Qualitative Comparisons Of Novel View Synthesis And Depth Estimation On Neural radiance fields (nerf) have shown promise in generating realistic novel views from sparse scene images. however, existing nerf approaches often encounter challenges due to the lack of. Given unposed multi view images as input, we predict depth and gaussian attributes from the images, as well as the relative camera poses between them. we unify a self supervised depth estimation framework with explicit 3d representation achieving accurate scene reconstruction.
Qualitative Comparisons Of Novel View Synthesis And Depth Estimation On In this work, we take advantage of both the regularization and depth based methods and propose a novel framework combining geometry and appearance regularization with the assistance of depth, aiming at higher quality view synthesis from sparse inputs. We introduce a multimodal depth re construction framework that leverages extremely sparse range sensing data, such as automotive radar or lidar, to produce dense depth maps that serve as ro bust geometric conditioning for diffusion based novel view synthesis. In this paper, we address single image based novel view synthesis (nvs) by firstly integrating view dependent effects (vde) into the process. our approach leverages camera motion priors to model vde, treating negative disparity as the representation of these effects in the scene. Single view depth estimation is a significant topic, and obtaining accurate depth maps with depth sensors is particularly challenging. we propose the atgannerf model, illustrated in figure 1, which utilizes prior information extracted from coarse depth maps.

Quantitative metrics applied to three real scene datasets, namely llff, ibrnet, and dtu, demonstrate that the method presented in this paper significantly improves the quality of novel view synthesis compared to current advanced methods, achieving enhancements ranging from 3.8% to 26.9%. While existing methods operating in this setup aim at predicting the target view depth map to guide the synthesis, without explicit supervision over such a task, we jointly optimize our framework for both novel view synthesis and depth estimation to unleash the synergy between the two at its best. We show that, on uncontrolled outdoor images, our approach yields geometry that is qualitatively superior to that of the depth estimation network alone and that the resulting models can be re illuminated without artefacts. We recast the problem of 3d point cloud estimation as that of performing two separate processes, a novel view synthesis and a depth shape estimation from the novel view images.
