Abstract: An image editing application (or a blur classification module thereof) may automatically estimate a coherent defocus blur map from a single input image. The application may represent the blur spectrum as a differentiable function of radius r, and the optimal radius may be estimated by optimizing the likelihood function through a gradient descent algorithm. The application may generate the spectrum function over r through polynomial-based fitting. After fitting, the application may generate look-up tables to store values for the spectrum and for its first and second order derivatives, respectively. The use of these tables in the likelihood optimization process may significantly reduce the computational costs of a given blur estimation exercise. The application may minimize an energy function that includes a data term, a smoothness term, and a smoothness parameter that is adaptive to local image content. The output blur map may be used for image object depth estimation.

Abstract: A switched-capacitor ripple-smoothing filter includes a first pair of capacitors. The filter is configured such that either capacitor in the first pair may be reset and have a terminal coupled to a first input port and such that the remaining capacitor in the first pair is isolated from the first input port and has the terminal coupled to a first output port while the other capacitor is being charged. The filter further includes a second pair of capacitors, the filter being configured such that either capacitor in the second pair may be reset and have a terminal coupled to a second input port and such that the remaining capacitor in the second pair is isolated from the second input port and has the terminal coupled to a second output port while the other capacitor in the second pair is being charged. Advantageously, the filter is configured such that the capacitors in the first and second pair are reset responsive to the assertion of a single reset signal.

Abstract: A circuit topology for high-speed printed circuit board includes a driving circuit, and a number of receiving circuits. The driving circuit is mounted on the printed circuit board and coupled to a node via a transmission line. The receiving circuits receive signals transmitted from the driving circuit. Each receiving circuit is coupled to the node separately via a transmission line. Transmission line lengths between each of the receiving circuits and the node are substantially equal. The close the node is to the receiving circuits, the better the signal integrity. Using the circuit topology maintains signal integrity as the termination resistor does. It is of advantage that the circuit topology is simple to manufacture and very suitable for mass production.

Abstract: A head for directing radiated energy from a source to a coordinate in a field of view defined by at least one of azimuth and elevation, comprises an angled element and a planar reflecting element. The angled element rotates about a first axis and redirects the beam, the redirection of the angled element differing in at least one of direction and extent as it is rotated. An axis normal to the surface extends at an angle to the second axis. The reflecting surface receives the redirected beam at a point thereon and reflects it in a direction within the FOV. A rotator may be positioned between the source and the angled element to support and independently rotate the angled element and the reflecting surface about the first and second axes without impeding the energy.
