We consider a model-based estimation procedure - namely a data assimilation algorithm - of the atrial depolarization state of a subject using data corresponding to electro-anatomical maps. Our objective is to evaluate the sensitivity of such a model-based reconstruction with respect to model choices. The followed data assimilation approach is capable of using electrical activation times to adapt a monodomain model simulation, thanks to an ingenious model-data fitting term inspired from image processing. The resulting simulation smoothes and completes the activation maps when they are spatially incomplete. Moreover, conductivity parameters can also be inferred. The model sensitivity assessment is performed based on synthetic data generated with a validated realistic atria model and then inverted using simpler modeling ingredients. In particular, the impact of the muscle fibers definition and corresponding anisotropic conductivity parameters is studied. Finally, an application of the method to real data is presented, showing promising results.

For humans, visual understanding is inherently generative: given a 3D shape, we can postulate how it would look in the world; given a 2D image, we can infer the 3D structure that likely gave rise to it. We can thus translate between the 2D visual and 3D structural modalities of a given object. In the context of computer vision, this corresponds to a learnable module that serves two purposes: (i) generate a realistic rendering of a 3D object (shape-to-image translation) and (ii) infer a realistic 3D shape from an image (image-to-shape translation). In this paper, we learn such a module while being conscious of the difficulties in obtaining large paired 2D-3D datasets. By leveraging generative domain translation methods, we are able to define a learning algorithm that requires only weak supervision, with unpaired data. The resulting model is not only able to perform 3D shape, pose, and texture inference from 2D images, but can also generate novel textured 3D shapes and renders, similar to a graphics pipeline. More specifically, our method (i) infers an explicit 3D mesh representation, (ii) utilizes example shapes to regularize inference, (iii) requires only an image mask (no keypoints or camera extrinsics), and (iv) has generative capabilities. While prior work explores subsets of these properties, their combination is novel. We demonstrate the utility of our learned representation, as well as its performance on image generation and unpaired 3D shape inference tasks.

IEEE International conference on image Processing

作者： João Carvalho Manuel Marques João P. Costeira Univ. Lisboa Lisbon Portugal

We propose a method to reconstruct and cluster incomplete high-dimensional data lying in a union of low-dimensional subspaces. Exploring the sparse representation model, we jointly estimate the missing data while imposing the intrinsic subspace structure. Although we have a non-convex problem, we propose an algorithm robust to initialization. Extensive experiments with synthetic and real data show that our approach leads to significant improvements in the reconstruction and segmentation, outperforming current state of the art for both low and high-rank data.

This work aims to study and implement a reconstruction method of X-ray tomography able to reconstruct the image from insufficent number of projections. We proposed a new algorithm using the sinogram interpolation. The sinogram restoration is based on the incomplete sinogram available and generates additional data. The reconstructed images were obtained from the interpolated projections, using the classical FBP method, the quality of the reconstructed image depend on the quality and quantity of the projections. Our study showed image restoration performance in case of missing data and shows improved quality of CT images with reduced artifacts in the reconstruction results.

29th British Machine Vision conference, BMVC 2018

作者： Henderson, Paul Ferrari, Vittorio School of Informatics University of Edinburgh Edinburgh United Kingdom Google Research Zurich Switzerland

We present a unified framework tackling two problems: class-specific 3D reconstruction from a single image, and generation of new 3D shape samples. These tasks have received considerable attention recently;however, existing approaches rely on 3D supervision, annotation of 2D images with keypoints or poses, and/or training with multiple views of each object instance. Our framework is very general: it can be trained in similar settings to these existing approaches, while also supporting weaker supervision scenarios. Importantly, it can be trained purely from 2D images, without ground-truth pose annotations, and with a single view per instance. We employ meshes as an output representation, instead of voxels used in most prior work. This allows us to exploit shading information during training, which previous 2D-supervised methods cannot. Thus, our method can learn to generate and reconstruct concave object classes. We evaluate our approach on synthetic data in various settings, showing that (i) it learns to disentangle shape from pose;(ii) using shading in the loss improves performance;(iii) our model is comparable or superior to state-of-the-art voxel-based approaches on quantitative metrics, while producing results that are visually more pleasing;(iv) it still performs well when given supervision weaker than in prior works. © 2018.

