Determinación del color en epicarpio de tomates (Lycopersicum esculentum Mill.) con sistema de visión computarizada durante la maduración

the evolution of color in tomatoes samples, during ripening under refrigeration or at room temperature, was studied by computer vision system (cvs). cvs consisted in a lighted stage, a ccd digital camera and a computer (laptop), all calibrated. the digital processing of images was performed with the adobe？ photoshop？ cs3 extended software, with which averaged images on l*, a* and b* coordinates were obtained. the proceeding tested, using cvs, allowed to study the variations of color during the ripening of tomatoes from images, by means of rectangular coordinates (l*, a*, b*). the ratio a*/b* and polar coordinates (c*, ho), showing statistically significant differences between samples determined (p<0,05).
