In this paper we estimate the minimum prevalence of grapheme-color synesthetes with letter-color matches learned from an external stimulus, by analyzing a large sample of English-speaking grapheme-color synesthetes. We find that at least 6% (400/6588 participants) of the total sample learned many of their matches from a widely available colored letter toy. Among those born in the decade after t...

One of the most fundamental features of scientific visualization is the process of mapping scalar values to colors. This process allows us to view scalar fields by coloring surfaces and volumes. Unfortunately, the majority of scientific visualization tools still use a color map that is famous for its ineffectiveness: the rainbow color map. This color map, which näıvely sweeps through the most s...

Compound document images are usually high resolution and high quality images that include color, graphics, and images in addition to text. The need for good compression is important for storage and transmission. Due to the large size, even compressed, it is often difficult to access document images quickly and efficiently for display on monitors. The nascent JPM file format enables the best com...

Stand boundary identification is an important factor in forest management planning that is dependent on the quality and resolution of the imagery available. We identified stand boundaries on an area within the John C. Stennis Space Center using two sources of multispectral imagery, IKONOS and QuickBird. Forest stands were delineated using eCognition v3.0. Segmentation was performed by initially...

Realistic rendering of outdoor terrain requires both that the geometry of the environment be modeled accurately and that appropriate texturing by laid down on top of that geometry. While elevation data is widely available for much of the world and many methods exist for converting this data to forms suitable for graphics systems, we have much less experience with patterning the resulting surfac...

Several ocean color earth observation satellite sensors are presently collecting daily imagery, including the Hyperspectral Imager for the Coastal Ocean (HICO). HICO has been operating aboard the International Space Station since its installation on September 24, 2009. It provides high spatial resolution hyperspectral imagery optimized for the coastal ocean. Atmospheric correction, however, sti...
