2. 1. Spatio-Temporal Scale-Space Theory

   Author : Daniel Fagerström; Jan-Olof Eklundh; Luc Florack; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Bildanalys;

   Abstract : This thesis addresses two important topics in developing a systematic space-time geometric approach to real-time, low-level motion vision. The first one concerns measuring of image flow, while the second one focuses on how to find low level features. READ MORE

4. 2. On the evaluation of print mottle

   Author : Carl-Magnus Fahlcrantz; Jan-Olof Eklundh; Jon Hardeberg; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mottle; Print quality; Texture; Image analysis; Perception; Computer science; Datalogi;

   Abstract : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. READ MORE

   Abstract : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. READ MORE

6. 4. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects

   Author : Babak Rasolzadeh; Jan-Olof Eklundh; Ales Leonardis; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

   Abstract : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. READ MORE

7. 5. The Texture-Transform : An Operator for Texture Detection and Discrimination

   Author : Alireza Tavakoli Targhi; Jan-Olof Eklundh; Arnold Smeulders; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

   Abstract : In this thesis we present contributions related to texture detection and discrimination to be used for analyzing real world images. Many computer vision applications can benefit from a fast and low dimensional texture descriptor. READ MORE
