1. 11. The Förstner Interest Point Operator Subwindow Localization on SIFT Keypoints

   University essay from Umeå universitet/Institutionen för fysik

   Author : Viktor Jakobsson; [2015]
   Keywords : Photogrammetry; Subwindow; Localization; SIFT;

   Abstract : This thesis suggests a modification to the popular Scale Invariant Feature Transform (SIFT) algorithm (Lowe, 2004) often used in photogrammetry and computer vision to find features in images for measurement. The SIFT algorithm works by first detecting points in images at different scales and sizes. READ MORE

3. 12. Stabilizing Projected Points inAugmented Reality Applications

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : ANDERS JÄRLEBERG; [2014]
   Keywords : ;

   Abstract : Positioning projected points in a mobile Augmented Reality application based only on the orientation sensor of the device can cause instability due to variations in the sensor data. A method is proposed to use the image data from the camera feed of the device in order to stabilize the points. READ MORE

4. 13. Calibration of Laser Triangulating Cameras in Small Fields of View

   University essay from Datorseende; Tekniska högskolan

   Author : Daniel Rydström; [2013]
   Keywords : Homography; calibration; 3D; laser plane; triangulation; camera; lens distortion; non-linear optimisation;

   Abstract : A laser triangulating camera system projects a laser line onto an object to create height curveson the object surface. By moving the object, height curves from different parts of the objectcan be observed and combined to produce a three dimensional representation of the object. READ MORE

5. 14. Autonomous Morphometrics using Depth Cameras for Object Classification and Identification

   University essay from Datorseende; Tekniska högskolan

   Author : Felix Björkeson; [2013]
   Keywords : Depth Cameras; Classification; Morhometrics; Homography; B-Spline; Eigenfaces; Fisherfaces; Local Binary Pattern Histograms; Nerual Network;

   Abstract : Identification of individuals has been solved with many different solutions around the world, either using biometric data or external means of verification such as id cards or RFID tags. The advantage of using biometric measurements is that they are directly tied to the individual and are usually unalterable. READ MORE

6. 15. Real-time Embedded Panoramic Imaging for Spherical Camera System

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Main Uddin-Al-Hasan; [2013]
   Keywords : Panorama Image; Image stitching; Image registration; SURF; Real-time computing; Gumstix Overo COM; PandaBoard ES; Embedded Linux; RTLinux; Real-time kernel; Embedded development; OpenCV; FFMPEG; V4L2; Computer Vision; QT framework;

   Abstract : Panoramas or stitched images are used in topographical mapping, panoramic 3D reconstruction, deep space exploration image processing, medical image processing, multimedia broadcasting, system automation, photography and other numerous fields. Generating real-time panoramic images in small embedded computer is of particular importance being lighter, smaller and mobile imaging system. READ MORE
