In order to produce Tristeza virus-free plants from Satsuma mandarin (Citrus unshiu) cultivars (Ishikawa, Sugiyama and Myogawa), unfertilized ovules of plants suspected of CTV (Citrus Tristeza virus), from Mazandaran Mahdasht orchard were cultured on 4 media. Embryogenesis of nucellus tissue of ovules from Ishikawa and Sugiyama cultivars on MS medium were 31% and 25% and on MT medium from Ishik...
This investigation studies the contrast across boundaries of shadows which are cast by moving vehicles or selected stationary objects in a traffic scene onto the road surface. If a sufficient fraction of this subset of hypothetical shadow contours is overlapped by strong edge elements, such a finding is usually taken as a cue that directed sunshine illuminates the traffic scene. Otherwise, diff...
In this paper, we introduce a novel colour substitution algorithm based on the dichromatic reflection model. We separate the object colour and scene illumination information in the target area of the original image. The object colour was subsequently substituted while keeping the illumination information unchanged. A new method was employed to estimate the object colour. We also developed a set...
