Mapping Visual Perceptions using Google Street View

  1. 1. Perceptual Maps: Mapping the visual perception oftravelers in a city using google street view as sensor Keywords: Psychogeography, computer vision, Art, Flaneur/Baudelaire Each geotagged panoramic image = visual sensor of the area What if I use every google street images of a city (e.g. Paris) and analyze specific visual perception/feature to create perceptual maps?
  2. 2. Example: Claustrophobia Map - sensing the“openness” of urban spaces.Question: Where are the most open spaces in Paris?  how much sky can I perceive if I travel there? People perception angle when traveling
  3. 3. Mapping the perceptionEach colored point on the maprepresents the degree of “openness” ofan area (computed for each associatedgoogle street view image) Dark area = Average openness= Orange/Red point (yellow point)

  6. 6. Level of green perception inthe network of Paris(Perceptual GPS: I want a “green” travel,guide me using such a map!)
  7. 7. unachieved personal research projectTODO• Exploring other visual features (e.g. mapping the “colourfulness” of an area), detecting specific textures (e.g. mapping architectural styles in a city)• Perceptual GPS: programming travels in a city according to visual perceptions (see also “random GPS” /“serendipity in a physical network” project)---- What is the goal of such kind of maps?”- just the pleasure to explore new maps: mapping the visual perception of travelers in a city. (not enough time to explore fully the concept)Contact: n.maisonneuve@gmail.com (nicolas maisonneuve)
