Bringing the Advantages of 3D Distortion Viewing into Focus

Some recent developments in the area of multi-scale viewing have concerned the creation of such views from magnification factors as input. We present an algorithm in which magnification factors are used directly to control the creation of a multiscale view in a 3D based distortion viewing. Our algorithm relies on the basic geometry of a perspective view volume, the properties of which provide a...

3D Power Packaging with Focus on Embedded Substrate Technologies

The power electronics industry and the semiconductor industry, inseparably intertwined with one another, are facing unprecedented efficiency, cost, construction and thermal challenges which provide many opportunities for innovation. These industries are in the focal point of the “energy challenge” a multifaceted problem that involves mobile and cloud infrastructure systems, Internetof-Things, r...

3D Image Acquisition System Based on Shape from Focus Technique

This paper describes the design of a 3D image acquisition system dedicated to natural complex scenes composed of randomly distributed objects with spatial discontinuities. In agronomic sciences, the 3D acquisition of natural scene is difficult due to the complex nature of the scenes. Our system is based on the Shape from Focus technique initially used in the microscopic domain. We propose to ad...

Can 3D Shape be Estimated from Focus Cues Alone?

0.6 D Four subjects were asked to judge the shape of a hinge (convex or concave). Rendered blur and optimized stimuli were generated using a simulated aperture equal to the subject’s measured pupil size under experimental conditions. Hinges were presented monocularly (removing disparity cue) and textured in screen space (removing texture cue). Stimulus duration: 0.3 s, 3 s, or 5 s Vertex distan...
