A Novel Approach to Real-time Bilinear Interpolation [PDF]
Second IEEE International Workshop on Electronic Design, Test and Applications, 2005 Bilinear interpolation is often used to improve image quality after performing spatial transformation operations such as digital zooming or rotation. In the traditional case where the input coordinates appear in a raster-based fashion, the required pixel values can be obtained from the previous calculation, the frame buffer and a single line cache ...

Ecography, EarlyView.Patterns in functional and phylogenetic diversity reflect ecological and evolutionary relationships among taxa, and thus can offer key insights into the mechanisms underlying species distributions. However, disentangling the relative influence of proximate environmental drivers versus biogeographic evolutionary history can be a challenge.

Numerical function generators using bilinear interpolation
2008 International Conference on Field Programmable Logic and Applications, 2008 Two-variable numerical functions are widely used in various applications, such as computer graphics and digital signal processing. Fast and compact hardware implementations are required. This paper introduces the bilinear interpolation method to produce fast and compact numerical function generators (NFGs) for two-variable functions.

Ecography, EarlyView.In shelf ecosystems, benthic invertebrates facilitate nutrient recycling and the transfer of energy to higher trophic levels. However, large‐scale monitoring through direct sampling (e.g. using benthic grabs or bottom trawls) can be costly in terms of time and labor.
