Abstract
To improve acquisition efficiency and achieve super high-resolution reconstruction, a computational integral imaging reconstruction (CIIR) method based on the generative adversarial network (GAN) network is proposed. Firstly, a sparse camera array is used to generate an elemental image array of the 3D object. Then, the elemental image array is mapped to a low-resolution sparse view image. Finally, a lite GAN super-resolution network is presented to up-sample the low-resolution 3D images to high-resolution 3D images with realistic image quality. By removing batch normalization (BN) layers, reducing basic blocks, and adding intra-block operations, better image details and faster generation of super high-resolution images can be achieved. Experimental results demonstrate that the proposed method can effectively enhance the image quality, with the structural similarity (SSIM) reaching over 0.90, and can also reduce the training time by about 20%.
