Vectorisation of Sketches with Shadows and Shading using COSFIRE filters [PDF]
Proceedings of the ACM Symposium on Document Engineering 2018, 2018 Engineering design makes use of freehand sketches to communicate ideas, allowing designers to externalise form concepts quickly and naturally. Such sketches serve as working documents which demonstrate the evolution of the design process. For the product design to progress, however, these sketches are often redrawn using computer-aided design tools to ...

Low-Cost PVD Shadow Masks with Submillimeter Resolution from Laser-Cut Paper
Micromachines, 2020 We characterize an affordable method of producing stencils for submillimeter physical vapor deposition (PVD) by using paper and a benchtop laser cutter. Patterning electrodes or similar features on top of organic or biological substrates is generally not

Axis-aligned filtering for interactive sampled soft shadows [PDF]
ACM Transactions on Graphics, 2012 We develop a simple and efficient method for soft shadows from planar area light sources, based on explicit occlusion calculation by raytracing, followed by adaptive image-space filtering. Since the method is based on Monte Carlo sampling, it is accurate.

Sub-shot-noise shadow sensing with quantum correlations [PDF]
, 2017 The quantised nature of the electromagnetic field sets the classical limit to the sensitivity of position measurements. However, techniques based on the properties of quantum states can be exploited to accurately measure the relative displacement of a ...

Shadow Information Spaces: Combinatorial Filters for Tracking Targets [PDF]
IEEE Transactions on Robotics, 2012 This paper introduces and solves a problem of maintaining the distribution of hidden targets that move outside the field of view while a sensor sweep is being performed, resulting in a generalization of the sensing aspect of visibility-based pursuit-evasion games. Our solution first applies information space concepts to significantly reduce the general
