Abstract: Techniques are disclosed herein for implementing a novel, low latency, guidance map-free video matting system, e.g., for use in extended reality (XR) platforms. The techniques may be designed to work with low resolution auxiliary inputs (e.g., binary segmentation masks) and to generate alpha mattes (e.g., alpha mattes configured to segment out any object(s) of interest, such as human hands, from a captured image) in near real-time and in a computationally efficient manner. Further, in a domain-specific setting, the system can function on a captured image stream alone, i.e., it would not require any auxiliary inputs, thereby reducing computational costs—without compromising on visual quality and user comfort. Once an alpha matte has been generated, various alpha-aware graphical processing operations may be performed on the captured images according to the generated alpha mattes (e.g.

Abstract: A system and method for providing advertising server optimization for online computer users is disclosed. A particular embodiment includes obtaining an advertisement; defining a set of features of the advertisement; generating a predicted click through rate (CTR) corresponding to the advertisement based in part on the set of features; ranking the advertisement based on the generated click through rate; and serving the advertisement based on the ranking.

Abstract: A computer-implemented method and system for keyword bidding are disclosed. A particular embodiment includes identifying a keyword searched by a buyer on a host site just prior to their purchase transaction; recording a host site category associated with the purchase transaction; correlating the keyword with the host site category; determining a revenue per click value associated with the keyword; obtaining bidding information associated with the keyword; and automatically generating a bid value for the keyword based on the revenue per click value, the bidding information, and the host site category.

Abstract: A peptide-chelate with affinity for the ST receptor is disclosed, wherein the chelate is tetradentate. The peptide-chelate conjugate of the invention may be labelled with a radiometal to provide a metal complex. A radiopharmaccutical composition comprising the metal complex is provided, which is suitable for the diagnostic imaging of colorectal cancer. Also provided for in the invention is a kit for the preparation of the radiopharmaceutical preparation.

Abstract: The invention relates to MR contrast media containing composite nanoparticles, preferably comprising a superparamagnetic iron oxide core provided with a coating comprising an oxidatively cleaved starch coating optionally together with a functionalized polyalkyleneoxide which serves to prolong blood residence.
