"' pwd '\tifflib\include' '"'];
LIB_TIFF = ['"' pwd '\tifflib\lib\libtiff.lib' '"'];

% -----------------------------------------------------
include_cv = ['-I' INCLUDE_CV ' -I' INCLUDE_CXCORE ' -I' INCLUDE_TIFF];
library_cv = [LIB_CV ' ' LIB_CXCORE ' ' LIB_TIFF ];

if (ispc)
    opt_cv = '-O -DWIN32 -DDLL_CV110 -DDLL_CXCORE110 -DDLL_LIBTIFF3';
else
    opt_cv = '-O';
end

cmd = ['mex -v tiffread_filter.c' ' ' include_cv ' ' library_cv ' ' opt_cv];
eval(cmd) 

ABC Of Bengali

A is for Awpheesh (as in Office). This is where the average Kolkakattan goes and spends a day hard at work. And if he works for the 'West Bengal Gawrment' he will arrive at 10, wipe his forehead till 11, have a tea break at 12, throw around a few files at 12.30, break for lunch at 1, smoke an unfiltered cigarette at 2, break for tea at 3, sleep sitting down at 4 and go home at 4:30. It's a hard life!


B is for Bhision. For some reason many Bengalis don't have good bhision. In fact in Kolkata most people are wearing spectacles all the time.


C is for Chappell (as in Greg). Currently, this is the Bengali word for the Devil, for the worst form of evil. In the night mothers put their kids to sleep saying, 'Na ghumaley Chappell eshey dhorey niye jabe.' (If you don't sleep, Chappel will come and take you away!!)

D is for Debashish or any other name starting with Deb. By an ancient law every fourth Bengali Child has to be named Debashish. So you have a Debashish everywhere and trying to get creative they are also called Deb, Debu, Deba with variations like Debanik, Deboprotim, Debojyoti, etc. thrown in at times.


E is for Eeesh. This is a very common Bengali exclamation made famous by Aishwarya Rai in the movie Devdas. It is estimated that on an average a Bengali, especially Bengali women, use eeesh 10,089 times every year. 'Ei Morechhey' is a close second to Eeesh.

F is for Feeesh. These are creatures that swim in rivers and seas and are a favourite food of the Bengalis. Despite the fact that a fish market has such strong smells, with one sniff a Bengali knows if a fish is all right. If not he will say 'eeesh what feeesh is theesh!'

G is for Good name. Every Bengali boy will have a good name like Debashish or Deboprotim and a pet name like Motka, Bhombol, Thobla, etc. While every Bengali girls will have pet names like Tia, Tuktuki, Mishti, Khuku, etc.

H is for Harmonium. This the Bengali equivalent of a rock guitar. Take four Bengalis and a Harmonium and you have the successors to The Bheatles!

I is for lleesh. This is a feeesh with 10,000 bones which would kill any ordinary person, but which the Bengalis eat with releeesh!

J is for Jhola. No self respecting Bengali is complete without his Jhola. It is a shapeless cloth bag where he keeps all his belongings and he fits an amazing number of things in. Even as you read this there are 2 million jholas bobbling around Kolkata- and they all look exactly the same! Note
that 'Jhol' as in Maachher Jhol is a close second

K is for Kee Kaando !. It used to be the favourite Bengali exclamation till eeesh took over because of Aishwarya Rai (now Kee Kando's agent is trying to hire Bipasha Basu).

L is for Lungi - the dress for all occasions. People in Kolkata manage to play football and cricket wearing it not to mention the daily trip in the morning to the local bajaar. Now there is talk of a lungi expedition to Mt. Everest .

M is for Minibus. These are dangerous half buses whose antics would effortlessly frighten the living daylights out of all James Bond stuntmen as well as Formula 1 race car drivers. M is also for Maunkey Cap and Muphler!!

N is for Nangto. This is the Bengali word for Naked. It is the most interesting naked word in any language!

O is for Oil. The Bengalis believe that a touch of mustard oil will cure anything from cold (oil in the nose), to earache (oil in the ear), to cough (oil on the throat) to piles (oil you know where!)

P is for Phootball. This is always a phavourite phassion of the Kolkattan. Every Bengali is born an expert in this game. The two biggest clubs there are Mohunbagan and East Bengal and when they play the city comes to a stop.

Q is for Queen. This really has nothing to do with the Bengalis or Kolkata, but it's the only Q word one can think of. There's also Quilt but they never use them in Kolkata.

R is for Robi Thakur. Many nany years ago Rabindranath got the Nobel Prize. This has given the right to all Bengalis no matter where they are to frame their acceptance speeches as if they were directly related to the great poet and walk with their head held high. This also gives Bengalis the
birthright to look down at Delhi and Mumbai and of course 'all non-Bengawlees' ! Note that 'Rawshogolla' comes a close second !

S is for Shourav. Now that they finally produced a genuine cricketer and a captain, Bengalis think that he should be allowed to play until he is 70 years old. Of course they will see to it that he stays in good form by doing a little bit of 'joggo' and 'maanot'.

T is for Trams. Hundred years later there are still trams in Kolkata. Of course if you are in a hurry it's faster to walk.

U is for Aambrela.. When a Bengali baby is born he is handed one.

V is for Bhaayolence. Bengalis are the most non-violent violent people around. When an accident happens they will fold up their sleeves, shout and scream and curse and abuse, 'Chherey De Bolchhi' but the last time someone actually hit someone was in 1947.

W is for Water. For three months of the year the city is underwater and every year for the last 200 years the authorities are taken by surprise by this!

X is for X'mas. It's very big in Kolkata, with ParkStreet fully lit up and all Bengalis agreeing that they must eat cake that day.

Y is for Yesshtaarday. Which is always better than today for a Bengali (see R for Robi Thakur).

Z is for Jebra, Joo, Jipper and Jylophone..
