The capacity of embedding = (the number of bytes of watermarked data/number of bytes of the host image)x100% from the host image; the watermarked images after embedding within all blocks of selected host images.

Not Foolproof Using the clone or trimming tools, even a novice can remove your watermark in one of these editing programs. An unscrupulous thief may even place his own watermark on the image after removing yours. Watermarks do not offer foolproof protection against theft.

The process of watermark embedding is using a watermarking key and the watermarking algorithm, to produce the watermarked digital image. The embedding method vary based on which image domain is being processed, e.g. the space, frequency domain or the wavelets.

Watermarking capacity refers to the amount of information we are able to insert into the image. Low signal to noise ratio SNR is a phenomenon of watermarking channels which severely limits the capacity. For watermarking image, high embedding capacity may be needed (Zaidan et al., 2010).

You must strike a balance with being transparent enough to not detract from the picture but also opaque enough to be read and deter thieves. What is the best size for a watermark? Some photographers will say that your watermark shouldn't be over 1/16 of the photo.

If it's too small, you lose clarity and quality and have to scale it up. A resized image between 500 and 1000 pixels on the wide side works for most watermarks. Drag and drop your logo into your new document or select the text tool to add text. You can use any color.
