Summary:A computer implemented method of estimating depth for an image and relative camera poses between images in a video sequence, includes backwards warping the source image to generate a first reconstructed target image, and calculating an initial image reconstruction loss based on the target image and the first reconstructed target image. Forward warping the source depth map is performed to generate a second reconstructed target depth map, and an occlusion mask is generated based on the second reconstructed target depth map. The method further includes regularising the initial image reconstruction loss based on the generated occlusion mask. Thus, an occlusion aware method of image reconstruction is provided via a combination of forward and backward warping which identifies and masks occluded areas, and regularizes the image reconstruction loss.
