A computer-implemented method for optimizing a design of a physical object comprises: obtaining a data representation of the design of the physical object, including a plurality of elements, determining plural element clusters comprising a plurality of elements and estimating a cost model for the physical object. The method determines derivatives of the cost model with respect to a material density of each cluster. At least one analytical derivative of a performance metric for each element is computed. The design is optimized by iteratively performing: varying the material density of at least one element based on the analytical derivative and the estimated derivatives of the cost model, estimating the cost using the cost model based on the data representation with varied material density. The method generates and outputs a signal comprising the optimized data representation in case a termination criterion has been met.

Method for structural optimization of a design and cost of a physical object

A system and method for automatically generating an appealing visual based on an original visual captured by a vehicle mounted camera are provided. A semantic image content and its arrangement in the original visual is computed; an optimization process is performed that improves an appeal of the original visual by making it more similar to a set of predetermined traits. The optimization process may include adding information to the original visual to generate an enhanced visual by adapting content from further visuals, and adapting iteratively a geometric parameter set of the enhanced visual to generate a certain perspective or morphing to improve an arrangement of semantics in the enhanced visual. The optimized parameter set may be applied to the enhanced visual. Post-processing may be conducted after applying the optimized parameter set using a set of templates to generate a final visual that may be output for immediate or later use.

The invention regards a method for reproducing visual and/or audio data synchronously by a group of devices, as well as a system for realizing such method. According to the invention first, a spatial location of each of the devices of the group is determined. Then, the visual and/or audio content is partitioned into content parts, each part dedicated to be reproduced by one device of the group respectively, based on the spatial location of the device. The dedicated portions are transmitted to their associated devices together with a time stamp, and the group of devices reproduces commonly and synchronously the transmitted portions.

An improved method for optimizing a design, based on direct manipulations of the object points of a design. In addition, the number and modifications of control points is kept as minimal as possible while the targeted movement of object points is realized and the automatic adaptation and generation of a set of control points for deformations which allows the movement of object points to desired positions. One aspect of the invention is to generate the transformation function f which is optimized to be able to realize desired changes of object parameters by means of control point variations. This optimization can be realized in a way that the mapping between the original coordinate system of the design and the spline coordinate system is not changed, so that no additional 'freezing' process (the generation of the mapping between the coordinate systems) is necessary.

Evolutionary direct manipulation of free form deformation representations for design optimization

A method for modifying an object design using a computer comprises the steps of: selecting a first sub-design of the object design comprising a first free form deformation geometry and a first free deformation control volume that is variable and adaptive; choosing a second sub-design comprising a second free form deformation geometry; and replacing the first geometry with the second geometry.

An improved optimization of a design, based on direct manipulations of the object points of a design where the number and modifications of control points is kept as minimal as possible while the targeted movement of object points is realized.

Evolutionary design optimization using extended direct manipulation of free form deformations

Techniques are provided for representation of designs using a basic design which is then modified by a transformation function. In free form deformation techniques the transformation function is defined by a spline function which transforms the space in which the design is defined into a second space where the new modified design is defined. During the design process the parameters of the spline function determine the parameters of the transformation function. While using Evolution Strategies, parameters of the spline function also determine the parameters the optimization algorithm works in. In order to adapt the transformation function optimally to the given problem and the necessary modification a mutation operator is proposed which allows introduction and deletion of control points. Instead of the standard mutation operator in evolution strategies this mutation operator works on the representation of the problem/design.
