Resumen:
This paper presents a program’s description for detecting a specific color in a video sequence. This program was developed using the software Matlab 7.7 which allows us to manage video from a Webcams or an AVI format file in the memory. The goal of the program is to follow an object with an specific color with the option of plotting its trajectory and obtaining its center position (x,y). The color pursuit can be applied in the analysis of cellular organisms which have specific color from their nature. The pursuit of a cellular organism can help in the prediction of its behavior and the correct decisions can be taken. The pursuit of stars is vital for the astronomer.
