We have some scanned images ... , which will have the grid of cells , each for one character.
we have to fetch each characters image and store it in specified folder.
1. the scan image will not be straight. so first we have to make it straight ( this will be the biggest part in programming )
2. then crop the image to outer blue boundary of table ( see image) and scale up or down to standard size.
3. now we have standard size image . so we just have to crop small parts of the image and save it as image file for individual character.
for scaling and cropping image together . you can use approach that ,
for each border of image ( i.e top , bottom , left and right )
( we are considerinf left side in this loop )
removing a singe row or column ( by using cropping ) from that sides until you encounter a blue colour in any of the pixel in that row or coulmn
once you encounter a pixel , check if its in upper half of that side or lower half . if its in upper half rotate image in clockwise direction . if in lower half rotate in anticlock wise direction.
again start processing that side and remove column untill you find borders blue color .
repeat this till you find that first column is having all blue color pixels ...
repeat this for all sides
this will give you image which is having nothing but just a table in its 100% area. then you have to scal and get the character wise image and store it in folder
see sample images below.
please contact for clarification.
we will not consider bids above $100
