Features Classification Forest: A Novel Development that is Adaptable to Robust Blind Watermarking Techniques [PDF]
A novel watermarking scheme is proposed that could substantially improve current watermarking techniques. This scheme exploits the features of micro images of watermarks to build association rules and embeds the rules into a host image instead of the bit

Techniques in image restoration and enhancement [PDF]
Includes bibliographical references.Image processing in its broad sense pervades many areas but it is convenient to group it into three main sections, viz: image coding, usually for image transmission over telecommunication links; pattern recognition for

A brief summary of digital image enhancement [PDF]
Digital image processing is a modern branch of computer application. With the help of computers the visual quality of original images which were blurred by external interferences or optical transfer function of transmission channel can be improved so ...

Detection of elliptical polarization parameters using a metalens
A metalens capable of detecting the polarization ellipticity of an incident beam is considered in this paper. This metalens consists of blocks with diffraction gratings of a 140-nm height and a 220-nm period.
