Medical image watermarking represents a promising alternative tool regarding many security aspects such: digital rights, authenticity and integrity content protection issues. Achieving successful should be achieved by choosing the most significant important patterns describing image. This strategy also ensure tradeoff between robustness of watermark against attacks computational time both for e...

Optical Character Recognition (OCR) is a method for computer to process an image that contains some text and then try find any characters in image, convert it digital text. In this research, Advanced Local Binary Pattern Chain Code algorithm will be tested identify alphabets the image. Several preprocessing are also needed, such as transformation, rescaling, grayscale conversion, edge detection...
