Vivian: Someone is putting stuff on our page... someone who doesn't do barcode recognition, nor is in our group... I think it's Group E since they have added the same picture on ours as well as theirs. If anyone sees any member of Group E, please tell them to stop messing with our wiki! The person in particular has the student number: 10033621.
Vivian: Anyway, Great work guys on our progress! It's great that we've succeeding in deciphering the image to the binary code. All we need to do is read the numerical code and figure out how to deal with noise.
Dilak: What about just removing it from our page, since thats not ours!!
Eric: (13/09/2006) The other program we face is how to locate a bar code from an image?
Cass: (13/09/2006 5:05PM) I had a picture up there before... what the hell happened to it!!! Will get make it again and put it up. As mentioned in our meeting during lab, we should do research on filters by next week.
Good work on getting the code working Eric!
Vivian (13/09/06): Great work team. We've successfully coded matlab to convert the barcode image into the numeric code! Took us a while, but we got there. What we've got to figure out now is how we're going to deal with the issue of noise as well as an inverted barcode. Also, in regards to the mysterious addition of a picture on our wiki, Team E has apologised.
Vivian (20/09/06): Hey Team, we have a 2 week "break" quite soon and I think that we should get a checklist of what we pretty much should do by the end of it. That way, we can be up do date and sort out any glitches in the last couple of weeks before deadline.
To do:
- noise reduction: algorithm, matlab code, research
- GUI
- any advantages and limitations to our design
Vivian (20/09/06): Today in lab, Dilak discovered that the barcode image Cass put online does not work. I shall post some more images online that we can test - a variation of the barcode we developed our code around, and the barcode Cass put on this wiki
Dilak (23/09/06) Today I tested our code for different UPC-A barcodes downloaded from the net.our code works only for some. in some bar code the the width of the white not equal to width of the black.
Vivian (27/09/06): I think we need to be careful of the barcode images we get. Comparing real-life images on everyday products as opposed to the images on the internet, there is quite a difference. In terms of the real-life ones, the width of the bars and spaces are near perfect. The ones on the net vary due to scanning procedures, etc. But one thing is for sure. They are imperfect. The only option now is what we want to do. We can see if we can scan our own images into the computer to see if that works. Otherwise we can also deal with the "noise" issue, including the distortion of barcode bar widths. OR we can ignore it and document it in our limitations section.
Eric(03/10/06): I have worked out a sample barcode scanning program. and i will explain and post up the result ASAP. Cheers~
Cass (16/10/06): After our discussion last week I realised that to continue the GUI we need to decide how to create the GUI. We can either use the GUIDE and callbacks or write it all ourselves. Both have pros and cons but since none of us have made much progress I thought I shouls make sure that we all knew what the options were.
I also got some barcodes but I will distribute them on wednesday cause they are big files.
Eric(01/11/06): Last fews things we have to do before we hand in program code: 1. Remove unused file. 2. Remove unused comment. Also, I have clean up all my part. Please make sure the last copy is a clean and correct one.
