Description:
The goal of this project has been narrowed and simplified.
This project needs to take several source images which are a series of panoramic photos, and merge them together into one large jpg.
We need a module or routine that will be called from within our own VB program. This module will accept the following variables:
1) The directory and filename for the output image
2) A 4 dimensional array of source images that contain
a) the directory and filename of the source image
b) the starting x cordinate in the output file for the source file
c) the starting y cordinate in the output file for the source file
d) the intensity of blurring to take place to soften the edges of the individual pictures (the blurring would start at the x cordinate. The intensity number would amplify the blurring to take place at the x-cordinate, and expand left/right as the intensity number increases. The blurring would decrease as it expands left/right to create a smooth transition)
Deliverables:
1) Working source code of all work done.
2) Complete ownership to all work purchased.
Platform:
Windows 2000
Must be 100% finished and received by buyer on:
Jan 31, 2003 EDT

Hi
Basing on my experience with image processing tasks I'm sure I can finish the job (way?) before the deadline.
The program will read each pair of jpeg files and then scan them vertically for matching (and overlapped) lines (there will be some sort of tolerance setting; most likely the comparison will be based on hue values of pixels, but this will be decided later after I've taken a look at some image samples).
You will not have to provide the exact value for number of overlapping pixels for every two images - specifying one common maximum and minimum *possible* values for all those thousands of images is usually enough.
The program will be written in C++ for performance reasons, and I'll also try to optimize the algorithm (I have a strong experience with algorithm optimizations, so you will not be disappointed with the program's speed).
I'll provide you with free 90 days of technical support (fixing bugs, if any are encountered, solving possible problems etc.) after the job is completed and accepted.
I don't want to set an unfair bid amount for your project, neither I want to estimate the time needed to finish it incorrectly, so before making my bid I'd like to take a look at some image samples. It won't take me long to make the decision, I'd just like to have an idea about what kind of images you've got (size, variations etc).
Don't hesitate to contact me if you have any questions.
Looking forward to hear from you.
Good luck,
Ivan

Hello, and Happy new Year!
I attached a demo of an ActiveX control that you can use in your Visual Basic program. No 3d-party libraries are required.
The control exposes 4 methods:
BOOL AddFile( file_path, x, y, blur ); (append new file for merging)
BOOL Merge( destination_file_path ); (merge appended files)
BOOL Reset(); (clear internal file data array - Merge calls this method automatically)
SetQuality( quality ); (set destination JPEG quality - not currently implemented)
It's written in C++ for performance reasons (and I'm sure you'll like the performance).
I took the liberty of slightly modifying your requirements to get rid of 4-dimensional array. Adding images separately allows more flexible error processing and improves code readability. Let me know if you don't like this change.
To use the object in your VB program you should:
1. Go to 'Project/References'
2. Click 'Browse' and browse for the JPEGMerge.dll
3. Make sure that 'JPEGMerge 1.0 Type Library' item in 'Available References' list is checked
4. Press OK
5. In your code, use something like:
--------
Dim Merger As New JPEGMerger
Merger.AddFile 'path_to_file1.jpg', x1, y1, blur1
...
Merger.AddFile 'path_to_fileN.jpg', xN, yN, blurN
Merger.Merge 'path_to_destination_file.jpg'
--------
Please note that this is just a demo version and blurring algorithm isn't fully tuned up yet. (currently blur value passed to AddFile is simply the amount of pixels to be included in blurring).
I processed some of your sample data with this control, the resulting jpeg is attached. The code used to produce the result was:
Dim Merger As New JPEGMerger
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p4_010810_104903.jpg', 350, 0, 5
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p5_010810_104923.jpg', 350, 3, 10
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p6_010810_104943.jpg', 350 * 2, 5, 5
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p7_010810_105004.jpg', 350 * 3, 7, 5
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p8_010810_105024.jpg', 350 * 4, 10, 5
Merger.AddImage 'D:\\RAC_JPEG\\bai_park48_c2_p9_010810_105045.jpg', 350 * 5, 13, 5
Merger.Merge 'D:\\RAC_JPEG\\result.jpg'
As you can see, it's nearly finished - fine-tuning the control won't take more than 2 days after you accept my bid.
Don't hesitate to contact me if you have any questions or wishes about control's functionality
Loking forward to hear from you.
Good luck,
Ivan
