Comparison of visual census and underwater video for fish sampling in Neotropical reservoirs
Environmental Biology of Fishes, 2020Different techniques have been employed for fish surveys in freshwater impoundments, however, despite the increasing applicability of underwater video systems for fish sampling in different aquatic ecosystems, such technology has not been tested in reservoirs.

Visualizing Ambient Population Data within Census Boundaries: A Dasymetric Mapping Procedure
Cartographica, 2008The visualization of areal census data is sensitive to the modifiable areal unit problem. Consequently, though not widely used, dasymetric mapping procedures have been developed to provide a more convincing representation of such areal data. This article extends past research on dasymetric mapping procedures to visualize fine-resolution raster data ...

Popweaver: a program for interpolation and visualization of census and other sparsely collected data
Journal of Population Research, 2017Demographic data is essential to inform socio-economic, epidemiological and other time series analyses. However, demographic data based on interpolations performed on census surveys spaced several years apart often bear severe quality problems, which propagate into studies that make use of those datasets.

Association rules mining and expressing in census data based on geo-visualization
SPIE Proceedings, 2007With the integration of geo-visualization theory and data mining technology, this paper uses geo-visualization assisted association mining method to discover, extract and express the potential spatial distribution relations among census data and other related socio-economic statistical data by using data mining technology.

Indian Census 2011 Data Visualization: A Comprehensive Analysis through Interactive Visual Analytics
SSRN Electronic Journal<p>The livelihood, development, and socioeconomic well-being of human populations across India are significantly shaped by demographic patterns, and these factors are increasingly difficult to interpret due to the massive scale of census datasets. The goal of this project is to create an artificial intelligence (AI)-driven census analytics system

A novel underwater visual census: Seahorse population survey as a case study
Regional Studies in Marine Science, 2016Abstract Two different Underwater Visual Census (UVC1 and UVC2) were performed at three sites in the Ria Formosa, using 30 meter transect belts, and compared for differences in seahorse density and holdfast availability. Each UVC differed in transect placement and total survey area coverage.

Census-based vision for auditory depth images and speech navigation of visually impaired users
IEEE Transactions on Consumer Electronics, 2011In neuroscience and psychology, visual imagery is the subjective experience of seeing in the absence of visual stimulation. Someone may experience touch or sound as a result of visual imagery. In this paper, a new visual image aid which can provide a different way to visualize the image for visually impaired users is proposed.

Littoral fish community in Lampedusa Island: a visual census approach.
1998Fish community structure of the Island Lampedusa, with a special focus on the fish assemblage inhabiting the infralittoral rocky substrate, was studied from July to October 1995. Visual census techniques (strip transects and random censuses) and the application of an anaesthetic (quinaldine), to sample cryptic and benthic species, were used. A total of
