Poštovane članice i članovi Hrvatske sekcije IEEE,

 

Pozivamo Vas na predavanje u organizaciji projekta ACROSS, Odjela za obradu signala i Odjela za električne krugove i sustave Hrvatske sekcije IEEE koje će se održati u petak 13. 6. 2014. u 14:15 sati u knjižnici ZESOI.

 

Predavač je:

Dr. Robert Bregović

 

Naslov predavanja je:

Light field: From concept to display

 

Sažetak predavanja:

The ultimate goal of visualization technologies is to visualize on a display (device) a ‘perfect’ representation of a 3D scene. This goal will be achieved when a scene visualized on a display is indistinguishable from the real one. Although, today’s display technology is still not able to reproduce such level of realism (visual quality), the requirements for achieving this are quite well understood. In this talk we will discuss the concept of light field as the underlying principle for a complete description of a 3D scene. We will show its formal definition through the plenoptic function and introduce several light field representations with the corresponding interpretation in spatial and frequency domain. Scene representations ranging from pure image-based, such as Epipolar-Plane Image (EPI) based, to multi-view multi-depth based will be considered. We will also look into available light-field displays that are trying to generate the required light field defined by a scene. We will end the talk by pointing out advantages and disadvantages of those displays over more widely available off-shelf 3D displays (e.g. autostereoscopic and glasses-based 3D displays).

Visual-quality evaluation methodology for multiview displays

 

Sažetak predavanja:

Multiview displays are characterized by a multitude of parameters, such as spatial resolution, brightness, 3D-crosstalk, and so forth, which individually and in combination influence the visual quality of 3D scenes. These parameters are specified by values precisely measured by optical means. However, it is difficult for an average consumer or content producer to compare the visual quality of two displays or to judge whether given 3D content is suitable for a certain display using only this set of parameter values. In this talk, we will describe a quality-measurement methodology that aims to measure the visibility of structural distortions introduced by a multiview display by using a number of test signals with different frequency content and apparent depth. We use these measurements to derive what we call display passband for signals at different disparity levels. The passband determines the frequency components for which the intended signal is predominantly visible with respect to the distortion introduced by the display. Additionally, we look into a method to determine the approximate effective resolution of a display for signals with a given apparent depth. The result of the measurements can be used to compare the perceived visual quality of different multiview displays.

Naslov predavanja je:

Multi-sensor 3D visual scene capture

 

Sažetak predavanja:

We propose a joint de-noising and data fusion approach where the fused modalities come from conventional high-resolution photo or video camera and low-resolution range sensor of time-of-flight type, operating in restricted conditions of low-emitting power and low number of sensor elements. Our approach includes identifying the various noise sources and suggesting suitable remedies at particular stages of data sensing and fusion. More specifically, fixed pattern noise and system noise are treated at a preliminary denoising stage working on range data only. In contrast to other 2D video/depth fusion approaches, which suggest working in planar coordinates, our approach includes additional denoising refinement in the space of 3D world coordinate system (i.e. point cloud space). Furthermore, the high-resolution grid resampling is performed as an iterative non-uniform to uniform resampling based on the Richardson method. This improves the performance compared to approaches based on low-to-high grid upsampling and subsequent refinement. We report experimental results where the achieved quality of fused data is the same as if the ToF sensor was operating in normal (low-noise) sensing mode.

Inductorless Elliptic Filters with Reduced Number of Capacitors Using Signal-Flow Graphs

Sažetak predavanja:
A method of realizing elliptic filters using signal-flow graphs is presented. Elliptic filters having a minimum number of capacitors are compared with those having a higher number of capacitors. This number is particularly significant when comparing filters realized in balanced-to-ground and unbalanced form. The version with a canonic number of capacitors provides area savings in IC form, whereas both (filters with a minimum [i.e. canonic] number of capacitors and those having a higher number of capacitors) have a low sensitivity to component tolerances. The sfg derivations necessary to realize higher-order elliptic filters with a reduced number of capacitors is presented. Transfer function magnitudes are simulated using the PSpice program. Monte Carlo runs confirm the low sensitivity to component tolerances of both circuit types.
