Rendering quality and performance greatly affect the user's immersion in VR experiences. 3D Gaussian Splatting-based methods can achieve photo-realistic rendering with speeds of over 100 fps static scenes, but speed drops below 10 monocular dynamic scenes. Foveated provides a possible solution to accelerate without compromising visual perceptual quality. However, 3DGS foveated are not compatible. In this paper, we propose Fov-GS, splatting method for scenes real time. We introduce forest...
We introduce the disocclusion headlight, a method for VR selection assistance based on alleviating occlusions at center of user's field view. The visualization VE is modified to reduce overlap between objects. This way, candidate objects have larger image footprints, which facilitates selection. modification confined frame, with continuity periphery frame rendered conventionally. provided automatically, without any interaction from user. Furthermore, our disoccludes destroying local spatial...
We propose a new scene-aware foveated rendering method, which incorporates the scene awareness and characteristics of human visual system into mapping-based framework. First, we generate conservative importance map that encodes features scene, acuity, gaze motion. Second, construct pixel size control using convolution kernel method. Third, utilize to guide rendering. At last, temporal coherent refinement strategy is used maintain smooth for adjacent frames. Compared state-of-the-art methods...
An integrated approach of ISODATA and SVR is presented to extract the objective information, e.g. wheat, which can adequately combine advantages both hard soft classification. It exploits classification method for typical feature mixed spectral unmixing feature. The accuracy assessment shows that this method, obtain a higher than either linear or practical.
