Cloud detection and analysis from satellite images has been a topic of research in many atmospheric and environmental studies; however, it still is a challenging task for many reasons. In this paper, we propose a new method for cloud-type classification using fuzzy logic. Knowing that visible-light images of clouds contain thickness related information, while infrared images haves height-relate...

We explore how context change and item variation during natural category learning influence memory and generalization to new examples. Participants studied either images of the same bird or varied birds from each of several categories. These images could be presented in a constant background color or different background colors. During test, birds were presented in only one of the studied backg...

3⁄4 Digital cameras capable of 24-bit color (16.8 million colors) provide a unique and relatively inexpensive tool for teaching the physics of light. Many students are familiar with colors obtained by mixing different colors of paint. These color combinations represent subtractive color. Projected light, such as that emanating from the sun and reflected by objects, combines to form different ad...

Learning color words is a difficult problem for young children. Because color is abstract, this difficulty has been attributed to challenges in integrating over heterogeneous objects to discover color as a dimension of reference. On this account, learning that color words refer to the color dimension is slow, but subsequently mapping these words to particular shades is fast. Recent work suggest...
