  2. 1. 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

  4. 2. Reinforcement Learning for Active Visual Perception

    Author : Aleksis Pirinen; Mathematical Imaging Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; reinforcement learning; deep learning; active vision; object detection; human pose estimation; semantic segmentation;

    Abstract : Visual perception refers to automatically recognizing, detecting, or otherwise sensing the content of an image, video or scene. The most common contemporary approach to tackle a visual perception task is by training a deep neural network on a pre-existing dataset which provides examples of task success and failure, respectively.

  5. 3. Active and Physics-Based Human Pose Reconstruction

    Author : Erik Gärtner; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; human pose estimation; reinforcement learning; physics-based human pose estimation; active learning;

    Abstract : Perceiving humans is an important and complex problem within computervision. Its significance is derived from its numerous applications, suchas human-robot interaction, virtual reality, markerless motion capture,and human tracking for autonomous driving. The difficulty lies in thevariability in human appearance, physique, and plausible body poses. READ MORE

  6. 4. Natural Vision for Artificial Systems, Active Vision and Thought

    Author : Lars Kopp; Kognitiv semiotik; []
    Keywords : HUMANIORA; HUMANITIES; visual alphabet; representations; robotics; language; artificial vision; cognition; Artificial intelligens; Artificiell intelligens;

    Abstract : The visual system in animals and humans consists of a number of information processing units that are here called visual routines. These routines are specialized in handling different cognitive tasks, for example, object recognition, motion, stereo, color, texture, and optic flow. READ MORE

  7. 5. Neurons against Noise : Neural adaptations for dim light vision in hawkmoths

    Author : Anna Stöckl; Funktionell zoologi; []
    Keywords : vision; insect; hawkmoth; motion vision; spatial and temporal summation; dim light; neural processing;

    Abstract : All animals perceive the world through their senses, which form the basis for their decisions and motor actions. However, when these all-important senses reach their limit and cease to provide reliable information, the animal’s survival is threatened. READ MORE
