Method for designing a quantized image for digital micromirror device-based projectors using a weighted evaluation function

In this study, we propose a method for designing color quantized images for use with digital micromirror device (DMD-based projectors. It is necessary to quantize full-color images if we want to achieve a high frame rate in DMD-based systems. The quantized image should be similar to a full-color image to achieve good results. The proposed method for designing quantized images is based on an evaluation function and a particle swarm optimization algorithm. We can improve the image quality and luminance of the image displayed by tuning the weight values of the evaluation function. We evaluated the quality of the designed binary images using numerical examples.
