EFFECT OF ILLUMINATION IN CHROMA KEY EFFECT IN THE REALIZATION OF VIRTUAL TELEVISION STUDIO

Abstract

This paper analyzes the effect of front and back light on the Chroma key effect in a virtual TV studio. The model of the system in which the experiment was realized is given. Different intensity of front and back light was used. The analysis of the front light of 200 lux, 800 lux and 1400 lux was done, while the back light changes in the range from 200 to 1400 lux. The characteristics of the analyzed images were clearly determined by their luminance histogram and parameters Mean, Median, and Standard Deviation. Chroma key effect parameters: Color Tolerance, Edge Thin and Edge Feather were used for the analysis. The results that are considered are tabulated and graphically based on the influence of light on the quality of the realization of the Chroma key effect
