摘要： The invention concerns a gesture recognition method for gesture-based interaction at an apparatus. The method comprises receiving one or more images of an object; creating feature images for the received one or more images; determining binary values for pixels in corresponding locations of said feature images and concatenating the binary values to form a binary string for said pixel; repeating the previous step for each corresponding pixel of said feature image to form a feature map and forming a histogram representation of the feature map. The invention also concerns an apparatus and a computer program.

摘要： The present invention relates to a method of selecting a subset of patterns from a design, to a method of performing source and mask optimization, and to a computer program product for performing the method of selecting a subset of patterns from a design. According to certain aspects, the present invention enables coverage of the full design while lowering the computation cost by intelligently selecting a subset of patterns from a design in which the design or a modification of the design is configured to be imaged onto a substrate via a lithographic process. The method of selecting the subset of patterns from a design includes identifying a set of patterns from the design related to the predefined representation of the design. By selecting the subset of patterns according to the method, the selected subset of patterns constitutes a similar predefined representation of the design as the set of patterns.

摘要： One embodiment of a method for process window optimized optical proximity correction includes applying optical proximity corrections to a design layout, simulating a lithography process using the post-OPC layout and models of the lithography process at a plurality of process conditions to produce a plurality of simulated resist images. A weighted average error in the critical dimension or other contour metric for each edge segment of each feature in the design layout is determined, wherein the weighted average error is an offset between the contour metric at each process condition and the contour metric at nominal condition averaged over the plurality of process conditions. A retarget value for the contour metric for each edge segment is determined using the weighted average error and applied to the design layout prior to applying further optical proximity corrections.

An apparatus for detecting validation of an ACL is also disclosed in the present invention. The apparatus can implement neither increasing the network load nor impacting the safety of a Central Processing Unit (CPU) in a device while judging whether an ACL rule takes effect or not.
