Light shaping techniques based on phase-only modulation o er multiple advantages over amplitude modulation. This review examines and compares the merits of two phase modulation techniques; phase-only computer generated holography and Generalized Phase Contrast (GPC). Both techniques are brie y presented while recent developments in GPC will also be covered. Furthermore, novel hybrid schemes tha...

Since its conception, holography has been put to a variety of uses including data storage, security, and interferometry. However, perhaps the most popular application of holography is using the technique to make three-dimensional images [1]. This paper describes an algorithm for computationally generating holograms along with methods to fabricate the hologram. Holography has since made a jump f...

A method that combines the high speed of digital encryption and the high security of optical encryption with the advantages of electronic transmission, storage, and decryption is introduced. The encryption is performed by use of multi-dimensional lock on the hologram plan, providing high security in the encrypted image and a key with many degrees of freedom. We described how our method can be a...

In this work, a concept for the execution and kinematic analysis of motion studies is introduced and realized, adding innovative computer-aided methods to the so far existing procedures. Firstly, a classification assistant for grouping kinematic motion data is developed and evaluated, which is alternatively based on Adaptive Resonance Theory or Self-Organizing Feature Maps. It can be demonstrat...

Morphons and Bions is a real-time, computer-generated work that uses white noise as the fundamental synthesis component combined with classical synthesis techniques. Random and stochastic processes control the synthesis parameters. This approach creates sounds evocative of living mechanisms. The sonic mechanisms can metamorphose between noisy, engine-like sounds to pitched, chatter-like sounds....

NPR Lenses is an interactive technique for producing expressive non-photorealistic renderings. It provides an intuitive visual interaction tool for illustrators, allowing them to seamlessly apply a large variety of emphasis techniques. Advantages of 3D scene manipulation are combined with the capabilities of viewer-aligned lenses by inserting 2D lens controls into the 3D rendering pipeline. By ...

We present computer-generated proofs of some summation identities for (q-)Stirling and (q-)Eulerian numbers that were obtained by combining a recent summation algorithm for Stirling number identities with a recurrence solver for difference fields.

The increasing number of experimenters using computer-generated experimental designs creates an increasing need to have design procedures that are less sensitive to model misspecification. To address this problem, the notion of empirical models that have both important and potential terms is used. A two-stage design strategy for planning experiments in the face of model uncertainty is proposed....

This paper presents an efficient compression-oriented segmentation algorithm for computer-generated document images. In this algorithm, a document image is represented in a block-based multiscale pyramid. Then, image blocks will be characterized based on their entropy values of the intensity histogram, and the entropy distribution are assumed to be Gaussian priors in this work. We will discuss ...

This paper describes how statistical methods can be tested on computer-generated data from known models. We explore bias and percentile tests in detail, illustrating these with examples based on insurance claims and financial time series.
