Invisible Watermarking (Least significant bit Watermarking)
1. A raw bitmap image ‘A’ will be selected from the set of standard test images. Let this be the base image on which the watermark will be added.
2. A raw bitmap image ‘B’ will be selected from the set of standard test images. This will be the watermark image which will be added to the base image.
3. The most significant bit henceforth will be mentioned as MSB, of watermark image ‘B’ will be read and these will be written on the least significant bit, henceforth will be mentioned as LSB, of base image ‘A’.
Visible Watermarking – Concatenation
1. A raw bitmap image ‘A’ will be selected from the set of standard test images. Let this be the base image on which the watermark will be added.
2. A raw bitmap image ‘B’ will be selected from the set of standard test images. This will be the watermark image which will be added to the base image.
3. Now both images ‘A’ and ‘B’ will be concatenated to get a watermarked image ‘D’
