High quality and efficient light field image rendering based on white image compensation
Image rendering is an important technique in light filed image processing. It is to reconstruct the entire scene by combining micro images. However, due to the imperfect optical design of the light field camera, micro images suffer from the attenuation effect, which causes server blocking artifacts in the final rendered image. In this work, a high quality and efficient image rendering algorithm based on the linear blending and white image compensation is proposed. First, the compensation model is estimated from the white image. Then, an adaptive modified function is adopted to adjust the compensation rate. Finally, the light field image can be reconstructed by applying the linear blending technique. Simulations show that the proposed light field image rendering algorithm is able to reconstruct a high quality light field image with less artifacts than existing methods.
