Research on multimedia Video Synthesis based on color segmentation

Nowadays, the rapid development of film, television, animation and other multimedia industries requires more efficient video processing. Under the dual pressure of cost and time limitation, higher requirements are put forward for rapid video synthesis. Combining the commonly used RGB color space and HSV color space, a fast image segmentation method is proposed. Firstly, a Mask is calculated by using the threshold segmentation method. In order to reduce the influence of black on the final result, inrange used the second Mask to make the composition. The final result is multiplied by the original image, and the effect of black on threshold segmentation is effectively eliminated on the premise of not reducing efficiency and image quality, so as to achieve the most ideal effect. Compared with the previous real-time image segmentation processing, this method has been greatly improved in the degree of code simplicity, operation efficiency and cost. In the aspect of color extraction, as it is completed in the RGB color space domain, there is almost no color missing or redundant. The real-time segmentation and splicing of images can meet the basic needs of film and television shooting and greatly improve its efficiency.
