The JPEG image compression scheme is the standard method for compressing true color images. Since most computer systems have a clut-oriented graphic device, a color quantization process is required for displaying true color images on such systems. Unfortunately, the general color quantization problem is NP-hard and is therefore solved by suboptimal heuristic approaches with reduced visual quali...

Rodent monitoring in biomedical laboratories is a time consuming and tedious task. Several automatic solutions that rely on different types of sensors have been proposed. Computer vision provides a significantly more universal and less intrusive solution. In this article we propose a new method to detect and classify three behaviors in rodents: Exploring, Rearing, and Static. The method uses Mo...

A new formalism to generate pseudocolor spectra is introduced. Therefore, a para-metric path in the RGB{color cube is derived to guarantee constant brightness progression. The resulting spiral{like curve allows the generation of various color spectra by adjusting the spiral's frequency and phase. The formalism allows the determination of the resulting number of colors in dependency of both para...
