Why even bother making this complicated with VHDL and Matlab? You can do the whole thing quite simply in a shell script on Linux (or any other modern Unix variant) using the composite tool from the free ImageMagick package.
Since ImageMagick is also available for free on Windows, you could probably do it there too, although I suspect finding a scriptable scanner program might be a bit harder, like most stuff is on Windows .
hai friends...i am mahendarn..now i m doing m.sc electronics.now i am going do project about watermarking using FPGA..so kindly help me give idea about this projects.
hi ,
i am also doing same final year project in matlab.
my approach is using invisible watermarking based on space modification in the text.
i have made got code for convert text to image and convert it into 2d binary matrix .
now i have to find the lenght of each word in term of pixel and i noted that space always have 5 continues 1 in matrix.
for space between two lines there is 9 no of 1 and one letter consist of 9 zeros max in vertical direction so i have to store length of each word in separate array then using segmentation and using mean values of left and right word , i have to change space pixel.
this is my approach.
if you have any other approach then send me yours and if you can, please send me your code . I required it a lot.
hi,
along with this i am using one more approach called synonym substitution and i required how to embed wordweb in matlab in my code. After that i have to find a delegate for particular word and replace it along with a wector matrix which keep the record where i had inserted particular word.