U.S. Landsat Analysis Ready data (ARD) recently included the Land Surface Temperature (LST) product, which contains widespread and irregularly-shaped missing pixels due to cloud contamination or incomplete satellite coverage. Many analyses rely on complete LST images therefore techniques that accurately fill data gaps are needed. Here, the development of a partial-convolution based model with the U-Net like architecture to reconstruct the missing pixels in the ARD LST images is discussed. The original partial convolution layer is modified to consider both the convolution kernel weights and the number of valid pixels in the calculation of the mask correction ratio. In addition, the new partial merge layer is developed to merge feature maps according to their masks. Pixel reconstruction using this model was conducted using Landsat 8 ARD LST images in Colorado between 2014 and 2018. Complete LST patches (64x64) for two identical scenes acquired at different dates (up to 48 days apart) were randomly paired with ARD cloud masks to generate the model inputs. The model was trained for 10 epochs and the validation results show that the average RMSE values for a restored LST image in the unmasked, masked, and whole region are 0.29K, 1.00K, and 0.62K, respectively. In general, the model is capable of capturing the high-level semantics from the inputs and bridging the difference in acquisition dates for gap filling. The transition between the masked and unmasked regions (including the edge area of the image) in restored images is smooth and reflects realistic features (e.g., LST gradients). For large masked areas, the reference provides semantics at both low and high levels.

IEEE International conference on image Processing

作者： Maryam Babaee Yue Zhu Okan Köpüklü Stefan Hörmann Gerhard Rigoll Tech. Univ. Munich Munich Germany

Gait is a biometric property that can be used for human identification in video surveillance. Basically, different gait features require motion of a person walking over one complete gait cycle. For example, in Gait Energy image (GEI), average of silhouette images over one complete gait cycle is computed. However, in reality, there might be a partial gait cycle data available due to occlusion. In this paper, we propose a Generative Adversarial Network (GAN) in order to address the problem of gait recognition from incomplete gait cycle. Precisely, the network is able to reconstruct complete GEIs from incomplete GEIs. The proposed architecture is composed of (i) a generator which is an auto-encoder network to construct complete GEIs out of incomplete GEIs and (ii) two discriminators, one of which discriminates whether a given image is a full GEI while the other discriminates whether two GEIs belong to the same subject. We evaluate our approach on the OULP large gait dataset confirming that the proposed architecture successfully reconstructs complete GEIs from even extreme incomplete gait cycles.

This paper presents an accelerated proximal gradient technique for depth image reconstruction from incomplete data samples. One of the most technical challenges in depth imaging is to estimate a depth image from sparse measurements obtained due to missing depth values or fast sensing. Recent advances in signal processing, i.e., compressive sensing (CS) allows the depth image to be reconstructed precisely from far reduced measurements provided that the image has sparse representations in proper bases. Inspired by the CS theory, this paper formulates the task of depth channel reconstruction as a sparsity-regularized least squares optimization problem. To solve this problem efficiently, an iterative algorithm based on the accelerated proximal gradient technique is developed, which not only speeds up the convergence rate, but also enhances the quality of depth image estimation. Several experiments are conducted and the results confirm the efficiency of the proposed approach.

Binary tomography focuses on the problem of reconstructing homogeneous objects from a small number of their projections. In many applications, incomplete projection data holds insufficient information for the correct reconstruction of the original object. In this paper, we provide an optimization based method to select the "most informative" projection set, using information of global uncertainty. Beside the projection data we assume no further knowledge of the image to be reconstructed. Still, we achieve approximately as accurate reconstruction results, as it is possible to gain with a former method that uses blueprint images to find the optimal set of projections. We give experimental results for validating our approach on artificial images of various structures.
