Anchor images and information associated therewith are accumulated during a Web crawling operation. One or more rules are applied to the accumulated candidate anchor images to filter out candidate anchor images that are not appropriate for use as the anchor image for a particular target video. The remaining candidate anchor image is then selected as the anchor image for the particular video.

An omnidirectional-view three-dimensional display apparatus comprises a high-frame-rate projector (21), a rotatable reflector device and a cylindrical transmissive selective-diffusing screen (24). The optical axis of the high-frame-rate projector (21) is coincident with the rotating axis of the reflector device and the axis of the cylindrical selective-diffusing screen (24). The images projected by the high-frame-rate projector (21) are reflected by the reflector device to form images on the cylindrical transmissive selective-diffusing screen (24). The cylindrical transmissive selective-diffusing screen (24) can control the diffusing angle of the emergence ray, so that the left eye and the right eye of an observer can see a three-dimensional object's images in different view angles to achieve an omnidirectional-view three-dimensional display. The omnidirectional-view three-dimensional display apparatus based on the high-frame-rate projector (21) enables the eyes of observers to watch images with binocular parallax at different positions, so as to achieve three-dimensional display.

Methods and apparatus are provided for manipulating content displayed on a touch screen utilizing a transparent pressure-sensing touch panel. A method comprises displaying content on the touch screen and obtaining one or more pressure metrics for an input gesture on the transparent pressure-sensing touch panel. Each pressure metric corresponds to pressure (or force) applied to the transparent pressure-sensing touch panel by a respective impression of the input gesture. The method further comprises adjusting the displayed content on the touch screen in response to the input gesture, wherein the displayed content is adjusted based on to the one or more pressure metrics for the input gesture.

Systems and methods are provided for authenticating an input on a touch screen. A method comprises obtaining one or more pressure metrics for an input by a user on a touch screen that is being proffered as that of a known user. Each pressure metric corresponds to a pressure applied to the touch screen by the user at a respective impression location of the input. The method further comprises authenticating the user as the known user based at least in part on the one or more pressure metrics.

Disclosed is a method for controlling the shapes of FM-AM mixed halftone dots on the multi-bit depth imaging apparatus. In the prior art, since the reproduction of the shapes of the dots in various gradations is absolutely based on the theory of random error diffusion and is influenced by the dynamic controlling output mechanism for the multi-bit dots, it is hard to assure the controllability of the shapes of the dots in a certain gradation. Based on the prior art, the dynamic statistic algorithm with adjacent output gray levels is introduced to assure the controllability of the shapes of the dots and solve the problem of random change of the shapes of the dots due to the randomicity of the error diffusion. According to the disclosed method, the features of the multi-bit imaging apparatus can be achieved fully in light of the requirements of the dots on the basis of the original method for multi-bit FM-AM mixed screening using error diffusion based on dual-feedback. The effect of FM-AM mixed halftone screening can be achieved under low resolution with controllable shapes of the dots, The problem of granular sensation can be solved during the practical output of the mixed halftone dots so as to assure the smooth effect of the gradations.
