Abstract: An image processing system for generating a high dynamic range image from a first image and a second image is presented. The system comprises a first displacement estimator adapted to estimate a displacement of image content between a reference image derived from the first image and an image to be warped derived from the second image. The system comprises a first warping unit that compensates the estimated displacement by warping the image to be warped resulting in a first warped image. The system comprises a first error detector adapted to detect geometric warping errors within the first warped image and a first error compensator adapted to compensate the estimated geometric warping errors within the first warped image resulting in a first error corrected image. The system comprises a high dynamic range calculator adapted to calculate the high-dynamic range image based upon the first error corrected image and the reference image.

Abstract: An apparatus for generating a model for pose estimation of a system obtains training data for a multiple locations. The training data includes one or more images captured by an image capturing device and the respective poses of the captured images. At least one data sample is generated from the training data for each of the captured images, where a data sample for an image is an assignment of the image and at least one other image selected from the training data to respective poses. A neural network is trained with a data set made up of the data samples to estimate a respective pose of a localization image from: the localization image; at least one additional image from the training data; and a respective pose of each of additional image.

Abstract: 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.
