Designers must create different alternatives for web-content and design different layouts for different devices. Traditional image resizing techniques are oblivious to the content of the image when changing its height or width. In contrast, media (i.e., image and video) retargeting takes content into account. For example, one would like to change the aspect ratio of a video without making human figures look too fat or too skinny, or change the size of an image by automatically removing “unnecessary” portions while keeping the “important” features intact. Here is a simple operator; seam carving to support image and video retargeting. A seam is an optimal 1D path of pixels in an image, or a 2D manifold in a video cube, going from top to bottom, or left to right. Optimality is defined by minimizing an energy function that assigns costs to pixels. Here showing that computing a seam reduces to a dynamic programming problem for images and a graph min-cut search for video and also demonstrate that several image and video operations, such as aspect ratio correction, size change, and object removal, can be recast as a successive operation of the seam carving operator.

The implementation of the QCA technology has been demonstrated with metal-dot QCA devices at very low (e.g., cryogenic) temperatures. Circuit structures such as the majority gate, binary wires and fan outs have been fabricated with metal-QCA dots. A quantum-dot cellular automata (QCA) design of an nxm-bit, shift-register-based memory architecture is presented. The architecture maintains data at a stable conformation, which is contrary to traditional data in-motion concept for QCA architectures. The memory architecture is based on an existing dual-phase-synchronized, line-based, one-bit QCA memory cell building block that provides size and latency improvements over other known one-bit memory cells through its novel clocking scheme. Read/write latencies up to ~2X lower than the existing tile-based architecture with three-phase, line-based memory cells are obtained.
