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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Reinforcement Learning for Active Visual Perception

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

    Sammanfattning : 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.

  3. 3. Natural Vision for Artificial Systems, Active Vision and Thought

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Ommatidial adaptations for vision in nocturnal insects

    Författare :Rikard Frederiksen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gain of transduction; Information rate; Signal-to-noise ratio; Apposition eye; Optical sensitivity; Nocturnal insects; Superposition eye; Vision;

    Sammanfattning : Nocturnal vision is a demanding task for insects with small eyes. As it gets dimmer the noise imposed by the stochastic nature of photon arrival makes vision unreliable. Despite this, there are quite a number of animal species that are active at night and apparently see well. LÄS MER
