1. 1. Accuracy Improvement and Joint Stiction Relieve in Robot Arms Movement Applying Torque-Based Cartesian Impedance Control With Dithering

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Salvador Monzó Martínez; Altin Zejnullahu; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Robots are nowadays present and essential in a wide range of applications, and robot arms in particular are capable of performing various tasks such as inspection, material handling, and welding. They can be classified into several types, depending on their structure and purpose. LÄS MER

3. 2. Real Time Volumetric Ray Marching with Ordered Dithering : Reducing required samples for ray marched volumetric lighting on the GPU

   Magister-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Philip Sköld; [2018]
   Nyckelord :;

   Sammanfattning : Volumetric Lighting is a collective term for visual phenomena that occur due to how light interacts inside so-called participating media, and it accounts for many recognizable effects such as fog or light shafts. Because it isvery computationally expensive, it has been an importantproblem within computer graphics to calculate volumetriclighting, both accurately and efficiently. LÄS MER

4. 3. Compact ConvNets with Ternary Weights and Binary Activations

   Master-uppsats, KTH/Robotik, perception och lärande, RPL

   Författare :Ondrej Holesovsky; [2017]
   Nyckelord :convolutional neural networks; compact architectures; weight quantization; activation quantization; dithering activations;

   Sammanfattning : Compact architectures, ternary weights and binary activations are two methods suitable for making neural networks more efficient. We introduce a) a dithering binary activation which improves accuracy of ternary weight networks with binary activations by randomizing quantization error, and b) a method of implementing ternary weight networks with binary activations using binary operations.

5. 4. Depth Reconstruction Uncertainty Improvement for Skewed Parallel Stereo Pair Cameras Using Dithering Approach

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :ABUBAKR HASSAN BASHIR SIDDIG; [2012]
   Nyckelord :Depth Reconstruction; Dithering; Skewed Parallel; Stereo Setup; Iso-disparity;

   Sammanfattning : Each point in the space is defined by its three dimensions position (x,y,z). However, capturing this point with a camera only translates it to a two dimensional point (x,y). The reconstruction of the missing dimension z is needed to locate the point in the space. LÄS MER

7. 5. Depth Measurement Improvement Using Dithering Method in Sensor-shifted Stereo Cameras

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Wail Mustafa; [2010]
   Nyckelord :Depth Reconstruction; Dithering; Skewed Parallel; Stereo Setup; Iso-disparity surfaces;

   Sammanfattning : The camera stereo system provides the mechanism for obtaining the 3D information of a target point. However, the depth estimation, in particular, suffers from the uncertainty caused by the quantization in the digital images. LÄS MER
