FIND Barcode on .jpg files.

Program can be written in any language: JAVA, C, .NET Important here is WORK DONE, FAST and reliable, no matter witch language is used. Pgm must read .jpg images on a given folder. Each image contain just 1 barcode, besides other elements. Every image will be grayscale, 300dpi, scanned A4 page. Pgm must generate a .TXT file where each line will come with the NUMBER represented on each image. JUST THIS. So, supose that some folder has 3 images, named [login to view URL], [login to view URL] , [login to view URL] And supose barcode on first one is 5678 , second is 779988 and third is 1234567890 So, output file must be: [login to view URL] [login to view URL] [login to view URL] IMPORTANT RULES: 1- output must be a .TXT file named [login to view URL] generated on same folder where images are located 2- each line must contain interpreted barcode (15positions), followed by a '-' and the relative filename+extension (absolute accepted as well) 3- there will be only 1 barcode to be interpreted on each image 4- If NO barcode is located, or the barcode is unreadable, the first 15 positions of output line must contain zeroes. 5- if output .txt file already exists, it can be overwritten without warning. 6- pgm must be as fast as possible 7- pgm must show witch image is been processed (can be in raw mode, cmd window mode, anything that SHOWS pgm running. 8- if NO BARCODE is located, or image is corrupted, or barcode is not readable, the correspondent line must come this way: '000000000000000-name_of_image' 9- pgm CAN NOT HANG, in any circunstance. I attached some images for your testing.
