About

Hi, I'm Mohammad Shahiduzzaman (Zaman) from Bangladesh [1]. C/C++ is my favorite language, so I did most of academic projects in those except some DBMS project PHP. In professional life I worked with J2EE, so have a handy skill with that. I love solving participating and solving (though retired now) programming contest problems. My resume and some of my past works can be found at [2].

Google Summer of Code 2007

I'm applying for:

1. SoC2007_projects#Processing_of_very_large_images

Project Description

Goal: Allow the creation of arbitrary large panoramas by porting the core remapping routines of panotools/hugin to VIPS, so that panoramas of almost arbitrary size can be computed. Desired results of the project

   * VIPS operations that support the geometric and photometric (vignetting correction) transformations.
   * Standalone command line program that remaps images using these routines.
   * Program/script to convert panotools scripts to nip2 projects. 

Deliverables

• Write and add adequate VIPS operations to use for panotools. (for example for resampling).
  • comment: I skim through the code of VIPS and panotools core library. Understanding panotools code is bit hard and lacks programming documentation as compared to VIPS. So the details of this will be filled in the future.

• Build an application preferably in C++ which implements some useful part of panotools based on VIPS.

• write a conversion script (panotools script -> nip2 script/workspace).
  • Comment: I still have to gain complete familiarity of panotools and nip2 scripting. So more details will be added in future.

If time permits then -

• Compare performance and memory use with comparison to existing panotools code. (If this can be done then it will prove figuratively that the project worth being done.)

• Benchmarking for the developed multi threaded application. (may sound ambitious, but no doubt quite interesting, I'll love to get this done).

Project Schedule

• April 9 - Application selection

• Interim Period: Study and play hard with panotools core library and VIPS I/O system. Getting the

know how of panotools and nip2 scripting as well as internals. Fixed the detailed deliverables.

• May 28 - Begin coding, develop the required functions in VIPS.

• June 14 - 1 week for proper testing.

• June 20 - Develop the C++ application for some part of panotools based on VIPS.

• July 6 - 1 week for proper testing.

• July 13 - Started working on the script converter. (Allocated more time in this phase, because I

may have an academic exam in that time).

• August 1 - 1 week for testing.

• August 7 to 19 - Finishing touch and documentation.
