Color-speckle assessment in multi-primary laser-projection systems based on a 3D J_za_zb_z color space

Abstract

We propose and demonstrate a color-speckle assessment method based on a three-dimensional Jzazbz color space, which is appropriate for both three-primary and multi-primary systems. In the proposed scheme, new physical quantities are defined to describe the color-speckle characteristics, which provides a general and intuitive color-speckle evaluation for different laser projectors. Experimental verification is also performed using three-primary and six-primary laser projectors. The simulation and measurement results are consistent.

“…[ 44 ] A combination of constraints on the solution space from different priors/denoisers can take full advantage of the constraint characteristics, which can improve the quality of reconstructed images effectively, therefore the TV local constraint and multiple existing deep learning denoising networks are integrated in the TV‐CD algorithm. [ 45 ] It is worth noting that the TV‐CD reconstruction algorithm has the features of high interpretability, pre‐training free, and strong robustness, etc . The flowchart of the image reconstruction is shown in Figure 2b.…”
